I have a strange issue that I'm hoping somebody here can shed some light on. My Nexus 5 is running stock KitKat ROM with Franco Kernel & GravityBox Xposed module.
The Bluetooth has always worked fine and paired up well with my car without any noticeable audio issues. However, last week I got a pair of cheaper Arctic brand (yes the same Arctic that makes case fans. LoL) Bluetooth headphones to have something wire free for when I go running (they get great reviews on Amazon). They are specifically these here:
http://www.amazon.com/ARCTIC-Blueto...0&sr=1-1&keywords=arctic+bluetooth+headphones
When they came in they paired up with my Nexus just fine and I had no audio cutting out issues over Wifi or LTE. Also worked great on phonecalls. The range is excellent as I can have my phone laying on my Kitchen table and be around 25 - 30 ft away across the house with a wall in between and audio doesn't cut out.
So fast forward to when I attempted to use them on a run. I have a Spi Belt to carry the phone when I run (it's basically a thin flexible waist belt with a stretchy thin neoprene pocket on the back to hold your phone snugly against your back (no bouncing) while your run. The first day I ran, I had the Nexus in the Spi Belt and the bluetooth audio signal cut in and out like crazy. The phone is in a thin neoprene pocket with only the bottom of my Nike Dri fit shirt covering it........and it's less than 3 feet from the Bluetooth headphones on my head. Needless to say I was very fruststrated.
I did some searching online and ran across some info on a possible bluetooth issue with the latest Qualcomm radio module update as well as people reporting Bluetooth issues in KitKat. One of the suggestions was disable the 5GHZ band for Wifi. I did this and when I ran the next day, with the same setup the audio only cut out a few times (instead of like 100 times the first day).
So my question is. Does anybody here know if there is a known Bluetooth issue? Is there a fix or workaround? I'm thinking it's related to the Bluetooth on the Nexus because the improvement was immense when disabling the 5GHZ on Wifi.
This weekend I am going to try turning the Wifi off completely, as well as testing my same running gear setup with my sister's iPhone 5S to prove the issue is with the Android/Qualcomm Bluetooth. It's a VERY annoying issue.
If I hold the Nexus in my hand while running, the audio is flawless. However, I think it's interference related somehow since making the adjustment to the Wifi Frequency really helped the issue, even when the Nexus was in the Spi Belt strapped to my back and under my shirt.
Any additional information or suggestion is extremely appreciated.

Ok, so I am still working on narrowing down the exact issue but I have been able to narrow the issue down some more. I tested with my Nexus 5 in the running belt this weekend when visiting my parents over WIFI & LTE and was unable to get the audio to cut out once. So at this point I do not believe the issue is directly related to the Bluetooth connection.
When I went out after work today the issue returned. However, today since it turned cool here I was just walking instead of running and carried the phone in my pocket.....so I started to check the screen when the audio cut out. I noticed that the mobile data connection had dropped from "LTE" to "H" (which I believe is 3G).
Whenever I am out running I have the Runkeeper App running (which uses GPS), and then Tune-In Radio to listen to sports talk radio (streaming low bitrate audio over LTE).
Until I started using the new Bluetooth Headphones, I was running the same route with wired Sony earbuds and I did not have any audio issues. So at this point I am thinking that since LTE dropped off, there is something about the combination of LTE, GPS, & Bluetooth being active at the same time that is causing interference and causing LTE to drop and switch to 3G, hence causing the audio hiccup. (like maybe it bouncing between LTE & 3G).
Any thoughts or additional ideas to troubleshoot further? Even though I don't want to my next step is to try with Runkeeper/GPS disabled and see if the issue is still present (I really need Runkeeper to track my distance). Whenever TuneIn, Runkeeper, & GPS & Bluetooth are all enabled, the Nexus RAM is only about halfway full.
Thanks for any additional suggestions. This issue is driving me nuts.

Another update....
Ok, I'm out of ideas. It makes no difference what apps are running and although LTE does drop to 3G in some areas, that doesn't appear to be causing any issues.
After doing some more googling I ran across a thread on Reddit where a few users had stated that using a custom kernel that has the minimum CPU frequency set at 300 MHZ which is lower than stock could cause audio stutter in some audio players. So I tried bumping my min cpu freq all the way up to 672 but that seemed to have no affect on my audio issue.
As a last resort to eliminate the Franco Kernel as a possible issue, I flashed back to 4.4.2 Stock Kernel.
I have the same audio issues on stock kernel as on Franco. At this point I guess I'm going to RMA the headphones to Amazon for a replacement pair.
Today while I was out running, the Bluetooth connection totally dropped twice. So the issue has to be with the headphones or the Bluetooth on my Nexus 5, correct?
This is one of the strangest issues I've ever had to troubleshoot on any equipment.

Same issue here but with a Bluetooth headset I use whilst on the motorcycle. It's pretty random when it happens though.. Some days it will be absolutely fine. Others (most of the time, unfortunately) it freaks out. I'll post back here if I figure out what's going on.

Cross-body interference........
Well after some more scouring the net I ran across this info. Looks like a crappy issue to have.
Cross-body Interference
A little known fact about Bluetooth is that the radio signals do not go through your body very well. This is because Bluetooth's radio frequency is blocked by water, and the human body is made up of mostly water. If you keep your cell phone in your pocket and your headset in your opposite ear, then it is possible the connection may be weak, which can cause some interference issues. Many cell phone manufacturers are aware of this issue and have attempted to compensate by boosting the power of the Bluetooth radio.

I am going to give the Motorola Motorola S10-HD Bluetooth headphones a try and see if I have any better results with them. I just don't see how you can EVER have direct line of site with your phone in your pocket or strapped to your back in the Spi Belt.
Some equipment must have fewer issues than others because I would think this would be something a LOT of people complained about, but I had trouble running across this possible issue on the net.

Same Nexus 5 bluetooth issue
I also have a nexus 5 and I am experiencing the same issue with my Denon bluetooth headset.
At first I thought the noise was caused by the Runkeeper app together with my music app, because when I just use Google Play Music I experience less interruption of the Bluetooth signal.
Did you find a solution to your Nexus 5 Bluetooth issues?
I have experienced the same thing. Just bought SONY MRD-10RBT headphones which cost me some good dime. and I use bluetooth audio streaming from my Xperia Z3. I put phone in my front jeans pocket and I get hiccups every 1-2 minutes.
what the hell?? is the technology still so inferior??? can anything can be done about this?
I'm having bad sound quality when making call through Bluetooth in my car. It sounds like the audio is breaking up. Anybody else have this problem? My note 3 was working just fine through bluetooth

I also noticed the same thing yesterday driving home. I did not have this problem earlier in the week. I'm not sure what is going on. This along with a strange wifi problem has recently surfaced. If I leave my wifi range and then return, it does not want to reconnect. I have to toggle the airplane mode then wifi will reconnect. I am running stock 11s rooted with 2.7.1.0 TWRP, Xposed framework, Xpoxed GEL, Gravity Box, Tasker, Autovoice.

Are you still experiencing poor Bluetooth audio in your vehicle? Mine is still the same.

I am. I'm looking for suggestions for things to try and improve the stuttering/skipping/dropouts that I'm experiencing when using my OnePlus One in media playback mode through my Chevrolet MyLink car radio. I have some additional details to offer and things I have tried:
1) The playback application doesn't seem to make any difference, the problem is most pronounced (unlistenable) when playing back music files and is highly annoying when listening to speech (e.g. podcast) files. I suspect the difference is the music having a beat that gets interrupted while there are some normal pauses in speech so the stuttering blends in a bit more. In any event, it's not a problem with the playback application.
2) It seems unlikely to be a problem with the car radio (Chevrolet MyLink). Though I haven't done extensive testing I have done some using my old Motorola Atrix HD with a nightly CM11 on it from a few weeks back and that does not seem to have the issue, or at least it is not nearly as severe.
3) When I use a third party bluetooth audio receiver (some cheap no-name one from ebay) the quality seems to be fine but when I try to go directly to the car stereo I get tons of stuttering/skipping/drop outs.
A friend suggested that I try running an alternative kernel and see if that improves things. Any ideas on whether that may be the case or which one might be the best to try? Any other suggestions? It's quite annoying that I can't playback audio through the car radio...
Thanks!
Anyone have any ideas? I tried running the Franco kernel tonight and it seems to have the same issue. I did some logcat captures and I seem to be getting a lot of "W/bt-btif ( 2104): btif_media_aa_prep_2_send congestion buf count 24" messages when playing back audio through the car radio. See the attached full logcat captures with both the stock and Franco kernels and connected to both an alternative Bluetooth dongle and to the MyLink car radio.
Any suggestions?
After further testing I was able to determine this is an issue with the phone and not the car radio as I was able to find at least one other BT device which exhibits the same issue. I have created a ticket for this issue at: https://jira.cyanogenmod.org/browse/BACON-1005 if you are also experiencing this issue you are encouraged to go and vote for the ticket.
One question though. Do you have WiFi on when traveling in your car? Try turning it off and see if you still get skipping.
I do in fact have WiFi on at all times. I tried turning it off for the day today while doing some driving and it appeared to clear up the problem. I would think it's still a bug because having WiFi on should not prevent BT audio from working correctly but it at least gives someone a direction to investigate.
So I've done some slightly longer term testing and what I can say is the problem is not totally cleared up when WiFi is off but it is much, much better (definitely listenable). I will still get a couple dropouts when first starting a stream (sometimes, not always) but after 30 seconds to a minute it seems to settle down and be fine as long as I keep the WiFi off.

Just to clarify the situation..
My Xperia Z2 have the same issues.. It is not your phone but the Bluetooth stack in android that pretty much sucks the problems you are dicribing has been there since android 4.2 on a lot of devices.
I have just changed my Lumia 1020 out with this Z2 and call me disappointed in music quality! On the Lumia you would have trouble hearing a difference between jack/auxiliary and Bluetooth..
And today I did notice some dropouts even with WiFi off well into my drive but it was just a few packets I would guess more of an annoyance than a serious problem. I've heard about issues in the Android BT stack but the confusing part of that is why certain devices (such as my Atrix HD) don't seem to experience the problem.
I have a bluetooth stereo I use every morning in my home and a bluetooth stereo in my car. I almost exclusively use pandora, but I have also used power amp on longer trips. I have never experience this issue with my opo. I have ran 25-33 all rooted with no problems and am currently using CM11 nightlies. I also am not having any wifi issues.
Sorry it's not very helpful, but it doesn't sound like a widespread issue at least.
It certainly has something to do with the particular bluetooth implementation used by the receiver interacting with the OPO. As I indicated I have three different BT receivers I can test with and the problem affects two of them but not the other.
I don't know if this came from 6.0, because I can't remember this being a big problem until about two weeks ago.
When I'm listening to podcasts or audio books on bluetooth there are two kinds of disconnections happening.
The first is a normal one where the headset just goes "phone one disconnected" and suddenly I have sound coming out of my pocket. Annoying, but usually explainable by me bending over in the wrong way so that the signal suddenly became weaker or something. But this has been happening FAR more lately.
The other one is weirder. The sound will just drop out from the bluetooth device, and sound will come out of the phone. In this case signal strength isn't in any way related, because it literally happens when connected to a Logitech Boom sitting right next to the phone, or when I'm holding my phone in my hand and holding it right next to my ear where the headset is.
So my question is: is there a semi-known bug with Bluetooth in 6.0? If there is, how do I fix it, if there isn't... How do I fix it?
The only thing I haven't tried is reformatting the phone, but I'm considering doing that and derooting, since the only reason I'm rooted right now is to get rid of the wireless charging sound, and that's not that important to me.
I can't consistently reproduce it, but it has happened several times already. Every so often the phone will inject a nasty electronic squeal into the sound output, particularly noticeable on Bluetooth. I originally assumed it was just a lost Bluetooth packet or something, but then when I turned off the receiver the sound continued to come out of the speakers intermittently for about a minute! I have Jaybird Bluebud X headphones and my car connects via bluetooth as well.
I've also had issues with the phone audio getting super choppy on initial connection, and the Bluetooth module seems to have major interference with at least one of the 2.4Ghz Wifi bands... unfortunately the precise band that the router in the gym picked, so bluetooth audio + wifi is basically impossible (constant stuttering).
Anyone else having issues?
Nope not here ???

I've definitely had the squeal. I also had the low volume over Bluetooth while in call bug.
Yes! I'm glad I'm not the only one. I've had this happen several times (but not consistently) while playing music in Google Play Music.
I don't really have a recent phone to compare to, but the M8 never did that even as the rest of the hardware has been slowly dying these last few months. I guess it's more noticeable since on Bluetooth I'm usually in my car with the volume up... The sound is like fingernails on a chalkboard ?

I got that high pitch noise a couple of times on two different HTC U11 phones from the bottom speaker I think (not using a headset). It happened both times when I was using Chrome on a particular web page. I closed the page and it never happened again on my first phone. I exchanged that one due to a minor display defect and same thing happened on my second phone. On both phones it happened early on once I had everything setup and never happened again. On both phones the BoomSound notification appeared due to an ad on the webpage. Must be some weird software glitch. I do have my phone connected to my Gear S3 via Bluetooth. Not sure if that has anything to do with it. At first I was worried that there was a hardware issue. It definitely sounded like the squeal noise you described here. Almost sounded like an electrical interference.
Ive had this noise for sure, in my car on bluetooth with music player. Not sure how to duplicate, but definatley annoying.

Yes, I get it with my Jaybird X headphones at the gym too. I think you're right that it has something to do with the WiFi bands. I never have any problem in the car.

Sounds like most of you have gotten it when using a BT headset. Both times it happened to me I was merely browsing the web using Chrome and I was connected to my Gear S3 via Bluetooth. I wasn't even streaming anything, and I heard the squeal noise through the phone's speakers. Weird but luckily it seems to be a very rare occurrence.
I've a similar problem but with Wi-Fi in 5 ghz band while making a call. If I'm in a call and at same time the phone is sending or receiving data through a 5 ghz Wi-Fi I can hear a noise or squeal. If I make a call in Skype or WhatsApp using 5 ghz Wi-Fi the squeal is more notorious. It's like 5 ghz antenna is not correctly isolated from upper speaker. If I'm in 2,4 ghz Wi-Fi or not using Wi-Fi at all the sound is okay and no squeal. I can always reproduce this annoyance.
I have HTC phones since One X and never had one without some sort of signal isolation problem. HTC 10 was the worst at this matter as touching upper frames dropped 4g signal and interrupted bluetooth.
I just had this same problem. I remember someone mentioning this on the viper rom forums so I went back to find the post which was by @mhajii210 and linked this thread. I have no desire to trouble shoot the problem since by tomorrow this phone will be in the mail heading back to HTC but figured I'd post what I have to offer.
I did NOT have bluetooth turned on (not at all since last reboot) I was using wifi - most likely connected to 5g but not certain. I was browsing chrome when it squelled for about 20 seconds. After it stopped all was fine. Then about 15 man later when a notification went off it did it again. I opened gallary, played a video, and did it again. Even when I recieved a phone call it did it. Everytime boomsound icon was present. Turning screen off it still continued. After a reboot, has been fine. The only thing I wish I had done was force close chrome.
I hope this info if useful.

Thank you for your post. Sorry to hear you're sending the phone back. I strongly believe it is a Google Chrome bug. I've been using the Samsung Internet Browser Beta and so far it hasn't happened. It's still too early and I have to continue testing the phone since it didn't happen very often.

Is there any solution to bluetooth + wifi problem? I just got myself a sony wh1000xm2 and it is impossible to watch youtube video or listen music from spotify without interruption. But as soon as I either turn off the bluetooth or my headset, it becomes all good. I am using us unlocked phone and I am on Oreo
Hi - any fix in this? I get the squeal using mpow Bluetooth earbuds, but don't use Wi-Fi. I can live with that noise, but, unrelated to bt headphones, all of a sudden the bottom speaker on my U11 sounds like an air compressor going off whenever the boomsound icon pops up (while browsing) and notifications, alarms etc. I've rebooted and messed around with sounds but no go - anyone else have this issue??
Hi guys. I've had this happen seemingly at random on two different HTC U11 phones. At first I thought it's some weird Bluetooth and Wi-Fi interference, but it just happened again tonight with Bluetooth turned off. I've had my current phone for about a month and it has only happened twice, so it's a rare occurrence. What's happening is when I'm browsing the web with Do not disturb set to alarms only, on a 5GHz Wi-Fi connection, and I have two tabs open and one of the webpages is a javascript heavy site, it will start playing this weird electrical type noise through the speakers when there is an ad. The ad plays some video and is muted. The weird noise continues to sound off occasionally (maybe every 30 seconds or so), even after the ad has finished, until I close the tab. After that everything is back to normal. Maybe this is some weird Chrome bug? I have no idea, but I figured I would report it here. It seems to only happen when I'm using Do not disturb. At first I thought my phone has a hardware problem, but it has happened on two different HTC U11 phones, and it is very rare so it's impossible to troubleshoot. My wife is telling me to return the phone since the noise freaked her out. I only have 3 days to return the phone. Do you guys think there is something wrong with the phone, or do you think it's some weird software bug? Would you return or exchange the phone if it happened to you???
