[Q] Bluetooth + Wifi => choppy video - Eee Pad Transformer Q&A, Help & Troubleshooting

There is a huge thread about the same issue for the prime tablet, but I have it with my tf101.
If bluetooth speakers are used when streaming video over wifi, the video becomes very choppy and the sound is couple seconds behind. As soon as bluetooth is disabled everything goes back to normal in a second.
Is it a hardware issue?
Any ideas how to fix it?

I think it's an interference issue, but the odd thing is I just tried it with my old BT headset and had no problems. Maybe software? I'm rooted and running the stuff in my signature btw, perhaps the custom kernel and rom I flashed fixed something, or I never had the issue in the first place.

I'm having the same problem. I also have the problem that youtube won't output to my bluetooth speakers (Creative D200) and it causes nothing to output to the speakers after trying. This is true even after unpairing and turning bluetooth off and back on. This is not an issue on my Android phone (Galaxy S3), though the video streaming lags while outputting to bluetooth, just not as badly as on the TF101. I guess it has to do with the bluetooth audio codec used in the speakers (aptX).
Which bluetooth speakers are you using?

[Q] Nexus S bluetooth problems

Hey guys
Strange issue here. I paired my phone with my car through Bluetooth to make and receive calls using the car audio system. It works well.
However, if I fire Google Navigation, I can't here the spoken instructions through either the phone speaker or the car speakers.
I was not expecting navigation audio to be routed through Bluetooth audio, but I did expect the navigation instructions to come out of the phone speaker, as it does on the nexus one or the vibrant both running Android 2.2.
Is anybody else having this issue?
Thanks

did you flash a new kernel or anything because the kernel in the dev thread is known to break bluetooth
if it does this stock out of the box try doing a system restore and then take it back if its still acting up because bluetooth should turn on
yea i used the pkg one that had SU etc on it. Suppose Ill have to flash back to stock arg.
just so peeps know with the bt issue flashing this fixed

Bluetooth doesn't stream audio to car - what's your experience
I've got a Ford Edge with the new Ford MyTouch/Sync system.
The Nexus S connects to the Bluetooth just fine; makes and receives calls perfectly. It will also connect to the Bluetooth Audio Stream for music playback, but won't play the audio over the car's speakers. Also, sometimes it connects, holds the connection for just a few seconds and then disconnects. My SGS and Nexus One work as expected, as does the iPhone, so it doesn't appear to be an issue with the car.
Seems like a bug in the NS to me.
I'm curious if others are streaming audio/music to their auto's BT system without issues?
It would be especially nice to know what anyone else with a new Ford/Lincoln is experiencing, but I'd also like to compile a list of what cars work and what don't.
I'm going to have to find some other BT device that I can test the stream on to see if my phone works with it or not. Maybe my Nexus One dock? I've never used that to stream audio even with the Nexus One.
In terms of troubleshooting my problem, I've already rebooted the phone and the car, un-paired and re-paired the phone with the car.
I've got a Mazda RX8 R3 and the NS will pair with the in-built car BT but drops the connection after a few minutes. It then refuses to connect again unless I re-pair, then a few minutes later it drops and we're back to square one.
The car's in-built BT worked fine with my HTC Desire, Hero, iPhone 3G and Blackberry 9700 so I'm guessing the Nexus S has a Bluetooth issue.
Mine works fine on my aftermarket Sony receiver.
having issues with bluetooth audio too, stream keeps breaking every now and then. Any fixes?
I've only streamed to the car stereo and had no issues. The phone is only about 10cms away.
Haven't tried my BT headphones yet, maybe range is the issue.
*On original ROM.

tried placing the phone right next the the BT reciever and same problem. Only tried this once, maybe I'll try rebooting the phone.
no problem here
using Bionix 1.2
You're lucky, I can't even get BT music streaming to work with my car. No other BT devices to check with besides my Nexus One dock, which has no speakers.
BT works great for the phone, though, to make and receive calls.
Problem with Bluetooth
I cant get to work bluetooth on Nexus S.
When i enable it and try to send something from SGS to Nexus S it says me "This tranfer was canceled by the user" (Nexus S)
SGS says "Remote device rejected your request"
When i try send something from Nexus S, but use not function Send, i use function Bluetooth - it says me "The application Bluetooth Share (process com.android.bluetooth) has stopped unexpectedly. Please try again"
I tried factory reset, wipe cache, tried flash any other roms, but got NOTHING helpt me. I have this problem on 2 phones (2xNS).
Can someone give me files of BlueTooth share? (com.android.bluetooth)
That's an interesting problem you have. Mine did the same thing transfering from my computer to my NS. I just tried it again when I read your post (to make completely sure what the error was) and it has automagically fixed its self.
Well, seems i need a file \system\app\bluetooth.apk

DICE Player & sudden slo mo

When I watch programs on DICE Player (fully paid version) it will sometimes go into a slow motion mode and close down the sound. I use a small brick BT loudspeaker to get better sound than provided by the Transformer. Could BT be the culprit? Why slow down? Did not have the same problem on my ViewPad, hence thinking that it is hardware related to the Transformer.

It is probably the BT, IMHO. I had lots of trouble on my Archos 101 while watching videos with BT. Seems like high system loads will desync BT, and worse.
I'll try using a regular speaker, but kind of defeats purpose, I was thinking of using it on planes wearing BT headphones. No need to disconnect when running to the galleys.

HDMI audio stuttering (smooth video)

I'm connecting the tablet to my receiver (Denon AVR-1713) using the same cable that I checked with phone (Evo 4G, the only other device I have with HDMI output working) as perfectly working (A/V both play smoothly).
On the tablet, audio stutters (pretty severely) while video plays fine. I tried a few ROMs (KA, CM10.1, and Energy), and all ended up with the same issue. I also have a couple locked TF300Ts lying around, and both stock ICS and JB had the same audio stuttering.
Looking for differences between the phone and the tablet when playing audio, it appears that the PCM/Digital light flickers when playing via tablet (with audio coming through only when the light is on), and when the phone plays, the light stays constantly on.
I tried switching input source on the receiver to PCM (was on auto), still stutters. Switching to DTS results in no sound.
This happens for all audio (calls, notification sounds, music, youtube, etc.).
Any ideas on what's wrong? Using my brother's monitor with speakers, both audio and video play smoothly.
Bump. Anyone?
Bump.
Tried CleanROM yet? It may help.
Can you show us a video of it? That might help some people to understand your problem. I'm using cm10.1 and previously used energy rom and movie seems to be fine.

Nevermind, bought a microHDMI to HDMI cable on ebay, audio works fine now. The refresh rate of the HDMI output is off though (displaying dual overlaying images), but audio plays perfectly.
Weird, because the EVO doesn't have any of the problems this tablet has.
Well, figured out the problem for that as well, apparent this happens when the TV can't display that high of a resolution . Insufficient funds, and still stuck in the dark ages (of TV) :crying:.

Bluetooth audio choppy on wifi connection

Guys I have a Gionee A1 phone working flawlessly as my secondary phone.
Phone isn't rooted.
Since few months it is acting weird.
When I play Youtube or any online videos on phone connected to a Wifi and audio connected to a BT speaker or BT earphones, the voice is very choppy, skipping, stuttering and disturbing.
Earlier it used to work simply great.
The same earphones and BT speaker works flawlessly on my other phones.
But this doesn't happen when I do the above things on Mobile data connection.
I tried various tricks and solutions as below but none worked...
Factory reset
I upgraded the firmware and also downgraded but the issue still remains.
In Battery optimization do not optimize BT ad YT.
Clear data for both BT and YT and Wifi.
Battery saver mode is disabled.
Browser upgrade/ YT app upgrade etc.
Apart from this, there are no other issues with the phone at all. even calls etc work fine on BT earphones. The camera, battery wifi etc all wok flawlessly.
Is there any conflict arising between BT and Wifi connection within the phone?
I dont have any other wireless devices in my house at all.
Kindly help to resolve this minor looking big issue..
I think there is not much you can do.
From my experience with Bluetooth I can say it always failed for some reason. Like when bt mouse becomes unresponsive/skips when laptop is under load, or bt speakers (in home or in car) having choppy playback for no apparent reason.
The bt connection is so sensitive and it can be disturbed by other radio operated devices.
What you can try is using vlc player for music playback when connected to bt speakers.
I found this most useful, as it uses buffer in best way to prevent skipping/choppy playback.
Second idea is to unpair/pair your device and it should work fine, for some time at least...
Third thing you could experiment on is in Android settings, go to Developer options and change settings in the bt section (bt codec, bt sample rate, channel mode) to see if there are any improvements.

Question BT audio trouble?

Anyone else finding that the Bluetooth audio can be a bit hit and miss, the audio has just fully cut out on me, but it displays as if it's still connected and playing via the headphones. I had no audio through either headphones, switching BT off and on, and rebooting headsets didn't solve it. Rebooting the phone brought the audio back, phew!
Out of the two headsets I have, My cheap Sony WI-C310's seem to work better, Using my jabra halo smart headset, it doesn't seem to connect media audio if it's also allowed to handle calls. I have to toggle calls off and just media to use Spotify with the headset (this could just be that headset being weird, think it got discontinued for not being great)
Anyone else having BT audio issues?
I've got a Huawei smart band 6 connected at the same time if that's a factor, it wasn't a problem on my original Nord though.
I have been facing the same issue for a while now, it's pretty random. There are times where it works perfectly and other times it either doesn't connect at all, or has a very weird delay, where it's fine in the beginning of say a video and gets a delay mid way through it. There are times where it only connects to one earphone, just issues all around. Also am using the oneplus buds z2, so honestly would expect it to work flawlessly with a oneplus device. The earphones work fine with other devices.
I've been getting random drop outs.
Both with connectivity with my car infotainment system and my cycle computer.
When I had my OP7Pro, never experienced anything of the sort when connected to these two same devices.
I've also tried enabling Bluetooth Gabeldorsche in the developer settings, and that didn't make a difference.
Will try changing the Bluetooth AVRCP version to see if that improves anything (currently set to the default of 1.5).
Has anyone else played with those settings and tested the impact?
Tested with 3-4 Bluetooth devices and no drop outs.
I notice that when I put the device in aereo mode the Bluetooth remain active, but in the latest days this problem doesn't happen anymore, maybe was a bug of the first fw, and after last update they have fixed?
