Buzzing/Humming Sound When Playing Video - Tablet MicroSD Slot Only - Asus Transformer TF700

Hi all, anyone having a strange intermittent humming/buzzing sound when playing video (in addition to the video sound) only from the microSD tablet slot? If I put the same video file onto tablet storage, or play through USB or through dock SD slot, there is no sound and it plays great.
It almost seems like the sound comes whenever the tablet is "thinking" - there are times when it is accompanied by a stutter in the video.
Tried this both with Dice and stock video player....same sound.

Just tried different MicroSD cards....all seem to have the issue.
Also just realized I only get the sound when I'm plugged into the headphone jack....Bluetooth headphones don't have the buzz

Yes I got that too. Every 20 seconds or so some weird sound comes up. Haven't tested it in a while to make sure if it still exists though.

Noticed the issue back in July. Between the time, I had replaced infinity, so not sure if it was due to different unit vs. different microSD (as I also changed my microSD card). But I no longer noticed the buzz/sound. The new microSD I was using was San Disk 32GB http://www.amazon.com/SanDisk-Micro...d=1353877861&sr=8-2&keywords=san+disk+microsd

Known Issues?

Hey all, I recently received my Gtab and wanted to highlight some issues and see if anyone else had experienced them or had solutions to them. I am running the latest vegan 5.1 or whatever.
1) I popped in my 8gb microSD card, but when I mount it via the notification bar, an 11gb storage device shows up. I am not sure if this is the internal storage or if it is my SD card combined with internal storage. If someone could clarify which one it is, and how to access the other storage device, that would be lovely.
2) When throwing a video onto it, I tried playing it with the stock video player, and there is no audio. I alternatively downloaded rock player and tried playing it through that, but again new audio. Do show and stuff have to be specifically converted for the g tab?
Thanks all
The audio sometimes turns off because it thinks headphones are plugged in. Plug some in an un-plug to get sound back. It doesn't happen to often but I keep a cut off Jack in my Gtab case to remedy the situation if it arises.
Are you sure your looking at sdcard 2? That's what your 8gb should show up under.

Stock Music App songs stuttering slightly

Hello all,
I got My VZW branded M8 on launch day and have been getting used to it and checking 20 times a day to see if a perm root solution has been found or better yet an S-Off method. On to my issue in the past few days I've had some time to listen to some mp3s from an SD card on the M8's stock music app and I have found that there is an audible stutter randomly occurring 3-5 times per song. The same mp3 played in poweramp plays smooth. The same SD card played the same songs smoothly in my DNA. So I'm lead to believe there some issue with the stock music app. I tested with screen timeout disabled, motion gestures disabled and still got the same thing.
Did anyone notice the same issue or is it just my phone.
It sounds like song skipped a beat or someone bumping a CD player, not really a sound but just the timing got out of sync for an instant. The first time I just thought it was a error in mp3 then I picked up that it was happening continually but could not be reproduced by replaying the same section of music. I love poweramp but the stock music player should function correctly on a flagship phone and IMO. I like the HTC stock music app as it lets me stream music from my DLNA server on my network, so I like it to function properly.
Kind Regards,
mc
Maybe try a factory reset since its obviously not a hardware issue if a third party app is working perfectly. Only music player i use is the stock HTC Music app and never had any issues with it across the board. Works perfect here even streaming over BT in the car or BT stereo headsets.
No stuttering here, but i've had tracks reset to start after short inactivity. I listen to audiobooks and had to go use Google Play Music because my chapters kept starting over after pausing them.

I've actually been having this issue but over Bluetooth only but my audio never skips when I have a 3.5mm jack plugged in. I'm getting a new Bluetooth device and I'll report back on my findings.
Have not had this issue with my Verizon M8. I have all my music (about 20gb) on the sd card, and normally play through the 3.5mm jack.
The one thing I did notice is, with my old htc phone, when playing music and a notification came in, it would interrupt the music and play the notification. I liked this because I would know to look at my phone. With this one, there is NO interruption of the music. So I can be in my car for a half hour playing music, and not know of any texts or emails unless I look at the phone. Anyone know a solution?
UPDATE: I tried using another Bluetooth device and the same problem occurred. Also to note, I'm having this issue with the stock music app & PlayerPro. However, if I reboot my phone the problem does not occur and I'm able to play music through my Bluetooth device without stutters.
@mc_365: Trying to see if we have anything in common. When music stutters, are you connected via Bluetooth? By any chance are you rooted & did you freeze any apps? Do you have the problem while connected to a 3.5mm jack?
UPDATE (9:32a PT): I just tried a factory reset & I'm still having the problem. Anybody have any other suggestions?

I'm not rooted and trying to play music through my Camaro bluetooth from Play Music it just constantly skips. I am running on ART and will switch back to dalvik to see if that fixes it. If not, I'm going to exchange my phone or return it all together.
UPDATE:
I switched back to Dalvik and did a factory reset to make sure everything was done properly. Now Google Play Music doesn't skip when I play music through my car. Are any of you on ART runtime by chance?
I just came back from Verizon & exchanged my M8; I'll have to check to see if that helped.

Are you playing music from your SD card or internal memory?

I never messed around with changing Dalvik/ART; I checked and I'm running Dalvik. Are you playing music off your SD card or internal memory over Bluetooth when you're having this problem?
I'm just playing mp3s from SD card on a regular pair of earphones. I think maybe my issue is the HTC decoder just doesn't like the CD rip I was playing, maybe the bitrate or the error handling within the app or something like that. I've played other mp3s now and can't say that this is something that is consistently happening.
I have all my songs on external sd card. I can try streaming Pandora in my car and see if any stuttering If that makes a difference? I did though download a few so to internal storage and played over Bluetooth in my car on the way home without stuttering. Played the same as the songs on my external sd card.
I have an obnoxious stutter on the Netflix app through speakers and headphone jack. Noticed it through play movies today also. Reset did nothing. Sadly it isn't noticeable for it to pass through the replacement check

I get the occasional skip when streaming over bluetooth from my SD card. I'd suspect it has more to do with the I/O read ahead or scheduler than anything. It seems to happen whether or not the screen is on, so I don't think it's a processor hang or anything like that.
I hope this update helps anyone with the same issue. :fingers-crossed:
*knock on wood
I noticed that the skips were less and far between if I was playing music over Bluetooth using the internal memory. So what I did is take another SD card and played music on that. This resulted in no skips that I could tell. Perhaps it might be a defective SD card or bad format so I reformatted the SD card completely (full not quick) and so far I'm having less skips in music. I ordered up the 128 GB SanDisk card & hopefully I won't have any skips using that card.
I'm thinking once we get a permanent root & S-Off we can try putting AOSP on our M8s & see if that eliminates the issue completely. :fingers-crossed:
If anybody else can share any suggestions on what to try, that would be great!

This is the problem I'm experiencing that brought me to this thread. Did you ever find a solution? Both Google Play Music and Stock HTC Music play over the notification. My podcast app, Pocket Casts, appropriately gives focus to notification sounds every time.

In sum, the potential fix is to change the read-ahead buffer from 512 to 1024, and the guy said it worked for several days with no further updates. He happened to be running Viper when he made the changes... apparently it uses the stock kernel. I am running CleanROM with stock kernel, so I just installed trickster and changed my read-ahead buffer to 1024. I'll report back if that makes a difference. There was one follow-up comment that it didn't make a difference in the stock ROM (edit - ahh... from broprah... any update to that?).
FWIW, I have been noticing this issue a lot BUT I only get it when streaming to my BT earbuds (with HTC Music, Google Play Music, and Pocket Casts). This stuttering does not happen when I use wired earbuds or playing over BT in my car. I understand the scenarios are different for everyone, but that's my own situation.

I ended up flashing Viper and I haven't experienced any stuttering since. In poking around, I see that changing the read ahead in the built in system tools only changes the internal read ahead. Further poking revealed that the external read ahead is preset to 4096kb, which could be the solution in the end.

I don't see a differentiation in Trickster. Do you know if that's just a Viper setting?
I was using FauxTool to check and change settings, regardless of kernel.
No such luck with my read ahead change. :/

Moto G 4G - playing music on USB OTG intermittently stops/starts/stutters

Hi.
A few weeks ago I bought a 128GB usb 3.0 stick with fairly decent read/write speeds. I put ~60GB of music and I regularly use it while driving to listen to music through the car stereo.
Unfortunately, every few minutes (sometimes twice a minute, sometimes not for 10 minutes or so) it'll have a moment where it pauses for about half a second and starts again. It seems as if it's buffering.
I use Poweramp on my phone and an auxiliary cable. I've also tried playing music through the phone speakers while it was read/writing another task to the USB stick, and I noticed the same effect, but more like every 2 seconds.
Any ideas how I can fix this? It's very annoying.
Is there maybe a way I could make it download the ~6-8MB MP3 from the USB stick to the phone's memory before the song starts playing, so there wasn't this latency/stop-start effect when playing content?
Buy a more well built otg cable or a micro SD card reader...
I have one from eBay (70 pence) and it does what you explain..
Although 1080p films and videos play a charm... The music loses quality while being sent.. Don't know why but a mehova micro SD card reader works good

Keyboard seen as jack plug

Sometime ago I copied few video files to my dock's sdcard, but than when i wanted to watch them, there was no sound (through speaker, jack headphones and bt headphones = totally no sound).
I tried other files from internal memory or tab's sdcard and there was no sound either.
However later i undocked the device and the sound returned. I forget about it for some time
Few days ago I got my MiKey fakes (I know that it's not original, but I got them for free) and it apps works that it asks You what was connected when You plug The Key (coz they have more than one similar things, but one app).
So when I connect the dock it ask to choose what is connected.
Coz of that I'm 100% sure doc is seen as something with "jack plug" and Android is using it as audio output.
Anyone knows what app or other thing can be cause of this problem?
Any app which has full control over dock, so I could try to clean it's data?
I'm on 4.4.4 PAC-man. Was thinking about clean flash, but there has to be a bug with latest version (have no other, links down) that since the beginning You got SystemUI FC (I was dirty flashing it over older version than, so everything was set up before and works fine till today)..

Galaxy S4 and S5 Audio Stuttering From MicroSD.

The card: SanDisk 128gb Class 10 MicroSD.
The phones tested on: Galaxy S4 and Galaxy S5.
Problem: For some reason, and I know it's not because of the card because it's brand new and works fine otherwise, but when I play music regardless through Bluetooth or headphones plugged in, I get microstuttering in music every now and then. I've also used did reinstalls of Android, formatted the card in both Windows and Android, and still happens. I noticed it seems to happen more when I unsleep and sleep the phone.
I heard something where people were saying to change the player in dev options between AwesomePlayer and NuPlayer or something like that; didn't work. Also, I've tried removing background apps, turning wifi on/off, data ETC, nothing seems to stop these microstutters.
While some may think it's the card because it's the same problem between two different devices, I doubt it's the cards problem, because I used the same card on a Pioneer XDP100R and it never skipped on that device. Is there something in Galaxy devices that would make audio skip when reading from MicroSD's? It doesn't skip from internal as far as I know, either.
I'll take any recommendations.
Bump.
