[Q] USB audio stuttering - Sprint HTC One (M9)

I'm streaming digital music files to my new external DAC/Amp from my HTC M9. There is stuttering thru the USB out, but not from the analog headphone jack. Same results happen no matter which music player I use.
The amp has no issues itself, and works fine when decoding the same songs streamed from my pc.
Anyone have suggestions on how to attack this problem?

Is the Amp using the USB to decode MP3 "Files" (i.e. treating it as a "USB Drive")
Or is the M9 acting as a "USB Speaker" driver (didn't know it could even do that).
If the later I wonder if the Dolby stuff is getting in the way.
If it's reading the USB SD Card slow you might try reforming it in the phone. Could be as simple as a block size issue.

I have the same problem with m9 and DAC/amp OPPO HA-2...(
Did you solved it? (sorry for my English)

The problem disappeared after hard reset.

Glad the problem went away for you. How did you do a hard reset?

Sound stuttering via A2DP/Bluetooth

Hi, I am using the tornado a2dp fix and got A2DP working with a Sony bluetooth headphone set and the sound is great but it stutters. I tried WMA and even the HTC music player and its still the same (although a little better with WMA).
Is anyone else having these issues?
I may try updating the firmware (if avalible) or removing the A2DP thing and trying this instead:

has anyone tried this? does it work?
Does anyone having skipping music via A2DP? ANy fixes?
Thanks. all help appreciated!
I get the occasionall drop-out of music over a2dp. Every 30 seconds or so?
Not sure how to fix it - Works perfectly from my laptop. I don't think it's a signal strenght issue either as if I hold my jasjam next to my head it still does it.

Hi Just tried that prog and so far is NOT working......
Edit: It DOES work.
Bit fiddly to work it out but hey presto............. and stereo.
Listening to 'Pulse' ATM and not dropping out. Whahayyy!
i tried ripping a CD to WMA using media player at 128kbps and it works fine via A2DP with no skipping, so i think it just struggles with high bitrate songs and VBR MP3.
Update:
I tried an MP3 at 128kpbs and it skips, but when using a 128kbps WMA file it works perfect. So if you plan on using bluetooth headphones, get wmp 11 to convert everything to 128kbps WMA and you'll have not one problem.
Ok i have been playing with this and found a solution.
Use TCMCP. This plays AAC,WMA,MP3 and also video but if you embed the album art into the music file it will display this too. You can play the music at any bitrate and it doesn't skip with a2dp and bluetooth headphones.
And when you run this you have about 20MB avalible ram free.
To sort out your music and embed album art try music monkey.
Have fun!
I have the Pulsar 590A headset. Regarding stuttering audio; One thing to keep in mind; if you have paired it with your mobile phone, and later start a different pairing operation with bluetooth on your laptop, then the old connection with your phone may still connect automatically as a "mono headset" without you being aware of it. If you then connect the headset (manually) on your laptop to listen to stereo music (A2DP) the connection appears to succeed but you might get stuttering audio because you are also connected to your phone ! These seem to be two independent services that fight for bandwidth. I found that out when I happened to press the Dial button on the headset an to my surprise my phone (located in the hallway) called up my girlfriend ! And old pairing job I had done half a year ago and forgot about...Once I removed the phone pairing altogether (=phone link disconnected) the laptop music A2DP playback worked fine again. Can be a good thing to check in case you get stuttering audio.

any developers here? car audio request internal decoder for flac

i ve been searching everywhere and everything trying to get to play my flac collection in the car.
currently the car stereo manufacturers are beeing retarded and not developing any flac support( or at least not saying anything about it)
i checked rockbox, some off brand car stereos, even considered car PC)
but none of those options except car pc (EXPENSIVE) give me a digital signal option.
i know i can use it through AUX
and I KNOW ABOUT IPOD ALAC!!!! DAMN HOPE IT BURNS IN FLAMES !!!
everybody keeps suggesting it like its a piece of cake to convert a 200-300gb of CDs backed up in flac format.
so i come here to see if its possible to create an interface for the android phone so when plugged into a USB in car stereo it will act similar to ipod.
but so it would convert and send out a PCM WAV or other uncompressed format instead of flac or MP3

When you plug into a car's USB jack, all control is transfered to the car's system. The android just acts like a USB flash drive at that point. There's nothing you can do to the android to override this behavior. You'd have to hack the car's systems to do what you want. I've got the same problem. My car only supports mp3, wma and wav from the USB jack. It has an ipod jack too, but I've never owned one so I don't know what that may or may not do. I just use wav audio on a portable USB drive in my car to get lossless music. A year or two later model of my car has A2DP bluetooth, but I'll have to wait awhile before I can upgrade my car.
My friend tried his Iphone 4G in my car (pioneer DEH-P5100UB) by usb, he played spotify so not a file that actually was on his phone.
so if that works there must be some streaming from his phone to my receiver, so streaming from an android phone should work aswell...
sry for digging up an old thread but this might be the way to a nice solution to this problem.
androidphone with flac files --> flacplayer in phone --> send pcm(or whatever it is the iphone is doing) to the car stereo via usb
any thoughts?
Or Bluetooth?

my receiver don't have bluetooth.
i am still interested in the usb audio idea, if it is a digital connection that the car receiver plays or if the phone does the DAC job?
theres no direct interface for anything besides iphone.
i would be nice to plug in any flac capable phone and have control over it through your stereo but use the phone as a decoder and send WAV file to the stereo.
but i have no fn idea why car audio companies would not do it.
i mean its a damn usb interface, its already universal. and doesnt take much effort to get together and create a universal control interface so we can use something besides the damn iphone in the car. that sht is getting old.
thers one i phone
but theres hundreds of other phones and they all share 3 things in common:
android OS
USB
and fast processor that can handle decoding of flac files or any other media files.
yet theres not even a hint of support for these devices for some unknown reason.
Google music and power amp can play flac. I have flac in my phone too.
Accidentally sent from my Google Nexus S using XDA Premium
this is like beating a dead horse.
lol i dont care about AUX everyone has figured that out by now that you can hook up yor phone through aux
or use it as a media storage...

How to play music over the headphones?

Hi everybody,
Is it possible to play music over the headphones? I mean the original hands-free.
When I connect the hands-free to my TG-01 I can use it only to speak on the phone, but the music plays over the phone speaker .
It is bug, for me the worst

Try S2P, that works, as do a few other apps like PocketMusic and WinVibe
It is probably to do with the electrical impedance of your headphones, for instance, if you plug a 3.5mm plug that goes to your stereo, this is what happens, but if i plug in my headphones, works fine, so try another pair of headphones.
Well i was thinking he was tallking about WP7 My bad ....
I'm with WM 6.5 and play the music with Windows Media.
I found the problem. It works with the original headphones. I try with 5 different headphones and only two works. With the other 3 the sound automatically gone to the phone speaker.
Thanks to (InsertNameHere).

yep, this is a known problem with the TG01, it detects the impedence of the phones/cable being plugged in, if its of the wrong type, this is what happens, there are ways to trick it, you need to use a different headphone adapter though, there is a thread in the accessories thread.

Jawbone Jambox Bluetooth Speaker Problem - No Output

Hello All,
I have just purchased the Jawbone Jambox. Very nice bit of kit and the sound is great.
When I pair with my laptop, it works no problem outputting the sound from Spotify or Movies etc.
When I try and play music from my handset, it just comes out the handsets speakers even though it is paired. The same for games and video.
I have an HTC Desire with Cyanogen 7 installed.
The Jambox has a built in mic and works fine when paired as a hands free setup. I hear the phone ringing from the speakers so that proves it is working.
The Question????????????
I have done a bit of reading and have found some posts talking about on the iPhone, you can set what the phone outputs the sound to. ie. The Jambox rather than the builtin speaker.
I have not been able to find anything like that for the ROM I am using or even mention of it for other Android handsets.
Can anyone shed some light on this? Am I stuck with plugging it in or will another ROM solve the issue.
Thanks for your help in advance.....
Have you tried looking under the settings of the Jawbone Jambox? It should be located under the Bluetooth settings, then options of the Jambox. There should be two types of audio that can be directed. One is Phone audio, and the other is Media audio. Make sure the Media audio box is checked. I own one myself and have had no issues connecting. If all else fails, you might have to try another ROM.
Good luck.

Audio passthrough (DTS, Dolby Digital)

Hi,
I was wondering if anyone has managed to get Audio Passthrough working. So if you've got a movie file which has DTS or Dolby Digital sound, and you connect your phone with a HDMI dongle to your Audio receiver which can process DTS or Dolby Digital, to actually get surround sound out of it.
I've tried VLC and MX player, none worked. If I connect the exact same equipment to my laptop, it does work. So it must be either the video apps or the phone. I've tried multiple settings in the apps (of course I've enabled audio passthrough), didn't change anything.
Any help on this?
Thanks!

Alright but that's no surround sound. You're using a DAC which outputs stereo sound to a 3.5mm jack and a stereo headphones ...
I asking same question, do you find the solution now? I want to use smartphone to do audio passthrough to amplifier
