anybody having problems with the playback speed of .mp3 and .wav files? for some reason, on my sister's MDA, the playback speed of the audio files speeds up (like chipmunk speed).
I did a soft reset and that fixed the problem temporarily. But today, her phone rang and the ring tone was playing at chipmunk speed. I tried playing the audio files in Windows Media Player and GSPlayer and the speed was still fast in both programs.
any ideas or suggestions?
I had a similar problem after upgarding my 8125 to 2.17, I searched for audio problems on this forum and I came up with this... http://forum.xda-developers.com/viewtopic.php?t=46000&highlight=sound+fix
mine works fine now, and I haven't run into the same problem again, at least not yet.

I recently upgraded from the XDA II to the XDA Exec.
I'm experiencing a recurring (about every 5 seconds) glitch when using WMP to play back audio files (standard .wav files), stored on an SD card, through the Exec speakers. Playback through the earphones is fine.
I've tried another Exec and the speakers problem is still there, making playback of SD audio files through the Exec speakers unusable. This was never a problem with the XDA II.
I'm just wondering is this a problem with *all* Execs or is there something I've overlooked. If anyone out there has experienced smooth playback of audio files (from an SD card) through the Exec speakers I'd be grateful to hear.
Thanks in advance.
i use WMA files without a problem from SD card. why use WAV? aren't they huge? maybe you're not listening to music then.
i use a wave file as a sms alert on my jasjar and sometimes it sounds like it is stuttering. But only like 25% of the time that a sms comes thru. The file is stored in the device it self and not on a sdcard. thought that it might be related to the amount of programs running in the background.
Audio playback on Exec
Thanks a lot for replies.

I've tried both WMA files and WAV files: same Exec speaker playback problem (recurring glitch) with both. Interesting to learn that you don't have this problem with WMA files on your device. Is the Imate device identical in every hardware respect to the Exec? As yet I haven't come across, or heard about, an Exec which plays audio smoothly (from an SD card) through the Exec speakers.
Re. WMA vs Wav vs MP3 I occasionally use WAV because, while admittedly the file size is very large, the WAV format, being uncompressed, preserves the CD quality of the original (i.e. stereo, 16-bit sample resolution, 44.1kHz sample rate).

It's playback from an SD card that concerns me as I'd like to be able to store favourite tracks (and possibly my whole audio collection) as WMA or WAV files on an SD card, especially as SD capacities increase to 4GB and 8GB ......
I'd be very grateful if someone with an *O2 XDA Exec* wouldn't mind trying the following and reporting on if it worked for you:
1) Put an audio file (mp3 or wma or wav) on to an SD card
2) Insert the SD card into your Exec and play the audio file back through the Exec speakers using Windows Media Player
Thanks in advance.
Just tried some mp3's from an SD card on my Exec.
They play fine - no glitches, but quality from the speakers leaves rather a lot to be desired. I normally use earphones.

Thanks a lot Reteb. Much appreciated.
Tried some mp3 & wav files on Exec, no problems at all. They all play fine over the speakers.
Many thanks Reteb and Yen for testing SD-based audio playback through the Exec speakers. I'm going to go back in and get another Exec and hope for the best! At least I now know that, whatever the problem was, it's not a hardware issue across all Execs.
For the record this is exactly what I did:
1. I put some audio files (wav and wma) on to two different SD cards (a Sandisk card and an SD card I bought from Expansys). There was nothing else on the SD cards.
2. I tried both SD cards in my XDA II. No problem with playback of the audio files (using WMP) through the XDA II's speaker.
3. I then tried both SD cards in *two* Execs. No problem with playback through the earphones but a recurring glitch when playing back the files through the Exec speakers.
Hey I did also and had no problem and infact before now from last 4 months I've been listening with XDA Exec (O²) speakers and never noticed any problem except it doesnt have enough BASS as I'd like to have rest is fine !
I have the Softbank X01HT and I am trying to get my bluetoot headset working.
I have the i-PHONO PLUS BT450Rx Bluetooth Stereo Headphones.
It skips a little, and I think it may be because of how much it lags the PPC.
As soon as music is playing in media player through the bluetooth the ppc suffers heavy lag if I try doing anything else the music will highly skip and you can tell everything is very slow.
If i stop the audio from playing by clicking pause the lag is gone. I don't remember my old Cingular 8125 lagging this bad when bluetooth was playing, and that had half this processor, so I'm guessing something is wrong?
Has anyone else had this problem?
I would appreciate help,
Thanks
yeah it lags abit when the A2DP is on.
Well I just installed the a2dp cab fix I found on these forums and It seemed to help alot and I think it even fixed my skipping problem!
Can't say for sure yet have only tested for about 15 minutes, but it was skipping every 15 seconds or so before now no skipping at all.
My media player dosent skip now which is good.
But still my skype skips if I try using the headset with skype.
I'm guessing because skype takes more resources than media player.
Have you had any luck using a bluetooth headset with skype marktang?
no lol i have never used skype yet. and for the skipping problem i never had that. the only problem i have is that when im using stereo bluetooth the phone will lag abit.
Well I'm pretty sure that A2DP cab fixed the skipping on media player.
But I really want to use the headset for skype too, but I think because a2dp takes up resources and skype takes a lot of resources it is laggy.
Do you know of any way to free up resources? What programs I can close or something, or is there a way yet to overclock the cpu on the X01HT?
First Post, Hi to all.
Hardware:
I have just purchased an SPV M3100 (HTC TyTn) and I think it's great I want to use it to play music from my MP3 collection which is shared over the LAN and output the music to my new bluetooth A2DP speakers (Accoustic Energy)
Software:
The PDA is running WM5. I have installed V-mobile Software Network Browser which adds a network folder to the system and allows me to map my Computers MP3 shared folder as a network drive on the phone (This works a treat).
I am using CorePlayer as my media player as this is the best one I've found, it plays all my music and also my divx/xvid movies.
Problem:
I can play music straight over the network using coreplayer fine from the phone (WIFI & BT both turned on), but when I connect the BT speakers I get stuttering. Occasionally it seems to work fine, but most of the time the music is really broken up.
I can play music straight off the phone and send to the BT speakers and it works great, but only if WIFI is turned off.
It seems that the phone is maybe struggling to run WIFI & A2DP simultaneously, which is a little bit annoying.
Plea For Help:
Is there ANYONE who has tried to do this on ANY PDA? If there is, was it successful or are you having similar stuttering probs?
PS. I have tried the A2DP bitpool reg hacks with no luck, and even tried the 802.11g wifi hack in case it was a wifi bandwidth problem.
If Anyone can offer any suggestions or advice I would be most greatful.
//not sure if I posted this in the correct thread, it might be better suited to accessories?
I've got the tmobile MDA, it plays back AAC+ files great using TCPMP when not using bluetooth, but I recently got my first bluetooth stereo headset and I guess bluetooth must eat alot of cpu b/c AAC+ playback becomes choppy. Has anyone here been able to get smooth AAC+ playback using bluetooth on the HTC Wizard, and if so what did you do to make it happen? I tried another app called gsplayer but that made it even more choppy, and also tried fiddling with the buffer settings in TCPMP but made no difference.
Since I'm a bluetooth newb, I've got a couple more questions while I'm at it. Right now when I want to connect my bluetooth set to the phone I have to:
1) press comms manager button
2) click bluetooth settings
3) go to "devices" tab
4) rightclick my bluetooth headset and click "set as wireless stereo"
Now that's really a pain in ass in my opinion just to connect a headset. Is there an easier way?
BTW, is there a way to make Windows Media Player mobile to playback AAC+ files with the "+" settings? It plays them but sounds like 22 khz, I was wondering if someone has done a hack or something so it recognizes the full "spectrum" of aac+ files.
Sounds more like RFI interference to me.
Is there a wifi network nearby or is the wifi on the phone turned on at the time? Bluetooth uses the same frequency.
Pretty sure It's not an interference problem because it can pipe mp3 music over bluetooth just fine. I know aac is much more cpu intensive to decode compared with mp3. Are you able to listen to aac+ over bluetooth on this 200mhz smartphone?
FYI, there is a wifi network but I have wifi turned off on my phone.
My reason for saying that is that you said it plays back AAC just fine when not on Bluetooth. The other explanation I see being that transmitting data over bluetooth is also CPU intensive and that the two together are too much. But that's just a theory.
No, I've never tried AAC. The few AAC files I've ever gotten I immediately converted to MP3.
But you're right, mp3's play fine over bluetooth. Unless I get too close to my wireless router downstairs, then I get choppiness and skips like you mentioned. However, I do have my wifi signal strength amped up to increase the range.
I managed to solve the problem by overclocking the cpu as described in this thread:
http://forum.xda-developers.com/showthread.php?t=271012
I'm running at 252 mhz now and AAC+ playback is smooth over bluetooth and the system is stable, and feels overall snappier now. But still if anyone knows a solution w/o overclocking I'd like to hear it.

switching to a player requiring less CPU for AAC+ decoding may be of help. If you followed my articles in the General forum, you already knew the answer: most importantly, Pocket Tunes. Kinoma Play may also turn out to be OK, but it consumes more CPU (but still less than TCPMP)
See http://forum.xda-developers.com/showthread.php?t=350786 for more info and, again, do follow my articles.
Not looking to spend the asking price for Pocket Tunes or Kinoma Play, but thanks anyway for the suggestion. In your first post you described mplayer's cpu usage as "17%(!) for HE-AAC" which seems low to me, but you also describe the player as useless. That post was dated from 2005 however, so I was wondering if things have improved in 3 years. And I think I read somewhere that the Windows Media Player mobile for WM6 has AAC+ support- is that true? I'm reasonably satisfied with TCPMP except that I can't use use the media control buttons on my bluetooth phones to control it, so I'm keeping an eye out for something better (preferably free, but I'd be willing to shell out $10 to $20 on a good app)
when I stream music over bluetooth the music seems to speed up, weird uh?
and things happen to be even worse when the phone updated a few days ago.... do you have any idea?
format audio file?
rom?
