Extrem System Slowdown Using A2DP

[SchillDie]

Hi

I am Using Schaps WinMob6 with an Motorola S9 over A2DP, as soon as I start streaming the system slows down so bad that it is almost impossible to use!
Is this normal? Anyone using A2DP experiencing the same Problem? What can I do to fix this?

i have experienced the same thing no matter when ROM I use. theres not a lot of settings to change so they just sit in a drawer now collecting dust.

I'm experiencing this as well with Schaps ROM. If someone got it to work without problem, please let us know.

Hmm, I don't remember this problem when I was using Schaps ROM... what app are you using to stream. I pretty much solely used Coreplayer 1.1.1 for everything though.

Definitely not having this problem with K's rom which I'm testing now. It works sweet.

If I remember correctly I tried with both WMP and PP with the same result.

I believe A2DP takes a fair amount of CPU power - first the application needs to decode the mp3, then feeds it into the virtual sound device - bluetooth stereo - whose drivers then transcode the sound into something that can fit into Bluetooth's bandwidth. The transcoding has to be done in real-time so it probably has a high priority for CPU time. I don't think I've ever used a ROM where A2DP wouldn't slow down the device, and this includes an Axim x50v @ 624 MHz.

Hi Guys,
I have the feeling that things have gotten a bit better after installing Total Commander!?
Does this make sense?

Using TCPMP with You Tub plugin ( Vids Run great unless ;) A2DP :o/ )

It IS processor-intensive, particularly on Samsung CPU's, where it can easily eat 50% CPU time. This is why there's so bad a slowdown.

Read my related articles, they're all cross-posted to the Wiki here - I've elaborated a LOT on all these subjects.

mortplayer seems best for me, but yes there's always slowdown, the tcpmp thing; its the only program with which you can watch videos cleanly without skipping/slowdown via a2dp.

Darn :(
I just upgradet from a Magician in the hope that the Samsung would have more Power, but :o/ On my Magician ther ist almost no Slowdown using A2DP.

Are there any aps where I can OC my Samsung?

Sadly My tcpmp skips vids using A2DP :(. I guess I will only be using my S9 when Joging or Biking.

I'm having these probs on my 8525. No clue how to fix it. Theres a lot of storage and program memmory left on the darn phone. It used to work perfect, but suddenly had problems. The music stutters a lot with both wmp and tcpmp. I'm using the iphono minis with A2DP. These issues never existed with WM5 as far as I know, though the quality was of course lower. Perhaps the processes that up the quality of the A@DP stream are causing a trade of in CPU/memory consumption. Maybe that means lowering the quality (maybe via a registry tweak) somewhat will alleviate the problem?

I'd recommend switching to a wired headset :p

I got the same issue with my A2DP headset. It's not an issue that can be fixed with tweaking. A2DP is simply CPU intensive (not memory intensive).

Lowering the bitrate would help, but not enough I'm afraid.

Hey there,
I had a little trouble with helmi's wm6 (excellent rom) and the original wm5. The following link has some reg tweaks (http://forum.ppcgeeks.com/showthread.php?t=10668). It's still a little gappy, but much better. Also, the sound quality seems to be a lot better.
