skip fix

I have the UK T-Mobile MDA compact 3. (The HTC 3300 i think)

Anyway the rom information seems different to you guys, i had dropouts with my HT820's which i have tried to fix with the many fixes around, while i managed to improve the audio quality, i can only make the dropouts more frequent.

But after copying the registry settings here and running the fix, it now appears to be both good quality and not skipping at all.

The task manager fix didnt work at all and actually made my device run at permanent 100% CPU. I don't know what A2DPfix does, but it rocks.

THanks for the information and fix.

rom version - 1.13.110.1 WWE

ROM date - 9/22/2006

radio version - 02.49.90

Protocol version - 4.1.13.25

ExtROM version - 1.12.110.101

Restating my origional message!

If you have a HTC, buy the Logitech Freepulse Bluetooth Wireless Headset, for a almsot not gay looking pair of bluetooth headphones, they are the not-gay-est. They have decent bass, decent high, ok mid, but most notabely.... thy work so nice... OOO MAN I AM SO HAPPY WITH THEM... thanks sleuth.. but definatlly... you have to hold down the power for 45 seconds, it is deceiving because it really looks like you are doing nothing for that time and 45 seconds is an awful long time to hold down the stupid power button! You just wouldn't think it would work.. and then bam.. blue red blue red.. so anyways... buy the junk.. they are awesome, and strong and I have a big assed head so if they fit me, they will fit everyone, on some message boards they say they are uncomfortable ... but... honestly... if your just a normal person and not a fag... you can wear them 24/7 no prob. They are light.. work with the htc.. and i didn't waste my money and also.. it is strange .. i was talking to the logitech guys.. and they couldn't even tell me how to put it in discovery mode.. so weird... anyways.. if ya want some nice wireless headphones for the htc... x01ht.. this is definatlly it.

It would be nice to see logitech sell this headset w/o the included ipod adaptor. That would bring down the price a bit.
[8525, TyTN, MDA Vario II, JasJam General] URPREY:
A couple of quick questions: I just got a pair of Logitech Freepulse headphones. They seem to work great with WMP, but with TCPMP they don't work well at all (I can't get it to hand off the audio signal). Is there something I'm missing there?

Also, will this only work for songs or should it work for videos as well? Thanks.
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
@URPREY: no worries. TCPMP doesn't understand when the stream is redirected to A2DP. To get everything to work, first make sure TCPMP isn't running, then pair up your headset. Now run TCPMP and everything will go to the headset. Will work for videos too. However, A2DP's high proc utilization will slow down the video decoder noticably. Fixing this will require either AKU3.x, Widcomm, or Core ATI ImageON support for the Hermes.
[8525, TyTN, MDA Vario II, JasJam General] URPREY:
Thanks Sleuth! I'm not sure if I'm running into a limitation on these headphones, but even trying through WMP, when it changes to the next track the audio gets redirected back to the phone until I power the headphones off and back on again.
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
That'll cause TCPMP issues for sure...

edit: The more I think about what you said, the stranger it sounds. What's odd is this: how does the headset know the track is changing? Are you pressing AVRCP track buttons on the headset to cause this? TCPMP just streams everything to the WAV out device so it shouldn't care.
[8525, TyTN, MDA Vario II, JasJam General] URPREY:
This headphone has no AVRCP buttons, so it's just when it changes to the next song in the playlist or I manually change tracks. I agree - some definite weirdness going on.

CPU load

OK so i worked out my skipping audio isn't fixed.

After many combinations I realised whats going on. (i think)

On reset and loaded with just the basics, my CPU is running at 55% under no load. When i say have my bitpool at 48 - 58 the CPU runs at 98 - 99% constant, and occasionally hits 100% (at which point the audio clips out for half a second) I think this is pretty conclusive, as setting my bitpool to 10 and getiing a disgusting sound, runs the cpu around 85 - 87% and no audio dropouts. Am i missing sonthing here? none of you guys seem to be having this issue, maybe the way the MDA compact 3 is setup is taking up way too much CPU load. I have tried ending some some stuff running, but only end up crashing the device as they are clearly critical programs i'm ending. Any ideas? Anyone? I'm thinking of trying to overclock the CPU slightly to squeeze some more % out of it. :mad:
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
You could be onto something. On the TyTN v1.35 Rom which has efficiency improvements, I get about 70% CPU utilization with bitpool set at 58. Users of older ROMs get mixed results from this patch perhaps for this reason.
[8525, TyTN, MDA Vario II, JasJam General] checkd01:
nope definately not. Tried . ImmierSoft XCPUScalar.

original clock of 195 mhz stepped up several times to 247 mhz, while this dropped the amount of CPU usage to around 90% (not that much for a big clock) It still randomly drops out for a second or so, so while the CPU % may play a part, it isn't the whole story. I'm not happy. :mad:

The roms don't appear to be ready for what we want them to do, apart from some of the TYTN ones, which i dont know and would think would not run on my device. somebody tell me i'm wrong?
[8525, TyTN, MDA Vario II, JasJam General] checkd01:
Is it true that one cant use the widcomm or other bluetooth stacks on windows mobile 5 operating system, the makers have effectively prevented the use of such 'third party' stacks? why would they do that? restrict a stack that is underdeveloped and under supported, against, it seems, a stack that uses less power and is more reliable? is this another classic Microsoft tactic? Can anyone confirm that only the MS stack will run on WM5 and above, or is there any way of using a 'third party' party stack? I don't want much for xmas, just bluetooth audio that doesnt glitch and dropout. It also seems that MS leave it to the OEM hanset makers and software to drive the crap BT stack they provide.
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
BTW: I never told you this before, but welcome to XDA-developers checkd01! There's nothing like us IMO, in part because of the frustrations you describe. As evidence of this and in answer to your question, take a look at this thread. :)

I encourage you to spend some time with all the various topics here. Come up to speed on the areas where we are active. We only ask in return that you ask questions only after careful consideration and research. Everything you need is here and free for your use. Enjoy! Finally, if you can (and you seem to me like you just might have potential in this area): contribute!

edit: More on stacks.

The M$ BT stack supposedly underwent a significant update in AKU3. I am still eagerly anticipating a Hermes AKU 3.x ROM update in 1Q07. WidComm has its quirks too. Check out the Widcomm development thread on aximsite to see what I mean. Look for this in the X50 forums. My above link should give you a clue to its author as it did for me.

All this being said, I'm actaully quite happy with the M$ BT stack on my TyTN running the 1.35 ROM. My only complaint is 70% CPU utilization slows down video and the BT/WiFi radios can't co-exist.
[8525, TyTN, MDA Vario II, JasJam General] Godlio:
Suxxx

I have the most up to date device, which is Eten X500 with AKU3.2

And still skipping and dropingouts drives me crazy

Before trying A2dpFix i wasn't able to hear any sound from my Prolife BT55 headphones, now i hear good quality music, but still 1 time in every 40-50 seconds i hear a skipping for at least 2 seconds... damn it... why MS can't ever do something right!

Somebody can advise me smth?

Taskmanager doesn't help me more then that!
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
"POP!" (that was the sound of a bubble bursting & hopes being dashed)

:(
[8525, TyTN, MDA Vario II, JasJam General] emmett:
Great work being done here! Unfortunately I still get a skip sound every 40-50 seconds with this patch. It is better than before though at like once every 10 seconds! I'm sure people are telling Microshaft/Cingular/HTC about this, right?
[8525, TyTN, MDA Vario II, JasJam General] checkd01:
Thanks for the welcome. :)

After much frustration, i am still in the same place. To maybe stop some people wasting their tim:) e, a couple things i found out.

1. The audio skips or drops out for a moment and continues after. I'm thinking somthing is interupting or overiding a priority.I tried it without the phone section working, thinking it may be that, nope iy isn't. WIFI is missing on the UK T-Moblie model i have, it's apparently been disabled by T-Mobile, so it's not that either.

2.) I gave noticed somtimes turning my head to one side cuts out the audio for a second, but other times it doesn't. It seems to be spardic and random.

3.) I found a firmware update on here for my HT820, but i can't put my headset in flashing mode, i think they are the later model.

4.) I am considering that there may be outside radio interference causing the random dropouts, it's very strange, on occasion i can start my album going and go all the way to work with zero dropouts, on other days, random glitches and dropouts. I would like to have an effe4ctive way of measuring the output of the bluetooth transmission to prove it is stable and not fluctuating, but i dont know how to do that. (it is certainly a suspect at this time)

5.) Of the registry settings, some didnt work for me, the priority 256 gives me no audio at all, the max bit pool at 80 makes it very unstable and bitpool of 58 also causes to much dropout. I am currently running BITPOOL 48 deleted maximum BITPOOL key. (please always backup your registery before making changes)

My investigations continue. If i find anything else out, i will post here for sure.

merry xmas folks
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
hey, if you have WiFi where you are, try turning the access point off to see if that helps.
[8525, TyTN, MDA Vario II, JasJam General] Moaske:
I found this little entry in his thread, and it's the exact same problem i'm having with my Trinity and Jabra 620s which is anoying me to madness...

Does anyone here know how this can be fixed ? On my iMate Jam when i used to turn on a headset, it immediatly auto-connected to the handset. But with trinity nothing connects unless i go into Bluetooth settings in the comm-manager... The only thing that does auto-connect is an incoming phonecall over my old mono SE HBH600 when i use it for regular handsfree...somehow the trinity picksup the old headset when call comes in.

But i want to be able just turn on the BT on trinity and having to do nothing more than simply turn on the Jabra to get the audio redirected in an instant: why does this not work ?

It's driving me nuts... :(

No issues here with skipping however... :)

Re: Yikes! I just fixed my A2DP

Hello Sleuth,

I install your patch and found the behaviour below

Player: pocket player

Setting: Decoder Priority "Below Normal"

Behaviour: Sound drop when i keep on click on my Dopod 838Pro:(

No sound drop if i never get touch during music playing:confused:

Setting: Decoder Priority "Above Normal"

Behaviour: No sound drop even i keep on click on my phone:)

BUT my phone response VERY SLOW.:mad:

I check the CPU and Memory consumption is just 2M Memory and

2-3% CPU consumption.

My Rom: 1.23.708.4

Rom Date: 07/24/06

Radio: 1.06.00.10

Protocol: 32.37.7010.01H

BlueTooth headSet: HBH-DS970

Is there any advise for me?

Thanks alot!!

How Do I Know if A2DP Fix is Running?

Like many of you I too am having skipping problems with my 8525 and BT-620's. Started reading this thread and installed the Task Manager program and still had skipping, then I installed the A2DPFIX1.0 CAB and did a soft reset. Still skipping.

Went into Task Manager to see if A2DPFix was running and do not see it listed in the processes? What name am I to look for? How would I manually start the program?

I did check the Windows/Start-up folder and A2DPStart is in there.

I am so looking forward to being able to stream Sirius over my headphones while working out!

Also, my processor is running at around 90% when WM and Sirius are running. Is this normal in your opinion to have the processor running with this high of a load?

Many, many thanks to everyone for their great posts.
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
A2DPfix is a service, not a process which is why you can't see it with the open source taskmanager referenced here. You'll need dotFred's taskmanager to work with services on your device. Also, my TyTN doesn't stream to bluetooth w/o skipping either. This patch corrected my skipping problem when listening to mp3s with coreplayer though.

The problem is that A2DP itself runs the processor at about 70%. With Sirius taking up that much more I would expect bad skipping.

This may be fixed in AKU3. There are mixed reports on this. We'll just have to wait & see I guess...
[8525, TyTN, MDA Vario II, JasJam General] GarrisRP:
Thank you for explaining this. Loaded some .mp3's and started listening. With the audio quality set at "highest" I am definitely getting skipping. Changed setting to medium (using Hermes Tweak Tool) and still getting skip but not as bad. Also, the CPU load is at 80-85%. Damn if I have just listened to Slow Ride by Foghat all the way through with no skipping! WTF...

What is AKU3?

Was hoping to leave the iPOD at home and stream some Sirius while working out but I guess that will have to wait.

I can't tell you enough who awesome the info is in this thread and you are to be commended for your help to all. Thanks for sharing!
[8525, TyTN, MDA Vario II, JasJam General] GarrisRP:
Hold On, I got something..... I lowered the BitPool rate to 24 and I am now listening to Sirius without skipping!!!!! CPU load averaging around 90%. Sound quality is a little "tinny" but is definitely acceptable for me.

I am super pleased with the result so far and hope it continues to be skip free!
[8525, TyTN, MDA Vario II, JasJam General] AndyDGS:
Erm, again for simple folk like me?

I've been skimming through this thread but admit it's pretty well all over my head! Is this dicussing the issue of Windows Media Player crashing if the GPRS connection is active, and does it provide a patch to solve it, for the O2 XDAIIi (Alpine?)?

I'm kind of hoping it does, as I'm keen to start enjoying tunes on the pda, rather than just waiting for the thing to crash!
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
@AndyDGS: this thread (generally) is about a patch fixes an A2DP skipping problem that's unique to the hermes. without it, on most A2DP headsets, songs sound like records with bad scratches. The success of this patch is dependent on a number of variables such as the ROM version and some registry settings.
[8525, TyTN, MDA Vario II, JasJam General] benmorris:
Thank you ..>Thank you. Thank you. Cingular 8525 works now with patch

Thank you for the patch. Resolved the skipping on my Cingular 8525 and Sony HBH-970.

However, with PocketPlayer, the buttons don't work on HBH. The play/pause/next track, previous track.

Any hints?
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
Pocketplayer doesn't support bluetooth AVRCP (AV remote control protocol). IIRC, the only players that do at this point in time are WM and MortPlayer.
[8525, TyTN, MDA Vario II, JasJam General] Stormdog:
Yes, it does..

If the WMP plugin is installed...

Works great for me...
[8525, TyTN, MDA Vario II, JasJam General] aswaddington:
Pocket Music 4.3.4 from PocketMind works and has AVRCP as well. I use it with Cingular 8525 and HBH-970 with success.
[8525, TyTN, MDA Vario II, JasJam General] daedalia:
benmorris; you have to install the Windows Media Player plugin adapter for Pocket Player to use your headset controls, works flawlessly for me. Check the Pocket Player website & forum for details.

[8525, TyTN, MDA Vario II, JasJam General] KingMinos:
Thx, it also worked for me... I have the jabra BT620s headset with e T-Mobile MDA Vario

Rom 1.21.114.3

Radio 1.05.02.00

It also doubled my range to a total of 7 metres without skipping...

Id had to adjust the A2DP registry entry UseJointStereo and put it to 0

It improved quality and made it skip less...

But now we have another issue, when you connect your headset it activates the Handsfree profile, instead of the A2dp wireless stereo profile...

The switching between phone/voicecommands/music back and forth goes well...

But is it possible to ever adjust this? So it will connect using A2DP instead of handsfree??
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
that's a quirk of the BT stack itself, unfortunately. the fixes are an improved ROM or a completed Widcomm stack. HTC is releasing a new TyTN ROM soon and superdave is close to having a widcomm update so there's hope for sure :)

Hi Sleuth

(another newbie) I have installed your CAB and the phone has the original (orange spv m3100) ROM1.23.61.4

I have paired it with the Jabra 620 the controls for play pause skip etc work fine but i can only get 2-3 sec of music before it cuts out.

would i need to change my ROM to fix this?
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
The original ROMs are problematic. Most report failure when attempting to use this patch on those.
[8525, TyTN, MDA Vario II, JasJam General] d1g3by:
Thanks!

I take it there is no simple CAB style ROM updates available? or is that just wishful thinking?

Where would i get the updated ROM and do you know of any threads that give a step by step instruction of how to update it?

I saw earlier in this thread there were some basics but a step by step would be great.

T-mobile MDA Vario II and Jabra BT 620s

Hi Sleuth,

I have a T-mobile MDA Vario II, rom version 1.21.114.3 date 20/6/2006. T-mobile Netherlands did not release any newer version than the original one.

I bought a Jabra BT620s stereo headset. Pairing was no problem, but the music quality was terrible and it skips a lot.

The first time I found out was that in the registry the UseJointStereo was set to 1 (!); I was listening to dual mono ... After changing the registry key to 0, the soundquality was perfect but there was still a bit skipping.

When I read all you advises I decided not to use your patch (because I have the first, original ROM) but edited the registry further like in the quote above.

Wauw! Everything worked fine. It was amazing that such a simple correction did so much!!!

Thank you very much for all. Now I can enjoy listening my music.

Many thanks from the Netherlands!!!

[8525, TyTN, MDA Vario II, JasJam General] ovidiugm:
Hi Sleuth,

You're the best! I installed the CAB and A2DP it's working fine, no skip for me.

I just modified

HKLM/Software/Microsoft/Bluetooth/A2DP/Settings

UseJointStereo = 0

to get stereo, but all other registry changes (and I tried a few - priorities, pools) proved to be worthless so in the end I reverted to the one above + your essential CAB.

A few mentions:

- out-of-the-box my M3100 had about one skip every 40 secs

- no, it doesn't work skip-free with WiFi on

- doesn't skip in videos but video framerate is unbearably low

- listening through A2DP will slow down the device (I wonder how other not-so-smart phones manage to do this?! Some hardware-accelerated A2DP would have been great on TyTN, I think)

Welcome to XDA Developers!

First doublecheck that the A2DP fix service is running using dotfred's taskmanager. Next doublecheck your a2dp registry settings against what's been posted here.

Finally, its hit & miss. I wish I could tell you why this patch corrects a lot, but not all, issues. I have no XP with your headset. Can you get your hands on a known good headset to troubleshoot?

Hi mate, thanks for this patch !

Just tried it on my prophet and it worked GREAT, no more sound drops. Thx !!!

One (big to me) downside, my cpu clock scaler app (battery status), keeps showing 100% cpu load, which results in a constant o/c.

I'll contact the author and ask if he may add your trick to his (great) app.

Didn't notice any trouble except that one, I'll keep testing once my o/c problem will be solved :)

it's still bad quality sound btw, but flawless now :)

One step forward !
[8525, TyTN, MDA Vario II, JasJam General] Sleuth255:
What headset are you using lastnikita?

quality can be changed with UseJointStereo and Bitpool registry settings. If you haven't played with these yet then try setting UseJointStereo to 0 (gives true stereo sound), then change BitPool to 58 and MaxBitPool to 80.
