Thank you sh500 and talents

My O2mini work with S35... try a thousand times of hard reset and soft reset. The CAB is work! I no need to install the PHM but it seem OK to me. I think the major thing we need to do is modify the registry of BT patch. (the modify of bitrate)

Re: Jabra bt250v or bt500

I have a BT500, and also tried a BT250v. And no, they do not support A2DP. Wouldn't make sense, either, as A2DP devices should really be stereo. :)

modify bitrate

For the audio cut problem at O2 mini + S35 BT headset, is that the modify of bitrate in the registry could solve the problem?

use the software called "... registry editor"!

One friend of mine said, o2 mini was launched for more than a year, they have diference settings among them. Some of them need PHM, some of them need to change the registry... there is no absolute solution to solve the problem of dropping. Do some more trials to find the one you want.

I have installed this BCHS_FOR_POCKET_PC.cab and finally I got sound from my Motorola H-820 stereo BT headset, but the audio is choppy and only works with MS Media Player.

Is there any solution?

cut off problem

Hey folks, I've got the I-tech S35 headset installed with the bluetooth stack and on an XDAII and it works fine.

I've observed something very odd with regards to the cutoff problem that occurs every 30 seconds or so - the higher the bit rate of the mp3, the less the problem occurs. for example, if I were to play an mp3 with a bitrate of below 160kbps, the cutoff occurs every 30 seconds but when i use an mp3 with a bitrate of 384kbps, there's no noticeable cutoff. I think it has something to do with the fact that the bluetooth (at least on my unit) streams at 160kbps.

The thing I haven't figured out is how to get rid of the 5 second delay between mp3s. I wonder if there's a way to keep the bluetooth headset connected even when Media player is switching between mp3s to avoid the 5 second delay. :)
[JAM, MDA Compact, S100 General] fullgarage:

[JAM, MDA Compact, S100 General] DaleReeck:
Hmmm. I wonder why you would need a plugin for BT audio. A number of people have said certain apps didn't work, but others did. I've used the Widcomm bluetooth stack stereo support on many different PPC's and the BT audio is at a layer level. Any app that can produce audio and uses the standard calls to get audio from the PPC OS should work - you shouldn't need plugins or special versions. With Widcomm, I can't recall any app nolt working with it. It sounds like support for the MS bluetooth stack isn't quite there yet.
[JAM, MDA Compact, S100 General] fullgarage:
Hello.

The plugin is for the application.

withou the application does not handle bluetooth, with it it does.

That's all.

Rgd.
[JAM, MDA Compact, S100 General] DaleReeck:
But what I'm saying is, the application should not care or even knopw whether the audio is bluetooth or a wired headset. The application makes a call to the sound API layer of the OS. The sound API layer of the OS will determine how to output the audio, i.e., bluetooth or whatever. The app should never see or talk directly to the bluetooth stack - the OS layer does that as the "middle man" between apps and sound drivers. That's why with the Widcomm stack, any app will work and does not need a special driver or plugin, i.e., Audible.com's AuiblePlayer didn't have any special BT support, but it still works over the headset fine. That's why I'm saying MS has some work to do on its BT stack.
[JAM, MDA Compact, S100 General] jackleung:
I wonder why you wonder we "may" need a plugin for that. :lol: If U check this thread carefully, U will find this patch is not released by MS but CSR (a BT chipset company). It's "an extension to the native Microsoft Bluetooth stack and not as a replacement of the Microsoft CE Bluetooth stack". (from: http://www.csrsupport.com/document.php?did=1604&lang=zh-tw). Simple said, it's works on top of MS BT stack (it's probably an application layer stack).

We all know that Widcomm stack support A2DP natively and MS stack doesn't. You are lucky that U got PPCs that use Widcomm stack w/ native A2DP support. But as Magician users who stuck w/ MS stack, this patch is god send.
[JAM, MDA Compact, S100 General] Mvmajorem:

MortPlayer won't play any audio over BT on my Magician.

[JAM, MDA Compact, S100 General] hell_citizen:
The key word here is should.

afaik, the process should be something like this:

1. application asks sound api to play some file

2. sound api chooses appopriate codec and initiates it

3. the codec starts encode the file and writing wave stream to a buffer

4. sound api then tells to audio driver to play the wave stream

( !! there must be some error, i'm not so familiar with mmedia & system programming, so please correct me someone)

What i'm trying to say, logically, by replacing sound driver we can redirect that wave stream to anywhere, or by replacing codec we can redirect mp3 to anywhere (including default target). I think, there is second case (or another solution), not first, becouse whith unchecked Automute i can hear sound from speaker & headset simulateonosly while i can't hear taps, menu, and other system sounds in headset (they aren't mp3).

But all that are lyrics... i've tryed all solutins mentioned here (phm, priority modifier...) but can't solve problem with music cuts. Now i'll try updating radio to 1.13 and see, how it helps.

Btw, i have motorola HT-820. There is an mini-usb out on the headset. Does it means it can be reflashed too?? If nothing will help, i'll go torture their service center :twisted:
[JAM, MDA Compact, S100 General] morrow:
it's a little bit more complex. Normally a system with the sound hardware supports standard audiocodecs (44.1KHz, 16 bit etc). However a decoded mp3 to a "wave stream" in raw audio is to high to transfer via bluetooth to the headset. There is a lot going on here:

negotiation between headset and handset takes place to determine supported codecs of the headset. Most of the time this is a simple subbandcodec. so the original codec (mp3, wma, wave) stream is RECODED to the supported codec. this stream is send to the headset and then decoded to raw audio. If everything fails, a decision has to be made to send it to an alternative destination (such as the internal speaker).
[JAM, MDA Compact, S100 General] shinji21:
just wanna share my exp

Hi everyone,

Like so many people have experienced, I also have music cutoff problem with my Jam and the Motorola HT820. The music cutoff happens in about every 15 to 20 seconds.

Some people suggested installing the PHM hack master (even without modifying the CPU speed), and I of course did that too trying to get rid of the problem (I really want the Jam to be my iPod!!) While it improves a bit, I can still notice a tiny little skip every 15 seconds or so. It is not as bad as before, and I would say the cutoff problem is being reduced to a tiny skip problem.

I then actually ordered the Plantronics Pulsar 590 bt headphone. It gives no cutoff or skip whatsoever!! It works like a dream and now my Jam serves as my portable music player.

I dont know much about the technical details of A2DP or stuff like that, all I wanna share is the JAM aint work with ht820 and works like a charm with the pulsar 590.

I hope this helps people out there who are shopping for a bt headphone and dont wanna end up having the cutoff problem. I am sure there are other headphones that give you zero problem as well. Good luck!!!!

Ok, i see. The question is how it's implemented in case of this bt stack? Earlier in this topic HKLM\Drivers\BuiltIn\WaveDev is mentioned, where we can see values Dll=bpt_avdrv.dll and olddll=wavedev.dll, whitch (wavedev.dll) was Dll before installation. What is wavedev.dll exactly?

Am i right then saying what my mp3 is decoded to raw audio and then encoded to headset format? Then the probleblem might be in slow decoding and fast encoding? Or some other syncronization issue, perhaps between ppc and headset?

As we know, we can change the bitrate under \HMLM\SOFTWARE\CSR\MODULES\AV

1. I changed it to 212KBPS (the max output of bluetooth in o2 mini... that I think), the quality of the music is excellent but there are some dropping of sound while playing the MP3, the MP3 are converted by myself using the software of Cdex 1.51.

2. I changed the bitrate to 200KBPS, the dropping of sound is totally gone, and perfect streaming over the whole song but there is some distortion. most likely the highest bit of the music cannot reach!

3. WHY I mentioned "the MP3 are converted by myself" because when I play the MP3 converted by my friend using the Cdex ver. 1.4x are excellent (no lagging and good quality).

All the samples of MP3 is converted into a bitrate of 192KBPS in the software of Cdex (but difference version). Just for share and still work it out to find the ultimate answer.

Anyone is using another software to convert MP3 from the CD... any advise about the mentioned? THX!

I didn't think about it, but there migh be problem in codec? Today i'll try to use different codecs and bitrates. Most of my mp3 collection is downloaded from inet, so i can't tell you what software was used. But they all are 192 and the all crops.

Hell_citizen, thank's for your proposal but currently i'm not going back to my place before 5 days, so i can not send you a sample right now.

What is strange is that it sometimes happens with files coming from the same album, encoded in the same way.

I think maybe the bitrate is too low (no problems with 192 kbs or higher bitrates).

No way to spread it to bluetooth headphone with a 64 kpb song.

However when I turn the spv off during playback, the music plays for a while and then the spv locks up completely. Only a soft reset can wake it up.

yep I think too that the mp3 is decoded first to raw audio and then back to the headset format. It seems that the clicks from touching the screen are mixed with the audio (only in mediaplayer however).

You could be right about a software related problem. Streaming from my laptop using a belking bluetooth usb dongle seems very stable and I think is using a higher bitrate.

I wish i was getting choppy sound - then at least I could work on an improvement.

And i've been v. cautious. Upgraded my i-mate jam to 1.12; installed stack checked it worked with other devices. Jabra BT200 headset - OK. Ambeon GPS with Tom Tom 3 - OK. It's wasn't some cruel joke. :D

So I went ahead and ordered an i.tech (BlueBand) because so many others had reported sucess with i.tech - otherwise might have ordered a Bluetake BlueWalker MP02 (25% cheaper on Amazon - less risky).

Bought it; Got it; Paired it OK; Showing up in audio drop down. White headset icon showing. Great.
