[Bluez-users] step by step - how to get your bluetooth stereo headset fully working with the bluez software stack under linux

[Jelle de Jong <jelledejong@powercraft.nl>]

Hello everybody,

I have been playing around with bluetooth devices under linux the last 
month or so. I got some very good and some very bad experience with it.

I am planning to create some wiki pages when I can get things working 
100%. However I still got some major issues that I need to overcome.

I bought a Motorola Bluetooth S805 stereo headset. It should get the 
following functionality:

- Playback of stereo quality audio without distortions and without delay 
when playing audio and video at the same time.
- Generic playback controls like playpause/stop/next/previous.
- Internal microphone to record audio, used for audio recordings and 
audio video conferences.

I was planning to get things up and running step by step:
- alsa configuration
- bluetooth configuration
- input device configuration

So the alsa configuration exist out of:
-- handle multiple audio streams (slave devices)
-- make the device default or as a plugin
-- use multiple bluetooth headset for the same audio (conference)
-- use multiple bluetooth headset per user based (multiseat)
-- force audio to use the correct bit-rate and frequency for the devices?
-- set-up correct buffer so that playback is without distortions of out 
of sync audio and video. (testing with totem-xine?)
-- configure multiple profiles for stereo recording/playback

Would somebody be willing to sent his working alsa configuration files 
that can do some of the above functions:

On this moment the headset plays stereo audio, but when watching video 
with and audio dvd on totem-xine the audio is out of sync and when 
scrolling or skipping chapters it get worse and hidd can even crash with 
segmentation faults. There is also a lot of noise distortions.

Kind regards,

Jelle
