Relationship between bluttooth audio, usb audio and alsa drivers

Hello:
 
I am having an interesting situation where I have upgraded the audio
drivers, library, and utils from 1.0.10 to the current dev release of
1.0.14rc2 and ended up breaking the bluetooth audio and usb audio
drivers.
 
The device that I have is an Intel HDA device with the STAC 9202 Codec.
When I attempted to run alsaconf, it would cause a kernel oops within
the blutooth audio driver. When I took that audio driver out (deleted it
and then re-ran depmod), then I found a kernel oops in the usb audio
driver (which accesses the microphone in a USB camera). When I deleted
that driver, I was able to run the alsaconf command.
 
How are the bluetooth and usb audio drivers integrated with alsa? If I
do a find within alsa, I do not find any source files for the bluetooth
driver. How does that driver know the data structures of the alsa that
is installed? What do I have to re-compile upon installing a new alsa
besides the alsa-driver, alsa-library, and alsa-utils components of the
newest alsa from the alsa download site?
 
Thank you
 
Truly,
 
Mark Allyn

There has been a lot of changes to the usb audio drivers since 14rc2
release.  You might try this daily snapshot:
ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver/alsa-driver-hg20070206.tar.bz2

I know the usb camera issue was discussed last week, and fixes are in
the repository.
