Summary:                    alsa 1.0.9rc4 + intel 82801FB/.../ = No sound (Benq
52-101)
Description: 
My notebook is Benq 52-101, update FC3 to kernel 2.6.11-1.14_FC3

alsamixer report: Card=intel ICH6, chip=Conexant id 3 (Question, Conexant
just support modem's AC-97 or else provide whole sound ? )

alsaconf: can find "Intel Corp 82801FB/.../ ICH6 family AC'97 Audio", and
will contine to "Have a lot fun".

I have ever, update linux kernel from 2.6.9 to 2.6.11(yum update, no
recompiling), and alsa driver from 0.9.0/1.0.8/1.0.9rc3/4.

Recomipling ALsa driver/lib/oss/tools/util.., with drive, ever try 
----- ./configure --with-cards=azx (error: no this card)
----- ./configure ; make; make install (no error report), not run
./snddevices

No sound ! So much days, so much test..... (if i915GM chipset + Conexant
chip...(see below lspci), will be powered by alsa-1.0.9rc4 ? --- if still
not, I will just wait for new alsa-driver.)

thanks

Well, the possible problems are:

- Some important codec-specific initialization is missing
- Conflict of audio and modem codec initialization, due to the combined
codec chip

The first one is hard to fix without a proper h/w information.

For the second point, make sure that you never load snd-intel8x0m (note
'm'), e.g. by removing the driver module file.  Then, comment out the
whole codes related with modem.

Can I help with it? You need a hardware information from me (customer) or
from BenQ?

Which 'codes' I should comment out? Comment out from what?
