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

I have a look at my /proc/asound, it looks like following, ----- Is it
strange? I see many "off" ---- but I cannot turn-ONs them, by either
alsamixer or aumix, because in alsamixer jack-bars, them can not be seen
!

I suspect it's not a Conexant codec.  The driver seems to fail detection of
the codec.

This kind of problems is often related with ACPI.  Try to tune the ACPI
boot setting.
