Re: Sound, Fedora 8, On Toshiba Satellite P107-S6147

$ lspci -vvv |grep -i audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller (rev 02)

I have lost sound on my laptop on the 2 latest kernel updates.

Sound still works on.
2.6.23.1-42.fc8

Any suggestions for how to fix this?

It would help to know what audio the laptop has. You may need to add
an option to /etc/modprobe.conf to specify the configuration used.

Here is the audio device from lspci -vb:

Here is the modprobe.conf:

Any suggestions are appreciated.

Thanks very much!


Can you run

cat /proc/asound/card0/codec#* | grep Codec

and post the results? This helps us sort out which of the plethora of
IHC7 cards you have.



Hi Rick,


cat /proc/asound/card0/codec#* | grep Codec
Codec: Conexant CX20549 (Venice)

I hope this helps?


Well, according to that, it's only seeing the modem part of your
sound card. It's not seeing the audio bit (and I should have caught
that from your lspci output).

So, something is very weird. I think F8 uses alsa 1.0.15 and it should
detect the chipset. The on-board sound is enabled in the BIOS, right?

Hi Rick,

The laptop model is actually a P105-S6147, not a P107-S6147 as my
subject line is erroneously stating. I had recently done a BIOS update
to BIOS version 4.00 for this machine. When I looked in the BIOS
options, I couldn't find one for enabling on-board sound. And I can't
remember whether I tested the audio under Windows Vista before, or
after, I did the BIOS update. I think it was before.

Also, I'm fairly certain there is only one keyboard shortcut for the
audio, Fn-and a little graphic for speakers, which seems to mute the
"Master" control or turn it back on. I'll double-check the
documentation. Pulseaudio is still complaining that it can't find the
"Capture" control.

Could I have made a mess of the audio with the BIOS update? Perhaps I
should backgrade the BIOS.

Bob
