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:

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
Subsystem: Toshiba America Info Systems AC97 Data Fax SoftModem with SmartCP

Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable-
Capabilities: [70] Express Unknown type IRQ 0


Here is the modprobe.conf:

cat /etc/modprobe.conf

alias scsi_hostadapter1 ata_piix
alias scsi_hostadapter2 qlogic_cs
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0


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
