Toshiba Conexant CX20551 (Waikiki) HDA-Intel No Sound After Suspend

[Matthew Warner]

Binary package hint: pulseaudio

I have a Toshiba P105-S6084 laptop I bought in 2006. Since then, I have repeatedly tried getting the sound to work after suspend/resume (it works upon boot). It currently works with a reboot, or if you boot with acpi turned off. I have setting editing /etc/modprobe.d/alsa-base.conf and adding options snd-hda-intel model=:
toshiba
laptop
auto
acer
3stack
3stack-dig

None of those have worked. I have tried this on every version of Ubuntu released since August of 2006. I have attached a text file that should contain all relevant alsa information. I am willing to try anything, but from what I have read this problem may be caused by something Toshiba did and not fixable......any help is appreciated.

(It can't be a pulseaudio issue if you need to pass kernel parameters to resolve the symptom.)

Please reproduce this symptom after installing linux-alsa-driver-modules-$(uname -r) from ppa:ubuntu-audio-dev (https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules) and rebooting.

The same issue occurs after the installation said Driver Modules. Any further ideas?

I have Toshiba P100, with the same Conexant. Mute and unmute, sudo alsa force-reload, add "options snd-hda-intel model=toshiba" to alsa-base.conf and delete ~/.pulse do not work for me.

Installed maverick beta, problem still exists as of 9/21/2010.

I attach file from 'ubuntu-bug alsa-base'

I am currently running Kubuntu 10.10 and would like to resolve this issue. Do you have any ideas on how to troubleshoot it?

[Daniel T Chen (crimsun)]

First, this is likely a bios issue; have you tried updating your mainboard's firmware? Second, please make sure you're using the latest daily build of the sound drivers from the ppa.

[Matthew Warner (mkw152)]

I am using the latest BIOS that Toshiba has released. I'll see if I can figure out how to get the latest sound drivers....

[Konrad (konradmb)]

This bug still exists in the latest alsa drivers build (ppa:ubuntu-audio-dev/ppa).

Hello:
I have same problem with toshiba p-100.
I think that is a compiled bios problem.
Any solution for this?

thanks.
