[Karl Goldstein]

My Thinkpad W700 won't play any sound at all with Ubuntu 10.10. Here is the ALSA info script output:

Hi Karl, could you try installing https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules and see if that fixes your problem? Thanks!

[Karl Goldstein (karl-goldstein)]

Hi David, that worked! Thank you.

In case it's useful at all, I ran the alsa info script again so you can see what changed.

Hmm, you still appear to be using a model quirk according to your alsa-info.sh output:

model : thinkpad,

Can you remove that quirk from the relevant /etc/modprobe.d/* file, reboot, and confirm that capturing and playing back audio work correctly?

[Karl Goldstein (karl-goldstein)]

I removed the 'quirk' and rebooted. Here is the new alsa-info:

Sound still works, thank you.

Thanks for reporting back!
