[ubuntu] Missing sound device on Zepto 6625WD

view full story

http://ubuntuforums.org – Just after I installed Karmic on my Zepto, the sound card showed up fine in the hardware tab of sound preferences. But after a reboot, it wasn't there any more. I can get sound working in boxee, via spdif some times. It seems really random if it works or not, when I reboot. I have tried following some guides from archived threads, but to no avail. Latest I tried this one, using alsa-driver-1.0.21, alsa-lib-1.0.21a and alsa-utils-1.0.21: http://ubuntuforums.org/attachment.p...7&d=1200150008 replacing "model=toshiba" with "model=zepto", as per the guide that worked for me on 8.10. Where should I go from here? Attached Images Screenshot-Sound Preferences.png (18.7 KB) (Hardware)
