GNOME cannot find any sound device

Postby Honeyman » Sun Jun 15, 2014 13:17

For some reason GNOME doesn't detect any audio device anymore, meaning that all applications fail to give me sound (VLC, Totem, Rhythmbox). This happened without any upgrade.


There seems to be a kernel driver in use:

Code: Select all
# lspci -nnk
00:1b.0 Audio device [0403]: Intel Corporation Lynx Point-LP HD Audio Controller [8086:9c20] (rev 04)
        Subsystem: Acer Incorporated [ALI] Device [1025:079b]
        Kernel driver in use: snd_hda_intel
        Kernel modules: snd_hda_intel


Testing sound via KDE system settings is successful (HDA Intel PCH ALC282 Analog), but some audio devices (HDA ULI M5461 ALC882) are grayed out.

Any idea how I can get this fixed?

This totally escapes my logic. I had created a new user, to see whether this was a system-wide issue or only specific to my user. Well, others users had sound and I was member of the 'audio' group. So decided to move all configuration files and folders out of the way, log in again and voilà I had sound again. Incrementally I copied back the old files and folders, (graphically) logging in after each step to see if sounds was still working. I had sound until the end, that is until I had moved back the last single file. I do not get what had gone wrong. At least sound is working for now.
