Question

AMD

After a fresh installation of ubuntu 11.04, I installed the driver for ATI HD6970 via Additional drivers. After that, the SB X-Fi Xtreme Gamer Fatal1ty Pro Series stopped producing sound.

Please help me restore the sound.

Answer 1

Remove pulseaudio (sudo aptitude purge pulseaudio).
Reboot.
Open the mixer (gnome-alsamixer or just alsamixer in the console) and make sure the volume levels are set properly and the main channels are not muted.
Check if the sound is working. If so, install pulseaudio back (sudo aptitude install pulseaudio) and reboot.

Answer 2

If you do not need sound via hdmi, you can simply fade snd_hda_codec_hdmi
