I have the same weird behaviour from the sound system. HP Mini 2133, fresh Karmic installation. uname reports 2.6.31-14-generic.
pulse says "card not found - dummy audio". After several trials I can say the problem most likely stands in the (configuration of) snd-hda-intel module. In fact, the original installation left me with no sound; after some googling I commented out in /etc/alsa-base.conf: options snd-hda-intel power_save=10 power_save_controller=N Still no sound. Then I added: options snd-hda-intel enable_msi=1 This partially worked. Now if I open Rhythmbox and start playing a long sequence of songs, no sound comes up, at the beginning. Then I do al "alsa force-reload" and the sound appears, even if still are WARNINGs complaining about fuse .gvfs-fuse-daemon file system.... BUT THE SOUND IS NOT PERMANENT: randomly it disappears, maybe after 5 seconds or after 20 minutes; every time it disappears I just do an "alsa force-reload", always with rhythmbox playing, and it reappears for another (random) period of time. Obviously the CPU load goes to 100% in sync when the sound is played, pulseaudio and pavucontrol accounting for a cumulative 50% of the load itself. Intersting to note, on another HP machine (Compaq 6710b) upgraded from 9.04 this issue is unknown... Hope it helps the ALSA guys. I'll keep in touch with this bug trail.
