In /etc/rc.local (before 'exit 0') I added:
alsa force-reload
BTW: my problems only started when I fixed the timidity startup by doing a 'chown timidity.timidity -R /etc/timidity/'. Otherwise timidity startup complained about it's homedir not being owned by itself. However, by removing that chown fix the sound problem persisted until I did the above :-| I guess the problem might also have been triggered by adding ubuntustudio-audio-plugins and canorus packages...
I did 3 things to get karmic beta to behave (so far reliably with both sound and timidity working) on my Dell Mini 10v netbooks.
This system has:
Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
Codec: Realtek ALC272
In /etc/modprobe. d/alsa- base.conf I added:
options snd-hda-intel model=auto
and commented out:
options snd-hda-intel power_save=10
