Bug Description
Kubuntu installed from 6.06 i386 cd - kept updated using software update utility included with kubuntu.
When it does not work, the sound card still appears to be detected and configured. No sound output happens, however.
sudo alsamixer allows you to change volume - yet - no sound... not muted in alsamixer either.
I do not see any difference when the sound does work, either...
Sound appears to play in kde... but no sound comes out of speakers...
I do not know how to reproduce this bug other than reboot - I did see some others in the ubuntu forums having same problem, however.

Ok - I waited for the kde sound server to go idle (default 60 seconds) and then:
cat /dev/urandom > /dev/dsp
This appeared to work as normal, minus any sound output .... Could it be outputting to the headphone port?
ahhh - tested plugging in headphone set while running above command - that in and of itself did not fix it... However, I then opened kmix and played with master volume one more time ... sound came out speakers - not headphone. I will try this again next time i reboot and this does not work.
To recap the workaround I just found:
1) plug in headphone
2) mess with volume level
3) unplug headphone (or not - does not matter - sound is not coming out of headphone anyway)
