i see, so it is software problem, nothing hardware.   can u recount
how do u get to this stage of getting the software to work again?
(did u do anything, or just simply reboot your machine?)

many bug report is linked to resuming from suspend, and the sound
driver somehow cannot suspend and resume cleanly......but then this is
also resolved at some stage.

The "lsof" which I requested was meant to see which processes open up
which sound ports, and possibly meaning that the kernel has to
multiplex these different applications together with regard to
transmitting sound to the speaker.   And if there is no sound, one of
these processes could be the culprit of the failure - which is why u
need to compare the lsof before and after the sound failed.   Or how
about comparing your lsof with mine:

/root>lsof |grep snd
pulseaudi 3404   tteikhua  mem       CHR      116,5
6059 /dev/snd/pcmC0D0p
pulseaudi 3404   tteikhua  mem       REG        8,6   362800
10213 /usr/lib/libsndfile.so.1.0.17
pulseaudi 3404   tteikhua   22u      CHR      116,7
6028 /dev/snd/controlC0
pulseaudi 3404   tteikhua   29u      CHR      116,7
6028 /dev/snd/controlC0
pulseaudi 3404   tteikhua   34u      CHR      116,7
6028 /dev/snd/controlC0
pulseaudi 3404   tteikhua   35u      CHR      116,5
6059 /dev/snd/pcmC0D0p
gconf-hel 3405   tteikhua  mem       REG        8,6   362800
10213 /usr/lib/libsndfile.so.1.0.17
mixer_app 3606   tteikhua   21u      CHR      116,7
6028 /dev/snd/controlC0

(Ubuntu 9.04 with linus-tree kernel at 2.6.35-rc3).

THis link have lots of suggestion on solving the audio problem:

Anyway, since it is working now.....I hope you can move on something
else.   Thanks.
