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: http://swiss.ubuntuforums.org/showthread.php?t=1468048&page=2 Anyway, since it is working now.....I hope you can move on something else. Thanks.
