I have a similar issue. However there is a difference of ALSA behaviour between the super user ( the account created during installation) and a subsequent one.
As the first user, $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SI7012 [SiS SI7012], device 0: Intel ICH [SiS SI7012] Subdevices: 1/1 Subdevice #0: subdevice #0 As a subsequent user, $ aplay -l aplay: device_list:222: no soundcards found... Infact during the same X login as the second user, I sudo to the first user account and can play the sound. Looks like some ALSA configuration issue. There is no difference in "lspci -vv" between the two accounts. -- /dev/dsp busy, but no program using it https://launchpad.net/bugs/76876 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
