For everyone having no sound after incomplete shutdown: --- sudo /etc/init.d/alsa-utils reset ---
NOTE: Until now the shutdown-problem ("Shutting down ALSA...") occurred only once for me. After using Power Off Button Ubuntu restarts without sound. But aplay shows following output: --- aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: AD198x Analog [AD198x Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 --- -- MASTER storing ALSA mixer element values during shutdown hangs nondeterministically due to internal alsa-plugins pulse check https://bugs.launchpad.net/bugs/274995 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
