I am going to try and change the "invalid" status for pulseaudio and alsa-tools.
alsa-tools, pulseaudio -- please re-evaluate. The primary issue seems to be that the alsa-tools are trying to find a pulseaudio daemon that is no longer running after the user has chosen to shutdown or reboot. It seems to me that amixer or aplay ought not try to access a pulseaudio process that doesn't exist. (The hang which is avoided by shutting down the network helps illuminate the issue, but it isn't the cause.) -- MASTER storing ALSA mixer element values during shutdown hangs nondeterministically if non-loopback network interfaces are still up 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
