Judging from /var/log/messages, it looks like the PulseAudio daemon cannot run with run with real-time scheduling because I am not in the pulse-rt group and PolicyKit won't give the daemon the necessary privileges. I will try adding myself to the pulse-rt group and see if that fixes it. The specific message (repeated quite a bit) is:
Dec 24 15:43:51 wasp pulseaudio[15121]: main.c: We are not in group 'pulse-rt' and PolicyKit refuse to grant us priviliges. Dropping SUID again. Dec 24 15:43:51 wasp pulseaudio[15121]: main.c: For enabling real-time scheduling please acquire the appropriate PolicyKit priviliges, or become a member of 'pulse-rt', or increase the RLIMIT_NICE/RLIMIT_RTPRIO resource limits for this user. Dec 24 15:44:01 wasp pulseaudio[15132]: main.c: Called SUID root and real-time/high-priority scheduling was requested in the configuration. However, we lack the necessary priviliges: -- [hardy] Intel audio sounds awful https://bugs.launchpad.net/bugs/178504 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
