Public bug reported: With 12.04, sound was working fine for a long time. However when I was listening to a youtube video, suddenly sound stopped.
So when I tried to start pulseaudio, I get the below error message. :~$ pulseaudio E: [pulseaudio] pid.c: Daemon already running. E: [pulseaudio] main.c: pa_pid_file_create() failed. So I tried below, and got the given output. :~$ pulseaudio -vvv I: [pulseaudio] main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted I: [pulseaudio] main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted .... etc (log attached). I looked at multiple help threads and tried solutions like below; with no luck. 1. removing ~/.pulse, ~/.pulse-cookie 2. check whether sound is in mute with alsamixer ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: pulseaudio 1:1.1-0ubuntu15.4 ProcVersionSignature: Ubuntu 3.2.0-60.91-generic-pae 3.2.55 Uname: Linux 3.2.0-60-generic-pae i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
