Title:
  Sound stopped suddenly with pulseaudio

Status in pulseaudio package in Ubuntu:
  Expired

Bug description:
  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
