I'm using 10.04 and some process is periodically causing a sound (more like a chime than a beep) and I can't figure out what it is. I don't want to turn off system beeps or sound in general, I just want to get this particular beeping to stop.
I have tried looking in /var/log/user.log and /var/log/syslog but dont see anything obvious other than perhaps:
Jan 13 15:45:16 awhitt-66131 pulseaudio[5606]: ratelimit.c: 130 events suppressed
However searches on this haven't turned up anything enlightening.
How can I track down which process is making these sounds?
