My system occasionally loses sound. In my case, it is invariably a

it and that will generally bring sound back without any more drastic
actions.
That could have been the problem.
Would you mind explaining a little more how you isolate the offending
process? Or post a reference URL that covers this issue?
Since, in my case, it is almost alway Firefox that has caused the
problem, I run the following script. All it does is parse the output of
'ps' and lists all Firefox processes that it finds. Usually there
should be three: one each for myself, my wife and my daughter. Anything
beyond that is suspect. If you should only have a single instance of
Firefox then shut it down and run this script. If it finds anything
then it probably needs to be killed. I also use this script to find
which of the three Firefox processes is hogging all of the memory, or
CPU time when the system grinds to a standstill.
#!/usr/bin/perl
&check_ps;
exit();
# Subroutines #
sub check_ps {
@message=`ps -eo pid,uid,%cpu,%mem,comm`;
$message_text='';
foreach (@message) {
($pid, $uid, $cpu, $mem, $comm) = split(' ', $_, 5);
chomp $comm;
if ($uid >= 1000) {
if ($comm eq 'firefox-bin') {
print $_;
}
}
}
}
