Dear Maintainer,

I tried to play an MP3 audio file with Firefox.  There was no sound, so I
downloaded the file and tried with mpg123 and vlc, still with no sound.  I
checked the systemsettings and saw that there were no longer any sound-output
devices.  I also found an mpg123 core file.  The related lines from syslog are
below.

The output suggests that the problem could be in jack rather than mpg123.    I
will send a tarball with the MP3 file, the syslog, the core file and the CLI
output.

Thanks for your hard work on Debian,
Alison Chaiken
