Bob - 2007-01-28

I was hopeing someone might advise how I could go about trouble shooting
a microphone that has stopped working.  I have tried 3 sound mixers.
I have other machines that are working. A USB headset works but not
the analogue input microphone.

The microphone worked with SUSE 10.1 and the initial install of 10.2
but quit working afterr. I suspect, a software update.  It won't
work using krecord or skype.  Maybe I should enter this into
the SUSE bug system but I thought I would ask first for help here.

It is a dual boot machine and if I boot (rarely) XP then it works fine.
