Hi, When I first set up my Ubuntu machine, everything worked fine. But for the last few months (I don't remember exactly how long), my mic has refused to work. Nothing I use can pick up any signal from it. I've tried all the mixers (alsamixer, kmix, the built in GNOME mixer), and none of them show the mic as muted. Is there a way to reset ALSA's volumes and other mixer settings to defaults? I can't seem to find information about this online, and this lack of a fully working sound system has me on the end of my rope. Info: Ubuntu Breezy 5.10 Linux pippin 2.6.12-10-386 #1 Tue Jul 18 22:08:27 UTC 2006 i686 GNU/Linux I'm prepared to spend a good deal of time on this, but I don't know what I need to do. If you need more information, let me know how to get it and I'll be happy to share it. Eric

Hi, What kind of Mic is it? Some of mine have a small battery, and an on/off switch, which I tend to forget "on". Have you tried other mics?

Send output of "amixer". Also, what kind of sound chip/card? Onboard? Add-in PCI? -Jamie

Non-USB - the kind that just plugs into the sound card like headphones. It never had batteries or a switch. My roommate's mic doesn't work either - it's part of a headset, but doesn't require power either.

That's what I was looking for, but it looks Ok. What do the GUI mixers look like? gnome-volume-control, aumix, etc. Can you send a screen shot? It *could* be hardware. I had a line-in port fail on a PC recently. -Jamie
