Derek I completely agree with Adam's comments, Try using OSS and secondly, I would see if using the plain old onboard sound works, as that is what I had to do (Had to remove SoundBlaster live as I couldn't get it working properly under Fedora Core 4).

As soon as I switched to the OSS driver all was well. Also, linux still seems to have some problems with the sound blaster live series drivers. I have it on my pc at home with the live card and I still have problems with it depending on the application. My two cents..

Turning gain to almost nothing helps alleviate it, but it's still there when I play back a recording my sound or meetings via AGVCR. Everyone elses sound is fine (i.e. from the townhall), so it's not AGVCR. It's a 3Ghz P4, 1GB RAM, running kernel 2.6.15.6 and a Soundblaster Live! card. It's running Debian Sarge with ALSA installed and the appropriate driver in the kernel (EMU10k). ALSA OSS API support is also enabled too. I thought I would try using a different soundcard, a Soundblaster Audigy to see if that made any difference, but then I was unable to start RAT - it failed with a 'elem->type == SND_MIXER_ELEM_SIMPLE' failed'' message. I wondered if my RAT was old and didn't support ALSA or something, so I compiled the CVS version. Now I get the following when I start RAT (it doesn't die, just keeps printing the message with no UI) audio_read: Resource temporarily unavailable Googling for this it appears that someone posted about this problem a long time ago (2001) and never did a final resolution, or if they did they never posted it. Anyone have any ideas what the problem could be? I'm thinking that an SB Audigy under Linux for AG is probably fairly common so it's probably something simply and silly. I'm curious if anyone else has run into this problem? Couple of output of some possibly pertinent /proc files added below.
