popping<br>
and hissing when any noises are made in the room. The

appear to be intact and we believe we have traced the cause to our

Match Maker. Is this a required piece of equipment? We

be inducing noise.</blockquote><br>
Why do you suspect that? The fact that you get noises when there is
room noise implies to me there might be a feedback path from local
microphones to local speakers.<br>
<br>
Also check your gentner matrix to ensure that a local reinforcement path
isn't enabled. <br>

I think the two things may be related. It sounds like the kernel audio
drivers are now getting loaded instead of the OSS drivers. The
switch in audio drivers might have made the code that turns off the
feedback paths on the card not work.<br>
