Description of problem:
I have a AMD Duron 600Mhz+FIC AZ11e (KT133+Via686B) motherboard. The
onboard sound card works great for playing music. But when I try to record
something from the microphone/line jacks, I get noise totally uncorrelated
with input voice. I have made sure that the proper input is selected for
recording (using gmix), the gains are set properly etc.
Steps to Reproduce:
1. Boot a AZ11e motherboard based box using stock RH7.1 kernel (also 2.4.7)
2. Select the recording source, gain using gmix.
3. Try recording using sox/grecord/dd if=/dev/dsp etc.
Actual Results: It grabs very squeaky noise. That noise has no correlation
whatsoever with the input waveform. While actual recording is going on, I
can hear that the speakers are actually giving out amplified sound of what
I am trying to record. But nothing goes in the grabbed file.
Expected Results: When I try to play back the recorded file, I should hear
back the same sounds that I recorded.
I have tried different microphones no difference.
I haven't tried out the thing under any other OS. I only have linux.
The box has 64MB of RAM.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases,
and if you believe this bug is interesting to them, please report the problem in
