I am running RedHat 6.0 on a laptop with a Yamaha sound card. It took a
bit of effort to get the sound card to record from the microphone or
line in, but now that I can I get very poor sound quality. The recorded
.wav files have a lot of static. I can play sound files recorded in
other ways (for example, ripped from a CD) the sound is fine, so I know
that it is the recording stage that needs work.
I got the settings for io, mss_io, irq, dma, and so on from Windows
(which is also installed on the computer) and wrote them into
/etc/conf.modules. Before I changed those settings I couldn't record at
all, though I could play files just fine. In windows I can record, and
the quality is just fine.
I am using wavrec to record to a .wav file, and wavplay to play the
Any ideas what could be wrong? Since there were more io settings in
windows than I could set in Linux, I tried all of the possibilities.
Not all of them allowed me to record, but those that did were all of the
same poor quality.
