I have an old noname sound card which I was able to get running with the
mad16 and mozart drivers. the output from the kernel is attached below.
If I play sounds from prerecorded mp3, realaudio or .au-Files, I get an
excellent sound quality.
The strange thing: If I try to record sound with a command (taken from
dd if=/dev/audio of=bla.au bs=4k count=4
then the sound is extremely noisy and sound as if it was played much too
slow. My voice sounds very deep and slow when I replay it with
cat bla.au > /dev/audio
I read that I need a mixer. I tried several ones, aumix, xmix and kmix.
If I start these, I hear a very clear signal on the loudspeakers. Still,
if I try to record and play the sound I get the poor quality.
I am trying to set this up to be able to telephone with speekfreely.
This programm also delivers the poor sound quality when reading in from
Can anyone point me into the right direction, please ?
The mashine is a Celeron 400MHz with 64M of RAM.
