oss4 just hisses

[mytharak]

All I hear is hissing noises when playing sound from any application including osstest. osstest passes ok but just outputs the static hissing noise. It's the same thing with VLC, audacious, etc. Can anyone tell me why this might be happening? I am running ubuntu 9.04 amd64 with the s3vibes driver.

I think I might have gotten it working... I'll know here in a little bit.

[mytharak]

Nope, It's still hissing at me.

[mytharak]

ok, so I finally got that fixed. I had to completely purge pulseaudio and lower the volume of vmix0-outvol in the mixer. It works but still has quality issues....

[mytharak]

Now that I got that working I don't have mixing, and the quality is iffy.

[cesium]

Are you sure vmix is enabled? vmix0-enable should be ON in the mixer, and the ossinfo output should show vmix is attached to the s3vibes (the output below shows that vmix is attached and enabled, but you may have changed the mixer since than?). If it is, you should have mixing... How did you test mixing? Note that osstest hogs the device unless '-V' switch is used, so you can't use it to test mixing...

[mytharak]

I got it all working. I just had to recompile. It looks like I missed a few errors the first time around.
