Hello everyone,
I'm having trouble controlling the sound level of my sound card,
specifically volume adjustments using mixer and other volume control
tools don't change the actual volume.
For example when playing a MP3 at 1% volume the sound is unbearably loud
and moving the volume to 100% doesn't affect the volume, at 0% there is
no sound.
I have tried using mixer with no -f argument and also tried adjusting
the volume for each dsp entry in /dev with no effect.
