You can easily test if the sound card works without changing its current
cat FILE > /dev/sound
where FILE is a non-zero-filled file (so that playing it as raw will produce
noise). Note that /dev/random seems too slow for that purpose (although it
was OK with 3.0 as far as I remember).
Now try changing parameters with audioctl and repeat the above test. What
changes trigger the bug ? Is it only mono/stereo ?
