i think you are correct :) my sblive does the same....
btw. if talking about alsa...
what volume controls do you use?
i always tried to switch from oss to alsa,
but i always failed to find the correct volume controls ( there are LOTS
of them in alsamix ).
for example in oss it's simple:
front-volume = VOL * PCM
rear-volume = OGAIN * PCM
so if i want to adjust the volume globally i use the PCM volume control,
if separately i use VOL or OGAIN.
which volume controls do you use in alsa?
