Now it starts getting interesting: while I can easily swap the left
and the right channel in my driver, the only thing this accomplishes is
to change whether the left samples are fed to the left or to the right
channel (and vice versa for the right samples).
Volume settings are handled by the AC'97 mixer driver which is generic
for all AC'97 sound cards. I must admit that my knowledge of AC'97 is
not intimate enough to know how to fix this. Especially since this
affects a lot of sound drivers.
Any ideas on how to fix this are welcome.
