Yes, it seems like the driver propagate this value to all the others
channels. Aftrer my first message I have continued to try to understand
the issue, and wasn't able to repeat "normal aqualung" case. Probably,
I have mistaken before.

So, the problem seems to be in the route table. I'll try to play with
it more before filing a new alsa bug.

I'm no expert at .asoundrc :-( but the '0.05' for the first two
channels in the ttable would correspond to -26dB. Do you have any
idea why those values are there ?
