I'm not sure if it's an alsa bug, since when I go above 100% with Fn-F6
alsamixer still shows 100 %
Moreover, while the sound is more or less fine via the speakers, the
distortion is really bad with my headphones - see the other thread I
posted about the multitude of outputs.
I'm attaching alsa-info.sh output, perhaps there is something
interesting in it.
