Update to alsa situation

[Janina Sajka]

PCM means your digital data is being convertred into analog--stands for
"pulse code modulation." You can't hear digital, only analog. Humans are
analog sensate.

The weird thing which I still don't understand is that my headphones were registered in Alsa as PCM, and there was an aditional headphone setting in the mixer which didn't seem to have any visible effect.  I lowered the volume on PCM, and somehow the volume on the headphones lowered.  Very weird behavior if I do say so myself.
