[Bug 35717] Re: 'Master' needs to be exchanged with 'PCM' in order for volume hotkeys to work

[Ralf Nieuwenhuijsen]

According to this thread I found, the alsa developpers do not consider
it a bug:

Found at:  http://lkml.org/lkml/2006/8/10/84
I've cut and paste the relevant part here:

It's no bug.  The ac97 codec chip on your board has really no volume
control.

The PCM volume is an alternative volume control using DXS control in
the via823x control chip.

In other words, Master controls Line-In & CD, whereas PCM controls the
audio-output.  Which is the same behavior I've experienced. It's just
the way the hardware works.

So I suppose this bug should actually be assigned to another package!
Which package is responsible for assigning volume-up/down to the
multimedia keys?
