The volume slider works when the default device is used, so I think
there are two possibilities:

1) It's something specific to the ALSA output, or

2) It does actually work even when the device is forced, but the sound
is clipping so much that there is no audible effect. On the other hand,
I think setting it to 0% didn't mute the sound...

I might do more tests later. It would be nice to get this working to
e.g. support setups with multiple sound cards (where the ALSA default
might not be what the user wants).

For now, however, there are probably more pressing matters to attend to :)

I see.

Thanks :)
