Ok, thanks for the feedback. Seems like the driver should label the
control "Front" or "Master Front" instead of "Master".

"PCM" is actually a software volume control, which could mean suboptimal
quality at low levels, but maybe it's not noticable.

I think what would be slightly better would be the below, but I don't
think we have a port that actually supports your use case right now.

[Element Master]
switch = mute
volume = merge
override-map.1 = all-no-lfe
override-map.2 = all-left,all-right

[Element LFE]
required = any
switch = mute
volume = merge
override-map.1 = lfe
override-map.2 = lfe,lfe

[Element PCM]
switch = mute
volume = merge
