Description Eric Toombs 2017-04-18 16:31:54 UTC

The current way to set volume looks like this:

% pacmd info |grep Default
Default sample spec: s16le 2ch 44100Hz
Default channel map: front-left,front-right
Default sink name: alsa_output.pci-0000_00_14.5.analog-stereo
Default source name: alsa_input.pci-0000_00_14.5.analog-stereo

*** copy default sink name ***

% pactl set-sink-volume alsa_output.pci-0000_00_14.5.analog-stereo 80%

It works, but surely there is room for improvement. Maybe something like

% pactl set-sink-volume default 80%

Or maybe even

% pactl set-sink-volume 80%

Another possibility:
% pactl set-volume "$(pactl get-default-sink)"

Comment 2 Eric Toombs 2017-04-18 16:44:44 UTC

I've since found @DEFAULT_SINK@. So looks like my first idea was already implemented. pactl get-default-sink would still be useful, though, for situations like

% pacat -d "$(pactl get-default-sink).monitor" ...

That particular example doesn't need any new features, because you can use @DEFAULT_MONITOR@.

More generally, though, I think it would be nice if pactl would have more fine-grained querying capabilities for situations where you need just one bit of information in a script (also, the current info/list commands are not guaranteed to not change their output format, so parsing pactl output in scripts is a bit fragile).
