Compatibility with pulseaudio-ctl

This is a similar program that exists for pulseaudio control. Since these tools live and die by the interface, I would request this interface to be implemented.

/usr/bin/pulseaudio-ctl mute        ==>  Toggle status of mute
/usr/bin/pulseaudio-ctl mute-input  ==>  Toggle status of mute for mic
/usr/bin/pulseaudio-ctl up          ==>  Increase vol by 5 %
/usr/bin/pulseaudio-ctl up 25       ==>  Increase vol by 25 %
/usr/bin/pulseaudio-ctl down        ==>  Decrease vol by 5 %
/usr/bin/pulseaudio-ctl down 50     ==>  Decrease vol by 50 %
/usr/bin/pulseaudio-ctl set 40      ==>  Set vol to 40%
/usr/bin/pulseaudio-ctl atmost 30   ==>  Set vol to 30% if current higher than that

From what I can tell, these are mostly aliases, there are only one crucial feature to implement:

• mute -> mute toggle
• mute-input: To Implement
• up/up X -> change +X
• down/down X -> change -X
• set X -> change X (not sure this is supported`
• atmost X: To Implement. Can be hacked around by reading the status, then writing the new value, it's lower priority.

There's also this issue to implement the opposite of this, pipewire support on pulseaudio-ctl:

Thanks for filing this. I didn't think about maintaining compatibility with pulseaudio-ctl.

Input volume control is something that should definitely be added. The default input sink is something that can be retrieved via pw-dump, so it should be the same sort of logic.

Atmost is interesting. Is that something people actually use?

I don't use it personally, but it might be very useful for automation. For example, limiting the audio level when connecting new devices, or when on calls?

FYI, looks like WirePlumber "solved" this issue by shipping a program that does basically the same thing:

Maybe I should redirect users to use wpctl instead?

[somini]

Yeah, I think WirePlumber and PipeWire are almost sister projects, it's the default session manager.

Not everyone uses wireplumber with pipewire, please don't abandon this project.
