I see it both in Playback and Recording and I can control it in both also.<br>
But not when Show: is set to "Applications"<br>
(Same versions of OS and pavucontrol as you have)<br>
<br>
I see it here:<br>
root2:~/>pactl list sink-inputs<br>
Sink Input #94<br>
Driver: module-loopback.c<br>
Owner Module: 33<br>
Client: n/a<br>
Sink: 2<br>
Sample Specification: s16le 2ch 44099Hz<br>
Channel Map: front-left,front-right<br>
Format: pcm, format.sample_format = "\"s16le\"" format.rate = "44100" <br>
format.channels = "2" format.channel_map = "\"front-left,front-right\""<br>
Corked: no<br>
Mute: no<br>
Volume: front-left: 60893 / 93% / -1.91 dB, front-right: 60893 / 93% <br>
/ -1.91 dB<br>
balance 0.00<br>
Buffer Latency: 7324 usec<br>
Sink Latency: 13960 usec<br>
Resample method: speex-float-1<br>
Properties:<br>
media.role = "abstract"<br>
<a href="http://module-stream-restore.id" rel="noreferrer noreferrer" target="_blank">module-stream-restore.id</a> = "sink-input-by-media-role:abstract"<br>
<a href="http://media.name" rel="noreferrer noreferrer" target="_blank">media.name</a> = "Loopback from USB Headset H540 Analog Stereo"<br>
<br>
So you could control it as a "sink-input" with<br>
pactl set-sink-input-volume 94 40000 (normal (100%) is 0x10000 or 65536)<br>
pactl set-sink-input-volume 94 80%<br>
pactl set-sink-input-volume 94 0.7<br>
<br>
Search for set-sink-input-volume in the pactl man page.</blockquote></div></div></div>
