Wrong volume displayed in Volume widget

The issue:

Qtile version: 0.22.1

A wrong volume (volume of Mic) is displayed for my device when using the Volume widget. The correct value should be the volume of Playback. The reason is that when running amixer sget command, the output is shown as below:

Simple mixer control 'Headset',0
  Capabilities: pvolume cvolume cvolume-joined pswitch pswitch-joined cswitch cswitch-joined
  Playback channels: Front Left - Front Right
  Capture channels: Mono
  Limits: Playback 0 - 50 Capture 0 - 30
  Mono: Capture 24 [80%] [-6.00dB] [on]
  Front Left: Playback 16 [32%] [-34.00dB] [on]
  Front Right: Playback 16 [32%] [-34.00dB] [on]

As we can see, the Capture volume is printed first. But according to the code here, it only tries to find the first percentage value. So this widget shows the Mic volume instead of the playback volume.

I think the solution is to filter out the line with Capture from the output or only keep the lines with Playback before processing it. I can open a PR if you think it’s a good approach.

We can leave it for now and wait until others come reporting the issue in which case we may as well generalise. Unless you’d prefer we fix the issue so you don’t have to use a custom command - that’s up to you.

ooh yeah good idea. We could try this. If you’re happy with your solution then that’s great, but if anyone else comes and reads this coming across the same issue we can see if we can put together a generalised solution

Sure. Should I reopen the issue or just leave it closed?
