alsa-project/alsa-lib issue #482 was opened from Sameguyy:
```
$pactl list short sources
80 alsa_output.platform-snd_aloop.0.analog-stereo.monitor PipeWire s32le 2ch 48000Hz RUNNING
81 alsa_input.platform-snd_aloop.0.analog-stereo PipeWire s32le 2ch 48000Hz RUNNING
```
These are two interfaces that Pipewire automatically pulled in, and the sound goes into 3.0 and doesn't leave from 3.1
That is, I play a sound on hw:3.0 and when I try to read something from hw:3.1 I get silence
