Hello!
On Tumbleweed install alsa only! Pulseaudio removed. Using apulse for skype.

I have 1 soundcard (hw:0:0) and 1 webcamera with mic (hw:1:0) and in yast is selected as default (hw:0:0).
I'm using external mic (hw:0:0). Mic on web (hw:1:0) a'm not use, but it work if i specify in audacity capture device how hw:0:0 for external mic or hw:1:0 for mic on web.
With default and sysdefault playback devices all fine.
But capture default and sysdefault devices is mute or not set.
But if i specify capture devices in audacity how default or sysdefault, capture always mute (both microphones connected).
And also microphone always mute in firefox and chromium and telegram-desktop and this applicatons don't have config for specifying capture device.
I understand that they use the default device for both playback and capture.

How can I specify default and sysdefault capture devices as hw:0:0?
Or why is it always silent?
