Sys-audio and Win(7) qube(s)

Thanks for your respomse as usual, @jevank
I must admit that after I found a way to passthrough audio device to sys-audio, it practically started to work out of a box for Linux qubes.

So as I just started to learn about audio virtualization, I couldn’t confirm that I understand everything is written on

When I run

[user@dom0 ~]$ sudo xl list

beside others, I’m getting

win7 23 3072 2 -b---- 653.7
win7-dm 24 144 1 -b---- 5823.0

So back to sys-audio, when I execute

sudo pacat-simple-vchan 23 win7

cursor just goes to next empty line and sits there blinking?

I have no idea what win7-dm is from above, though, but I tried the command against it, too, and I got response

Another instance of pacat-simple-vchan is already running for this VM (PID: 2368)

What should be the output of the command when working correctly?
When to run this command: win7 is off, running without music playing, running AND music playing?I

I see sound bars in win7’s mixer both in master and player bar, so it sends sound obviously.

If you don’t have time, some links to learn from would be good too!

Thanks in advance and keep up great doing!
