Installed sys-audio, now no sound

[dispuser]

I use an external audio card that I plug into qubes.

Normal I will plug in audio card through the sys-usb and attach to VM so able to use.

Now I can’t do. I attach to sys-audio and open VM to play audio and hear nothing.

If I attach directly to VM then sys-audio just has dummy output and I hear nothing.

What do I doing wrong?

also i have two volume icons in the xfce panel one is sys-audio and one is pulse-audio panel, both show same icon. is this part of problem? regular pulse panel icon shows on and off, then “audio mixer” under that, sys-audio has drop down with many menu options including default server default sync and more

When I attach it, the input to the usb device shows up but the output doesn’t. The output is listed as a device but it isn’t showing as option for selecting for output of audio

this is too hard.

how do i uninstall sys-audio? extra security is not worth lack of usability

Are you able to play audio in sys-audio with your USB audio device attached to sys-audio?
You can try it by running this command in sys-audio terminal:

pw-play /usr/share/sounds/alsa/Front_Center.wav

If you attach your USB audio device to some other qube (not sys-audio) and try to play audio there then you won’t hear anything?

That’s normal, first one is for sys-audio and second one is for dom0.

Open the Volume Control window in sys-audio and make a screenshots of the tabs there to understand what do you see.

You can set the audiovm back to default instead of sys-audio:

qubes-prefs -D default_audiovm

Remove the qrexec policies and remove the sys-audio qube.

We actually don’t know anything about your sys-audio and if you searched forums and what did you try.

So, these might help

Setting up an audio VM

Out of the blue, totally new property might prevent you from hearing sound from sys-audio. admin.vm.property.Get +stubdom_xid sys-audio @tag:audiovm-sys-audio allow target=dom0

Guide on using an USB audio device with Qubes 4.1

https://www.reddit.com/r/Qubes/comments/tnib7k/guide_on_using_a_usb_audio_device_with_qubes_41/ I have bumped on this on r/Qubes yesterday. I’m still trying to make it work. I’m stuck at last command, because I don’t know the syntax of usb device name in it. That is why I didn’t put it to Guides. If someone is willing to try, it would be great to share findings. Please keep in mind that sys-audio that is mentioned there most probably is not not sys-audio in terms of Qubes 4.1

pw-play /usr/share/sounds/alsa/Front_Center.wav
bash: pw-play: command not found

I can attach the USB and hear audio now, but there’s nothing showing on the meter for sys-audio. It seems like sys-audio needs to use an internal audio device and can’t use an attached USB device.

You can try this one:

aplay /usr/share/sounds/alsa/Front_Center.wav

You can attach the USB device to sys-audio and hear sound from it when play audio in sys-audio?

Can you make a screenshots of the Playback, Output Devices and Configuration tabs in Volume Control in sys-audio when you connect USB device to it and you have some qube that have sys-audio as audiovm started after sys-audio as well?

Thanks for jumping in, because I was replied but it’s hard for me to help when I don’t know what steps I suggested were taken, and on which step hurdle was non-passable.

I can attach the usb audio device to a qube and hear from the usb audio device (which is external soundcard)

i do not hear it from sys-audio

does sys-audio need the device listed in devices attached to it? since the usb device can’t be on this list, sys-audio won’t work

[dispuser]

i also don’t know how to define sys-audio as the audio vm.

Sometimes I can’t shut sys-audio down because it says other Qubes are using it.

For the screen captures, I would needs to use dom0 for this and then copy images from dom0 to other Qubes to delete metadata and only show information about my system. I am still not familiar with cat commands. This will take me an extra hour I shouldn’t spend on this today.
