Installed the PC version of Volumio, everything is up and looks great, however when I’m connecting the USB audio, i get a message “failed to open audio output”. The playback settings don’t show “USB Audio”, just “Audio”, not sure if it is important or not.
The same setup worked fine on a raspberry pi.
Hi, could you login (ctrl-F1 if you are in kiosk mode) and do aplay -l
sudo journalctl -b
and show us what you got?

After a few restarts I was able to hear sound coming out.
I then did the usual test, I turned off the USB DAC during playback and then started it again. No sound after that.
Audio was 96khz when working, after USB DAC reboot it was stuck on 48khz.
The commands you requested for did not change between modes.
volumio@volumio:~$ aplay -l

Hi, the commands were not supposed to change anything, just to show me what is happening on your machine.
The part I was interested in was the “journalctl -b” which you only showed the first page from.
Redirect it to a file and upload it please, without it I can only guess (and I’m not good at that).

@odedia,
just as a feedback. I looked at your logs and have not seen anything abnormal yet, but will continue…

Thank you.
I am uploading an updated log along with a sceenshot of what I’m seeing on screen. Note that I still have only one choice in the UI dropdown (“Audio”).
Thanks

Then Audio is your USB card, we can see it from the logs you posted.
Why are you turning off and on the USB DAC?
Just leave it on, and select audio…
I guess that’s a possibility… just feels pointless waste I guess. My DAC is rack-mounted and probably takes a good bit of power.
Regardless, this time audio didn’t work even though I booted the machine when the DAC was on.
Update: new DAC, still the same issue. Now I can just not get it to play at all (although in the past it worked occasionally with this DAC).
I think the problem is with volumio controls. I don’t have any volume control on my DAC (PS Audio Nuwave DSD), it is connected to a a preamp for volume. I also want to disable volume in volumio itself.
I am getting the errors below when selecting hardware or none volume control.
Try to select jack as output and save. Save mixer. Now select your dac and save. Save mixer.
