Hello,
Connected my Headphone and played and video online from one of the Appvms, the volume is too low, I opened the sound panel and switched all volume bars to max, yet is the same, any idea?
Any clue?
Qubes OS 4.3
Turn up volume on output device?
Yes, I did that, and test both volume levels on TV “HDMI” and Headphone “USB”.
Are you using sys-audio? in that case open a terminal and run alsamixer then F6, select your headphone and max-up volume. I recommend you to install easyeffects you will love it.
Thanks for the tip @Yjd6Zwb8 
, I’ll keep that in mind when I do the Sys-audio, for now, I’m using the OS as it is.
@Quber26 Open pavucontrol in dom0 (might be installed by default, if not, do sudo qubes-dom0-update pavucontrol to install it), go to the Configuration tab and switch the sound profiles for your USB headphones around. I’ve had good results going from Digital Output to Analog Output profiles or back. Pro Audio may also work, but it can be slightly complicated.
Just tried this now and nothing, even if i switch the volume all the way to 0, still playing, now the volume is like locked at a precentage and not going up and down, tried them all.
