If I open a folder in caja containing videos and I play one of them using regular user and celluloid, volume knob on my keyboard works fine. But if I then open any other video from an "Open as administrator" caja window, it will not play any sound(based on my non-expert status I can only assume that this happens because root space and user space do not share the same default audio settings??) First question/problem/request: just like when applying monitor resolution changes into Control Center and applying them system wide, can you also please make it the same for the audio hardware output? As from a user perspective, it makes no sense at all to segregate the hardware values for sound when jumping in root in Ubuntu. Now my real problem is if/when I close my caja window that is in priviledge mode and I then re-open a video w/ celluloid with my regular user, sounds of course works fine, but my keyboard volume knob isn't responding anymore even though I see the volume on screen going up and down when I scroll it, the sound waves do not actually increase nor decrease. Some full moons ago, I posted something on UM forum which related of something similiar and here it is as a FYI: https://ubuntu- mate.community/t/19-10-problem-with-my-sound/20338/3 Furthermore, and again only as a FYI, I have blacklisted "hdi" and "snd_hda_codec_hdmi" in /etc/modprobe.d/snd-blacklist.conf and have rebooted my system to take effect. Hence maybe when you will try reproducing this you will also need to blacklist those 2 modules to get this volume control on your keyboard not listening... And while you have your hands into the audio code, and as of why I had to blacklist hdi, here's another FYI: https://ubuntu- mate.community/t/20-04-the-year-is-2020-and-still-nobody-cares-for- you-usb-hid-v81-11-gamepad/22530 Thanks!
