Hi,
right at year end I ran into a serious problem on TW: Operating System: openSUSE Tumbleweed 20201228 KDE Plasma Version: 5.20.4 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2 Kernel Version: 5.10.1-1-default
In order to use an external monitor I used-prime select wo switch to nvidia - driver nvidia-glG05-460.27.04 (with just the intel driver, no expternal HDMI- Monitor can be connected).
Switch to external monitor worked well with everything, but suddenly sound is gone! Neither KDE audio module nor pavucontrol detect any sound devices anymore. Switched back to intel graphics, rebooted - no change,
Any ideas what to try?
Could it be that you're trying to use HDMI Audio? That would explain the bevaviour. By default suse-prime disabled HDMI audio in order to enable support for DynamicPowerManagement when using NVIDIA's PRIME Render Offload feature. You can get rid of DynamicPowerManagement manually by editing /etc/modprobe.d/09-nvidia-modprobe-pm-G05.conf comment out this one line in the file /usr/lib/udev/rules.d/90-nvidia-udev-pm-G05.rules comment out all the "ACION" lines More information on https://github.com/openSUSE/SUSEPrime https://download.nvidia.com/XFree86/Linux-x86_64/435.21/README/primerenderof...
