I've my HDMI as main output (from the USBC port) for video / sound settings. No matter the volume as used, when I'm unplugged / replugged the volume is back to 100%. It's something since 6.2.X, on 6.1.X the volume was memorized and reused on unplugged. The laptop volume is kept like before. STEPS TO REPRODUCE 1. change the volume at 20% when your hdmi is connected 2. unplugged your HDMI 3. replugged your HDMI 4. your volume will return to 100% SOFTWARE/OS VERSIONS Operating System: KDE neon 6.2 KDE Plasma Version: 6.2.3 KDE Frameworks Version: 6.7.0 Qt Version: 6.8.0 Kernel Version: 6.8.0-48-generic (64-bit) Graphics Platform: Wayland Processors: 16 × 13th Gen Intel® Core™ i7-1360P Memory: 31,1 GiB of RAM Graphics Processor: Mesa Intel® Graphics Manufacturer: LG Electronics Product Name: 16Z90R-G.AD78F System Version: 0.1
