A host at 12.10 and guest at 12.11 with GPU and its audio passed through to a VM. The video and audio show up fine in the VM, but are unresponsive to the system. The mixer icon shows muted, although alsamixer does default to the HDMI, all bars are lowest. I can run videos in Kodi but they are jerky and there is no sound. Def not using the Radeon.
I've read till my eyes bleed but nothing works. Zero errors in dmesg. Any ideas muchly appreciated. Here's some meat and potatoes: # dmesg ... 07:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
