Hello,
I’m trying to run a Rock6 9 guest OS using QEMU with a Mint 21 host machine.
Using various online resources here is the terminal command I’m using so far:
qemu-system-x86_64 -enable-kvm -boot d -drive file=rocky9_disk.img -m 8G -cpu host -smp 4 -vga virtio -display sdl,gl=on -audiodev pa,id=snd0 -device intel-hda -device hda-output,audiodev=snd0
Graphics performance is decent, however, if I maximise the QEMU window itself on my 1440p monitor, the audio falls to pieces (stutter, lag etc).
If I resize the window so it’s smaller, the problem goes to way.
I guess something is hitting a resource bottleneck somewhere but I have no experience in QEMU so I’m not sure how to diagnose issues like this?
My host machine is pretty powerful (5800x / 32gb ram) so that shouldn’t be the issue.
Has anyone got any suggestions please?
