My goal is to get low latency audio working without passing through my audio interface.
- Ryzen 7600x
- Scarlett 2i2
- Pipewire 0.3.65
- Qemu 7.2.0
- LibVirtD 8.9.0
I have tried to use the built in spice audio in the B6 version with the
PIPEWIRE_LATENCY=512/192000 variable, resulting in the warning
PIPEWIRE_LATENCY value '512/192000' is invalid or does not match stream sample rate; using 2048/48000. I’ve set both in the commandline before looking-glass-client and inside of my xml file with:
<qemu:commandline> <qemu:env name='PIPEWIRE_RUNTIME_DIR' value='/run/user/1000'/> <qemu:env name='PIPEWIRE_LATENCY' value='512/192000'/> </qemu:commandline>
I then would manually set my pipewire latency with
pw-metadata -n settings 0 clock.force-rate 192000 resulting in it being pitched down, even if I restart the VM.
I have also tried to just use the raw jack audio and it’s not any better, leading me to believe it’s a failure on my part, but I am kinda out of ideas.
Is there anything else I’m missing I could try? I feel like the windows default audio driver might be stuck at 48k, but if I run reaper with asio it shows it’s using 192khz with 512 samples. Maybe even my interface isn’t playing at 192khz because it’s in a VM?
