The host system is gentoo, using the ebuild for qemu 5.1.0-r2, and I'm using jack use flag globally in the system so any ebuild that have support for jack should be build with it. The jack setup reportedly works as I use it with firefox, and mumble with no trouble. When I launch the following script, I see the vm connects to jack: /usr/bin/qemu-system-x86_64 -enable-kvm -M q35 -vga virtio -display gtk,gl=on \ -cpu host -smp 2,cores=2,threads=1 \ -m 4G -L /usr/share/qemu \ -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1 \ -drive file=/usr/share/edk2-ovmf/OVMF_CODE.fd,if=pflash,format=raw,unit=0,readonly=on \ -drive file=debian_VARS.fd,if=pflash,format=raw,unit=1 \ -audiodev id=jack,driver=jack -device ich9-intel-hda -device hda-duplex,audiodev=jack \ -device virtio-serial-pci \ -device virtserialport,chardev=spicechannel0,name=com.redhat.spice.0 \ -chardev spicevmc,id=spicechannel0,name=vdagent \ -device nec-usb-xhci,id=usb \ -device usb-host,vendorid=0x04ca,productid=0x708e \ -device usb-host,vendorid=0x1050,productid=0x0407 \ -chardev spicevmc,name=usbredir,id=usbredirchardev1 \ -device usb-redir,chardev=usbredirchardev1,id=usbredirdev1 \ -chardev spicevmc,name=usbredir,id=usbredirchardev2 \ -device usb-redir,chardev=usbredirchardev2,id=usbredirdev2 \ -chardev spicevmc,name=usbredir,id=usbredirchardev3 \ -device usb-redir,chardev=usbredirchardev3,id=usbredirdev3 \ -netdev user,id=user.0 -device virtio-net-pci,netdev=user.0 \ -drive file=debian.qcow2,cache=none,aio=io_uring,if=virtio Output of vm initialization: jack: JACK output configured for 48000Hz (1024 samples) jack: JACK input configured for 48000Hz (1024 samples) gl_version 46 - core profile enabled GLSL feature level 430 Though executing any application that uses sound, for instance, any youtube video through browser, I listen nothing. By executing pkill jackd, and launching the same script replacing the audiodev line for the following: -audiodev id=alsa,driver=alsa -device ich9-intel-hda -device hda-duplex,audiodev=alsa \ The audio works, and I can listen to music, or any other kind of application, though I cannot listen anything else in the host. The guest is a simple debian testing(bullseye) system with plasma desktop, using pulseaudio, nothing fancy. Thanks!
