Public bug reported: Hello,
This is on Arch-linux(latest) and the qemu 4.2.0 version made from git clone https://github.com/spheenik/qemu.git with: ./configure --prefix=/opt/qemu-test --python=/usr/bin/python2 --target-list=x86_64-softmmu --audio-drv-list=pa --disable-werror added to the build. I've been workin on a passthrough Windows 10 vm this month and have been steadily seeing some promising progress. My block/issue at the moment is integrating the audio now that the GPU has been succesfully passed through. I've been going back and forth between the audio options for Pulseaudio and cannot change the following issue: pulseaudio: pa_context_connect() failed pulseaudio: Reason: Connection refused pulseaudio: Failed to initialize PA contextlibusb: error [udev_hotplug_event] ignoring udev action bind I leave my current operable build followed by some of the options that I have tried using to correct this despite the following errors not changing This is my current operable build: #!/bin/bash vmname="windows10vm" if ps -ef | grep /opt/qemu-test/bin/qemu-system-x86_64 | grep -q multifunction=on; then echo "A passthrough VM is already running." & exit 1 else /opt/qemu-test/bin/qemu-system-x86_64 \ -m 12G \ -drive id=disk0,if=virtio,cache=none,format=raw,file=.../win2.img \ -drive file=.../Win10_1909_English_x64.iso,index=1,media=cdrom \ -drive file=.../virtio-win-0.1.171.iso,index=2,media=cdrom \ -boot order=dc \ -bios /usr/share/ovmf/x64/OVMF_CODE.fd \ -name $vmname,process=$vmname \ -machine type=q35,accel=kvm,vmport=off \ -cpu host,kvm=off \ -smp 3,sockets=1,cores=3,threads=1 \ -device virtio-balloon \ -rtc clock=host,base=localtime \ -vga none \ -nographic \ -serial none \ -parallel none \ -soundhw hda \ -usb \ -device usb-host,vendorid=...,productid=... \ -device usb-host,vendorid=...,productid=... \ -device usb-host,vendorid=...,productid=... \ -device vfio-pci,host=...,multifunction=on \ -device vfio-pci,host=... \ -device e1000,netdev=net0 \ -netdev user,id=net0,hostfwd=tcp::...-:22 \ Here's a list of setting combinations I had tried to resolve this: #export QEMU_AUDIO_DRV=pa #QEMU_ALSA_DAC_BUFFER_SIZE=512 QEMU_ALSA_DAC_PERIOD_SIZE=170 #export QEMU_PA_SAMPLES=8192 #export QEMU_AUDIO_TIMER_PERIOD=99 #export QEMU_PA_SERVER=/run/user/1000/pulse/native #export QEMU_PA_SINK=alsa_output.usb-C-Media_Electronics_Inc._USB_Audio_Device-00.analog-stereo #export QEMU_PA_SOURCE=input -audiodev pa,id=pa1,server=server=/run/user/1000/pulse/native At best I have removed an XDG_RUNTIME_DIR error but other than that this build has no audio compatability. ** Affects: qemu Importance: Undecided Status: New ** Tags: builds -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1862887 Title: qemu does not load pulseaudio modules properly Status in QEMU: New Bug description: Hello, This is on Arch-linux(latest) and the qemu 4.2.0 version made from git clone https://github.com/spheenik/qemu.git with: ./configure --prefix=/opt/qemu-test --python=/usr/bin/python2 --target-list=x86_64-softmmu --audio-drv-list=pa --disable-werror added to the build.
