For this we need to know which bugs are still valid and which could be closed already. Thus we are setting the bug state to "Incomplete" now. If the bug has already been fixed in the latest upstream version of QEMU, then please close this ticket as "Fix released". If it is not fixed yet and you think that this bug report here is still valid, then you have two options: 1) If you already have an account on gitlab.com, please open a new ticket for this problem in our new tracker here: https://gitlab.com/qemu-project/qemu/-/issues and then close this ticket here on Launchpad (or let it expire auto- matically after 60 days). Please mention the URL of this bug ticket on Launchpad in the new ticket on GitLab. 2) If you don't have an account on gitlab.com and don't intend to get one, but still would like to keep this ticket opened, then please switch the state back to "New" or "Confirmed" within the next 60 days (other- wise it will get closed as "Expired"). We will then eventually migrate the ticket automatically to the new system (but you won't be the reporter of the bug in the new system and thus you won't get notified on changes anymore). Thank you and sorry for the inconvenience. ** Changed in: qemu Status: New =3D> Incomplete -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1906184 Title: Lots of stuttering/crackling in guest sound Status in QEMU: Incomplete Bug description: When listening to music (e.g. with VLC) or watching Youtube on the guest, there's lots of stuttering and crackling in the sound. = Tested with the following QEMU start commands: qemu-system-x86_64 -enable-kvm -m 6G -cpu host -smp 3 -cdrom ./linux/kubuntu-20.04-desktop-amd64.iso -boot d -vga virtio -soundhw hda -display sdl,gl=3Don qemu-system-x86_64 -enable-kvm -m 6G -cpu host -smp 3 -cdrom ./linux/kubuntu-20.04-desktop-amd64.iso -boot d -vga qxl -soundhw hda -display sdl qemu-system-x86_64 -enable-kvm -m 6G -cpu host -smp 3 -cdrom ./linux/kubuntu-20.04-desktop-amd64.iso -boot d -vga qxl -soundhw hda -display gtk = If I use the following command (QXL graphics, "remote" access via SPICE o= ver unix socket), stuttering is not completely gone but MUCH less annoying: qemu-system-x86_64 -enable-kvm -m 6G -cpu host -smp 3 -cdrom ./linux/kubuntu-20.04-desktop-amd64.iso -boot d -soundhw hda -vga qxl -device virtio-serial-pci -device virtserialport,chardev=3Dspicechannel0,name=3Dcom.redhat.spice.0 -chardev spicevmc,id=3Dspicechannel0,name=3Dvdagent -spice unix,addr=3D/tmp/vm_spice.socket,disable-ticketing and this command for accessing the VM: remote-viewer spice+unix:///tmp/vm_spice.socket = Guest: Kubuntu 20.04 64-bit (live), but occurs with many other as well Host: Arch Linux, with KDE desktop CPU: Intel Xeon E3-1230v2 (4 cores + hyperthreading) RAM: 16 GB GPU: Nvidia GTX 980 Ti To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1906184/+subscriptions
