Public bug reported:
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=on
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 over 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=spicechannel0,name=com.redhat.spice.0 -chardev
spicevmc,id=spicechannel0,name=vdagent -spice
unix,addr=/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

The QEMU project is currently moving its bug tracking to another system.
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.
