In the command remove
-soundhw hda
which is redundant with
-device intel-hda -device hda-duplex
and probaly repcace
--audiodev pa
by:
--audiodev=pahowever, maybe this whole stuff is not necessary:-audiodev 
pa,id=pa,out.mixing-engine=off,out.latency=20000
I don't have it.

Maybe the kernel you are running in Fedora, Arch or Ubuntu does not have a
proper configuration for KVM, read:
https://www.linux-kvm.org/page/Tuning_Kernel

In Slint the kernel configuration is found in one of these files:
/boot/config-generic-5.14.14.x64
/boot/config-generic-5.14.13
These commands:
cat /proc/cmdline
uname -r
tell you which kernel is running, so you know how it is configured.

Also, there could be an issue with your qemu version.

In Slint at time of writing:
dance[~]$ qemu-system-x86_64 --version
QEMU emulator version 6.0.0
