[SOLVED] Qemu sound issues (probably drivers related)

xrld · 05-19-2021, 07:21 PM

Hello,

I successfully ran Windows 10 virtual machine using qemu (with kwm enabled), but I encountered some audio issues.

I searched for solutions and I found this note on archlinux wiki:

Quote:

Note: Video graphic card emulated drivers for the guest machine may also cause a problem with the sound quality. Test one by one to make it work. You can list possible options with qemu-system-x86_64 -h | grep vga.

I tried all of the listed options and I found that only using cirrus driver results in good audio quality. The same wiki says, though:

Quote:

The cirrus graphical adapter was the default before 2.2. It should not be used on modern systems.

Is there anything I can do to improve sound quality with other drivers (like vmware, virtio) or sticking to cirus is my only option?

Thanks for any reply.

You say sound then describe video.
Sound is a separate virtual device.

I think I'd be more inclined to run virtualbox and add in the tools to windows 10.

As I described before, I was suggested by this quote from archlinux wiki:

It seems that there is correlation between video driver and sound quality.

Fortunately I found that the issue was caused by the software I used in guest machine and the sound works relatively fine outside of it. I came here to explain that and solve this thread as solved.

Thank you for your response anyway.
