Re: [Qemu-devel] What is the status of the QEMU sound rework?

Code is here:
https://www.kraxel.org/cgit/qemu/log/?h=testing/audio.gsoc

Merge was blocked back then due to depending on a QAPI updates.  Those
QAPI updates are merged meanwhile, even though it took quite a while
(merged late 2016 IIRC).

So, this series basically needs a rebase.  I suspect that is a multi-
week project minimum.  May well expand to be multiple months.  Which
leads us to ...

... this one.  But no student was interested in this project.

Fundamental issue is that right now there is not really someone paying
attention to audio in qemu.

I'm currently the maintainer, but due to also being busy with other
stuff I hardly find time to do anything beyond picking up fixes from
the mailing list, maybe do some basic testing (depending on the kind of
patches) and do a audio pull request now and then.

I suspect the problems are more in the qemu audio backends.  The issues
seem to be different depending on which backend you use.  So creating a
paravirtual sound card may not be the solution for that problem ...
