[Qemu-devel] QEMU being able to use audio cdroms

[Programmingkid]

Is there any platform where a guest in QEMU can play an audio cd? If not, is this a feature that you would allow into QEMU?

I haven't tested it, nobody has ever asked. I wouldn't reject patches
for such a feature, but I likely wouldn't make reviewing them a priority
either.

I assume this would be primarily for emulating games/etc that use mixed
Data/Audio formats?

That could be one reason to do it. I just thought it would be neat to be able to play CDs inside a guest.

Yeah, I saw a demo with cd-rom redirection working, but in an older
version of QEMU (1.7.2). It even has spice support.

Not sure what changes are necessary to make it work upstream.
You can check cdrom branches here [0]

CCing Marc-Andre that sent the patches and Pavel which was working on
rebasing this.

It might work if you use a SCSI controller and "-device scsi-generic".
At least I could burn CDs a few years ago.

Of course, the audio would come directly out of the computer speakers,
without going through QEMU's backends.
