9front on qemu with sound?

Hi, has anyone here made sound work on qemu with 9front as a guest with either a linux, windows or bsd host?

I have been trying it on a Linux (amd64) and windows host, each attempt has been the same, a plan 9 environment with no audio devices (nothing in '#A0' or no /dev/audio) 


Here is what I have tried so far. 

qemu-system-x86_64 -hda 9front.img  -boot d -vga std -m 768 -device sb16

qemu-system-x86_64 -hda 9front.img  -boot d -vga std -m 768 -device AC97

qemu-system-x86_64 -hda 9front.img -enable-kvm -boot d -vga std -m 2512 -cpu host -soundhw ac97

qemu-system-x86_64 -hda 9front.img -enable-kvm -boot d -vga std -m 2512 -cpu host -device intel-hda -device hda-duplex

None of these seem to error out, the guest still starts fine.  I have been testing ina live environment as well as an already installed environment, audio works on 9front if I run the OS on baremetal, though.


I realize this isn't exactly an important thing to get working, but I really want to.

I forgot to add.  when testing sb16, I did try adding this to plan9.ini
No luck. 



audio0=type=sb16 port=0x220 irq=5 dma=5

Some suggested I do -device sb16,audiodev=snd0
However, snd0 does not exist. Neither does any other value I tested (hda, snd1, sound1,sound2,sound3, pa,pa1,pa0, 1,2,3)

hda should be fixed in
http://code.9front.org/hg/plan9front/rev/0e47f4a0c4d6. could you build
a new kernel and try it? you should see a message like "#A0: codec #0,
vendor 1af40022, rev 00100101" on the console, and #A/audio should be
present and writable.

I didn't even manage to make sound work on qemu with linux or windows
as a guest.

I don't have any links on hand, but general discusstions online
suggest that qemu audio emulation sucks and you should just buy a
PCI audiocard, put it in your PC and configure PCI pass-through
instead.

that's a rather expensive idea. it works fine here.

I see. if I am going to do that I might as well buy hardware 9front and ethernet works on so that I don't need to use qemu

Thanks to a patch by mischief, it is now working with intel hda. http://code.9front.org/hg/plan9front/rev/0e47f4a0c4d6 
Thanks mischief!
