Arch thinks sound is working, but it's not (Guest in KVM / QEMU)

Hi chaps,

I have an Archlinux virtual machine running the very latest Arch-goodness.
It's running inside Kvm-Qemu on a Ubuntu system (don't hate me plz!! )

I have setup the sound to emulate an Intel AC97:

<sound model='ac97'/>

And when I load the Arch system and do a lsmod, it has loaded all the correct modules all by it's clever self:

The machine starts with every muted (possibly an indication that something is wrong?), but using

alsamixer

I turn everything up.
But when I try something like

aplay /usr/share/sounds/alsa/Front_Center.wav

I get no sound (and no errors).

I'm at a bit of a loss tbh; I have read and re-read the Alsa guide on your Wiki, but unfortunately it did not resolve the issue.

Would really appreciate some help please guys!
Thanks,
tommed

Is ac97 listed if you run this command (in ubuntu)?

qemu -soundhw ?

Are you using some sort of launcher? Afaik qemu doesn't use config files...

Have you tried playing sound as root? Just to rule out permission issues...

The sound is muted by default in Archlinux for some reason, so it's not an indication that something is wrong.

$ qemu -soundhw ?
Valid sound card names (comma separated):
pcspk       PC speaker
sb16        Creative Sound Blaster 16
ac97        Intel 82801AA AC97 Audio
es1370      ENSONIQ AudioPCI ES1370

Using KVM as the launcher (the

<sound .../>

snippet was in the KVM config file.

Thanks for the snippet about Arch starting with mute.. good to know!
