I tried following this guide on the forums viewtopic.php?f=24&t=4880&p=44796#p44796 to get audio going on my virtual machine. I've gotten nowhere in this, unfortunately.
It seems like there's no audio codec based on the errors, but, I'm not sure where to go with this. I can actually find my audio device [1022:1457] in Ioregistryexplorer, but again, no idea what to do with this.
Hopefully the files attached should help.
