Thank you! That solved the syntax problem. The final audio parameters I'm using 
are:

-device intel-hda -device hda-duplex,audiodev=snd0 -audiodev 
alsa,id=snd0,out.dev=hw:Loopback,,0,,4,in.dev=hw:Loopback,,1,,5

For some reason the sounds do not still work, though. But at least the virtual 
machine starts and kind of thinks it has a working sound card (until actually 
trying to use it). This is now some other problem I guess.
