If I understand ALSA correctly, not using dmix will cause sound-producing applications to grab the sound card exclusively if it doesn't support HW mixing. I would try it in any case, if only to eliminate problems on the host side.
System-wide ALSA config is /etc/asound.conf, user-specific is
~/.asoundrc. The syntax is not intuitive, to say the least.

Hi, I didn't have this issue, so here are my wild pointers :) Do you have pulseaudio on the host?
No I only use alsa and it is not installed.
Have you tried other soundhw models ("qemu-system-x86_64 -soundhw help" will tell you what's available).
Yes, I tried some and they did not fix the problem.
What does your .asoundrc look like? Do you use ALSA's dmix?
As far as I can see dmix should not be used. (I might miss something, but I could not find any '*asound*' on my drive. Not in /etc/ nor in my home directory. Also it is not shown when I type aplay -lL)
