Thank you for bringing me on the right track! Due to my using an old
driver there is no "IEC958 Default PCM" switch, but a little research
discovered that you've dealt with this problem in February already (see
http://thread.gmane.org/gmane.linux.alsa.devel/50989/focus=51486 ), and
the proposed solution to set
	defaults.pcm.dmix.format S16
in ~/.asoundrc works for me.

I'm going to update the drivers anyways, but I'm confident that it will
work now :-)

Again, thank you for your quick response!
