Fantastic, it works. But for clarification - why do I have to mute S/PDIF in alsamixer 
when in asound.conf I have already specified the stream from the virtual alsa devices to 
be sent to "plughw:0,0" which means the 1st card and the 1st device on that card, which 
is CX20561 Analog (CX20561 Digital is the 2nd device) according to aplay -l? I even 
have the default pcm and ctl interface set to the card 0 and if the device (and 
subdevice) are not specified alsa should automatically chose the 1st ones of that 
card...so why the hassle with alsamixer? Or if something's missing in my asound.conf 
can it be written there instead of doing it in the alsamixer?
