 No signal at all from the SPDIF Toslink port! The reason trying this
pin is that when overridden, it shows "SPDIF Out".

 Ok, I deselected all other streams except PCM, no signal.. (Will do
this in future tests).

 I was able to run "aplay -Dspdif" without errors. I also checked in
another terminal if the alsamixer showed the s/pdif channels unmuted.
They are unmuted, but I didn't get a signal to my audio receiver. 

"aplay -Dspdif:1" didn't work: "Cannot find card".

iecset -x shows:

AES0=0x05,AES1=0x82,AES2=0x00,AES3=0x00
