Correction: I didn't explicitly try "desktop", because I thought it was 
the default. Well, it isn't, and if I select desktop I get an iec958 
digital output channel, but I don't get any output from the speakers, 
only from the headphones.
I looked into patch_analog.c and in patch_ad1884a I see that my laptop 
is detected as AD1884A_LAPTOP and it initializes some hp specific 
procedure to toggle the output between the speakers and the headphones, 
but unfortunately it also disables the digital output.
For the time being I commented out the line

   spec->multiout.dig_out_nit = 0;

and now I have sound through the speakers and I have the iec958 channel 
available.
Later I'll try if using that channel produces sound on the tv.

Bye
