Nope. I use just single digital output. I admit I am getting lost in
this since DVB-S MPEG sound plays always (both with ALSA:digital and
ALSA:spdif) but AC3 plays only with ALSA:spdif while MP3 plays only with

I don't know how the IEC958 works in reality but it looks like I am just
a small step from a fully working solution. If the AC3 passthrough was
going to ALSA:spdif everytime and I could have ALSA:digital for other
sources *maybe* it would work.
