I tried with option

-ao alsa:pcm=default#ac3=iec958# -ao alsa:pcm=default#ac3=spdif#

Still get the error

ac3play: Unable to update the IEC958 control: No such file or directory

I have got softdevice working with sound via SPDIF for PCM, but cant get AC3 to pass through to the decoder, mplayer and ac3dec both pass AC3 no problem, but with softdevice I get error:

ac3play: Unable to update the IEC958 control: No such file or directory

-P"softdevice -vo dfb: -ao alsa:pcm=default#ac3=hw:0,0#" -P"softdevice -vo dfb: -ao alsa:pcm=default#ac3=hw:0,1#" -P"softdevice -vo dfb: -ao alsa:pcm=default#ac3=plug:iec958#"

I use : -ao alsa:pcm=default#ac3=spdif#

I think you're not that off : just remove "plug:" from the last one, to get "ac3=iec958"

Actually, I've got

softdevice -ao alsa:pcm=plug:spdif#ac3=plug:spdif# -vo dfb:

here. Works like a charm. PCM and AC3 get routed through the SPDIF out to my DD receiver.

Whatever ALSA devices you use should be mentioned by `aplay -L` :-)
