Well... no sound! I've used "aplay" to test the S/PDIF output. The soundcard seems to work well, because the ampli recognize PCM / Digital, so I suppose the connection between PC and ampli is correct. So first I tried "aplay -Dhw:0,4" test.wav", but no sound. Then I've tried also "iec958" and "spdif", but nothing is outputted! Application work without reporting any error (only a warning if I'm not using a 48 kHz PCM, eliminable using "plug:iec958" as device). For the moment I haven't tried to use "iec958:0" as device because I don't have the amplifier to test audio. Any suggestion to know if any PCM data is outputted to a particoular device? My soundcard is a Realtek ALC850 (reported by alsamixer), and I'm using the intel8x0 ALSA module. I'm also programming a multimedia application, so I've tried to use the snd_pcm_iec958_open... I thought this was the solution! :-/ As I've understood, this plug (iec958) it's used automatically when I setup i linear PCM to the spdif device? While I have to create this plug (programming) whenever the soundcard can't do this task? About mixers (sorry for the stupid question, but for me it's quite new!): what mixers I should enable to output to digital? Thanks for all your help!
