Hi all, I have a pc with SPDIF out. I want to play audio file with single channel(mono) using aplay.
How to do that, when I try to play with following command, it gives error
aplay -Diec958:CARDICH6,DEV=0 mono_music.wav
it gives following error aplay: set_param:1065: Channels count not available.
How about
aplay -Dplug:iec958:CARDICH6,DEV=0 mono_music.wav
Spdif is a stereo device and does not accept a single channel stream. The plug plugin will do the conversion:
Plug PCM: Route conversion PCM (sformat=S16_LE) Transformation table: 0 <- 0 1 <- 0
