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.
Thanks and Regards,
Ajay

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
Pavel.

Thanks Pavel,
It worked, just little improvement
it should be in quotes like this
aplay -D"plug:'iec958:CARD=ICH6,DEV=0'" mono_music.wav
Best Regards,
Ajay
