[alsa-devel] SPDIF: How to play mono sound

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
