[pulseaudio-discuss] how to pass correct channel map

[Vijendar Reddy Mukunda]

Hello,

I was just experimenting with a null sink.
I have created null sink with 48000Hz sample rate, s16le, channels as 6.
Tried to record from null sink monitor source.
But when i run parecord command, I am seeing the below error.
Warning: failed to write channel map to file.
I have also tried null sink creation
with channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe.
But no luck.
Need inputs on fixing this channel map issue.

Thanks,
Vijendar
