[Alsa-user] Virtual device with conditional routing

[Frederik V. <fre...@go...>]

Hi,

I'd like to route the sound from a virtual device to two other
devices, depending on the number of audio channels of the input
stream.

Example:

if (channels > 2): send output to device pcm.surround
else: send output to device pcm.stereo


Is there a way to accomplish this task?


Best regards,
 Frederik
