[Alsa-user] splitting a 4 channel usb sound card into master and headphone

[Samuel N. <nic...@gm...>]

Hi,

I have a Pioneer DDJ-WeGO, 4 channel USB device that outputs stereo
master and stereo headphone.
I've been scouring the internet trying to find out how I can possibly
split up the ports as it presents as a surround 4.0 device.

So far I've come up with nothing except an remapping in pulseaudio
that is super ugly to use.
I really would like to solve this at the lowest possible layer.

U have udev rules to discriminate the device working fine.

Is there any way to do this with alsa?

Cheers for any help,
Samuel.
