[pulseaudio-discuss] Why I can't find multichannel-input and multichannel-output paths in path folder

[Chengyi Zhao]

Hi guys,

I have a computer with using Realtek ALC662 rev3,  it can adapt the 
multichannel profile below,

but I can't find multichannel-input and multichannel-output paths in 
path folder

(/usr/share/pulseaudio/alsa-mixer/paths), please tell me the working 
logic of

multi-channel profile, and how it differs from other profiles, thanks!

------------------------------------------------

[Mapping multichannel-output]
device-strings = hw:%f
channel-map = left,right,rear-left,rear-right
exact-channels = false
fallback = yes
priority = 1
direction = output
paths-output = multichannel-output

[Mapping multichannel-input]
device-strings = hw:%f
channel-map = left,right,rear-left,rear-right
exact-channels = false
fallback = yes
priority = 1
direction = input
paths-input = multichannel-input
