[pulseaudio-discuss] [PATCH] sink-input/source-output: Fix LFE remixing suddenly enabled

[David Henningsson]

Steps to reproduce:
 1) Leave LFE remixing disabled (the default)
 2) Start playback of stereo material on e g 5.1 surround, notice nothing in LFE
 3) Now change profile to e g 4.0 surround and then back to 5.1 surround
 4) Notice that LFE channel is now remixed
