USB Sound Card 7.1 (Sound 5.1 doesn't work)

Help and Support Raspberry Pi

Hi, I have a USB Card for 5.1 sound. It doesn’t sound well with movies with 5.1 sound. The voices sound very very low. I have been trying in OSMC, but also in Windows and Ubuntu. In my laptop with Linux I discovered that Subwoofer and Center speakers were swapped. So, I swap these channels from:
/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf

It has worked on Ubuntu. But this conf file doesn’t exist on OSMC-Raspberry. I have installed pulseaudio and the file appeared, but 5.1 doesn’t still work.

Please, any help? Thanks.

Enable ‘boost center channel’ in Settings -> Audio.
