How do I change my PulseAudio settings?

PulseAudio has no default settings for surround sound support. To enable all channels, edit the file /etc/pulse/daemon. conf: uncomment default-sample-channels (ie remove the semicolon at the beginning of the line) and set it to 6 if you System 5.1 or 8, if your system is 7.1.

Why is PulseAudio using so much CPU?

The key insight here is that pulse’s job is to route, mix and resample audio from apps to the correct device. Different apps/devices may have different samplerates (e.g.: 44.1khz to 48khz) so pulse is resampling which will typically require a lot of cpu resources.
