On a fresh installation, in System settings > Audio I selected Profile: Analog Surround 5.1 Output.
If I hit Test and click every channel, they all work correctly except Subwoofer.
When I click Subwoofer no sound is heard, the settings application hangs for a while, and when it resumes there are 3 Playback Streams that never close, all called libcanberra:rear-center.
As a further test I ran
speaker-test -Dsurround51:SB -c6 and again no sound is heard for LFE, while all other channels work fine.
This setup was working correctly with other distros all using pulseaudio.
Is anyone aware of some channel mapping (or other) issue?
