Public bug reported:
I have a dual screen set up, a Display Port Monitor and a HDMI monitor
on Ubuntu 18.04.1 ALSA driver k4.15.0-43-generic. The display port
monitor has speakers so I used as my main speakers, but, the audio of
any source sounds deeper/slower than it should be. Even videos of any
source last longer. For example, 10 "seconds" of any video in my
computer are 12.5 seconds in my phone stopwatch. I'm using a radeon r9
280x.
