Having the volume set to anything but 100% causes noise to appear on playback. The channels affected depend on which channel has had its volume change, but with no obvious pattern. Upstream report: https://gitlab.freedesktop.org/pulseaudio/pulseaudio/issues/723 This is a regression between a fairly minor update: pulseaudio-12.2-6.fc30.x86_64 <= BAD pulseaudio-12.2-3.fc30.x86_64 <= GOOD I can't see anything in the changes that explains this. Build system changes that result in a bad build? This is HDMI output on a Ryzen APU (upstream report has lots of details in attachment).
Upstream suggests that this might have been triggered by an upgrade to gcc 9.1, which seems plausible given when that was built in koji. Patch for fix linked in the upstream report.
Build with upstream commit included underway, https://koji.fedoraproject.org/koji/taskinfo?taskID=37308796 Alternatively, can test latest pulseaudio-12.99.2 from our copr, https://copr.fedorainfracloud.org/coprs/rdieter/pulseaudio/
FEDORA-2019-e5b6f7abc2 has been submitted as an update to Fedora 30. https://bodhi.fedoraproject.org/updates/FEDORA-2019-e5b6f7abc2
I'm afraid you forgot to actually apply the patch. :) I did a manual fixed build here and can confirm that the issue is now gone. :)
Arg, I'm spoiled by using %autosetup macro *almost* everywhere (that automatically applies all patches).
