I can't find any fix that exists upstream yet. It sounds like Red Hat just reverted the problematic commit.
If you can't find out where an upstream fix exists (in git.kernel.org) then please start by creating an upstream bug report for it here: https://bugzilla.kernel.org/enter_bug.cgi?product=Drivers&component=Bluetooth And then let us know here what the ID of the new bug is. ** Changed in: bluez (Ubuntu) Status: Triaged => Incomplete ** Changed in: bluez (Ubuntu) Assignee: Daniel van Vugt (vanvugt) => (unassigned) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1759628 Title: bluez regression: Bluetooth audio fails to reconnect after resume Status in bluez package in Ubuntu: Incomplete Status in bluez package in Fedora: Fix Released Status in Suse: Fix Released Bug description: STEPS TO REPRODUCE: 1.
