Public bug reported: [Impact]
A regression in 1.0.5 has been found in PipeWire and is fixed in 1.0.7. Users of certain MIDI controllers that rely on long SysEx messages are unable to function properly. I noticed this when reconnecting my Beheringer X-Touch (shown here: https://nextcloud.ericheickmeyer.com/index.php/s/k9Aa9Bq7RDD5DoR) after the installation of 24.04 LTS, it could not operate properly. Disabling pipewire-jack and running ardour's internal jack functionality caused it to work properly. Investigation consisted of backporting 1.0.7 via a PPA to Noble which fixed the bug. Bug was confirmed via https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4005. Solving bug via SRU will consist of creating patches from the commits that fixed the issue in upstream PipeWire. [Test Case] Using Ubuntu Studio * Connect a MIDI controller that uses long SysEx messages, such as a Behringer X-Touch, to the system. * Star Ardour * In Preferences > Control Surfaces > Mackie, select the MIDI controller for "Surface sends via:" and "Surface receives via:". Expected: complete control population and function Actual: Only display colors are populated [What could go wrong] It is possible that these patches could cause other problems outside of long SysEx messages in MIDI controllers. However, these patches were developed by the lead developer of PipeWire, Wim Taymans, and I tend to trust that he knows exactly what he's doing with this kind of thing.
