Bug description:
[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.
Tested patches in 1.0.5, confirmed it worked as expected. In my case,
the patches operated normally. Used build in PPA at
https://launchpad.net/~eeickmeyer/+archive/ubuntu/ppa
[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.
