Allow JACK access from inside sandbox #14

Closed ssssam closed 4 years ago

ssssam commented 4 years ago

Since Flatpak 1.6.1 apps can request access to /dev/shm, which allows them to connect to a JACK daemon outside the sandbox. See https://github.com/flatpak/flatpak/issues/1509 for details.

This nay provide a better experience than the current hack of using padsp and the OSS backend, which can suffer latency due to going via PulseAudio and has a lockup bug too.

The JACK access is totally unsandboxed. We should switch to using Pipewire as soon as that becomes practical.

This is not actually possible, as explained here: https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/issues/1001#note_323464727
