3 weeks ago These findings are probably false positive, because TSAN does not understand PaUtil_FullMemoryBarrier(). However it is possible to anotate the code with __tsan_acquire, __tsan_release and firends to make it work.
Do you have interest to try it out? If it turns out that these are real issues. Mixxx will suffer them via Portausdio as well.
Bug Description
PaUtil_WriteRingBuffer / PaUtil_ReadRingBuffer
Fixed by replacing PaUtil ring buffer with a custom implrmentation. The PR needs some final polishing.
