Bluetooth puzzle: pitch drops and tempo slows when connecting to bluetooth speaker

Pitch drops and tempo slows immediately when switching to bluetooth speaker.
Using a Mac M3, Bose SoudLink Mini bluetooth speakers. It’s a new problem. Only happens with Renoise, not when streaming audio or using other audio playback software.

sorry to bring this topic back to life, but Im having the same issue on my Macbook M1 Pro, does anyone know if theres a fix for this?

So the problem is resolved, but I’m not 100% sure why :grimacing:.

One clue came from this post and was supported by this post.

This seems to be the key idea:

I think my issue was that I was switching from non-bluetooth output to bluetooth output at an unsupported rate. (My bluetooth speaker does 44.1kHz only.) But who knows! Life is a mystery. :upside_down_face:

Indeed it is the sample rate, and also the codec

The earbuds I got are SBC and only support 48KHz, there’s also AAC and AptX which are higher quality and could support more sample rates, so check which one you’re using and if you can change it, I think some SBC devices are locked at 44.1 and others at 48
