Hey @jacobacci, - Thanks for the interest!
cdspeedctl is already in active development and being prepared as part of the Volumio 4 (Bookworm) Beta integration. The initial rollout will target Bookworm-based systems only, since it depends on newer system libraries and updated kernel behavior not present in Volumio 3 (Buster).
There is no ETA, but the prototype is functional and undergoing testing across multiple architectures (x86_64, ARMv6/v7/64). Once validated, it will be integrated into Volumio 4 as a low-level service to ensure quiet CD playback out-of-the-box, without manual eject -x scripting.
I don’t expect it to be backported to Volumio 3 due to architectural differences and end-of-life status of the base OS.
Kind Regards
