In fact on CPU's that support 64-bit, there will be no noticeable difference in CPU or RAM usage when using 64-bit samples on either a 32-bit or 64-bit kernel.
64-bit kernels will allow access to more RAM (which is doubtful you'll have) and may offer micro-optimizations because some 64-bit instructions are bit more efficient than 32-bit instructions. Those optimizations will be almost unmeasurable except in specific benchmarks.
It is very unlikely you will hear any SQ improvements. Given a certain audio file, renderers will have the exact same output on either 32-bit or 64-bit kernels. If there are any improvements, they will be side-effects in drivers that perhaps influence jitter. But it's very unlikely.
Thanks for the nice info regarding 64-bit :-)
Was it in this thread or another that volume glitches on Zero were mentioned? I also experience volume glitches and other audio glitches when using librespot + Multiroom. Maybe some sort of odd interaction between librespot ALSA API and the Loopback ALSA config for our Multiroom setup.
When I get some spare cycles I'll post an issue in your repo.
Ok after some testing It appears that our ALSA config for Multiroom is not optimal for librespot and can cause audio glitches. I do have a solution for this though :-) Also the stuttery volume change issue was due to a bug in our event script and has been resolved https://moodeaudio.org/forum/showthread....9#pid38499.
I'll plan to include both of these fixes in upcoming moOde 7.6.1 release.
