Sound Tweak Rpi4

[Tim Curtis]

Not "advanced tweaks" but "reasonable set of options". There's some things already in moOde for "tuning and experimenting" including the cpu governor, 32/64 bit kernel and mpd git compiles. Maybe thats enough but it would be interesting to hear what people think would be useful and most importantly why.

Most of the tweaks were essentially to reduce latency but the 64-bit kernel already does that to a greater degree. They might still have some merit especially on 32-bit.

Kind of related (tweaks is tweaks, right?) if mpd ever implements Sox recipes that could be a cool addition but it’s a really old entry so don’t hold your breath.

ETA with the play from ram talk that reminds me of the new input_cache directive.

Is there really a latency issue ;-)

@bitlab has some nice patches for MPD that improve the sample rate options that could be offered in moOde. I normally stick with stock MPD and don't do any patches but these could be very useful and so on the TODO list :-)

Ya, the input_cache option works well in 0.22-git. I'll definitely include it for robustness.
