[FR] per-output profiles #825
Description
(maybe both default bluetooth and per-device bluetooth, same for usb and jack; and for jack user has to manually select non-default if he wants to?)
allow changing settings such as
- boost
- replaygain (pre amp/non rg gain/drc; not mode though)
- allow use of direct track, and maaaybe manual flag selector and bit format override
- allow boost despite absolute volume
- different dsp presets
- (for usb) allow use of bit perfect mixer behavior, or user space uac driver, or default
- "prefer internal resampler" checkbox which kicks in when mix port is different and device support or sample rate changer settings don't allow fixing that (off, or below minimum, or above maximum)
- (for usb) dsd-over-pcm checkbox
- (for later) noise shaping dither (off/24bit/16bit)
- (for usb/bluetooth/mtkhifi where we can change SR) sample rate changing on/off and upper limit (to prevent HR on bluetooth for example) and lower limit (if output has no integrated upsampling because its trash) - implicitly that also allows for fixed value (if SR change causes pops or delay)
(would bit depth change be useful as well? here i would just say auto/default or fixed value) - (for later) additional audio latency in ms (used for lyrics timing and maybe timestamps in UI), for devices which underreport it
