Is the limit an ALSA one, or somewhere else in the chain?
It's the USB driver and DAC firmware.
Doing over/up/resampling, etc, isn't inherently difficult provided you have some filter values, etc, in mind. So an open source player doing this and tweakable by the user should be possible. Has no-one done anything like this for Linux?
Sox can; but that's command line. I haven't come across a player with a good GUI that enables you to manipulate the various parameters. Squeezelite allows some parameter setting using the sox library. Maybe other players do, but I haven't explored them.
