Ah, I understand you now. No — cmus has no built-in general purpose resampling.

My quick googling tells me that jackd does not resample audio.
Resampling in the player seems to be the only option then.

As for resampling for other output plugins, I do not remember people
complaining about lack of builtin resampling in cmus. I think we can
leave that as is for now.
