Unwanted downsampling, on [internet] radio only

This seems to be fine:

ACC MP3 lossy output 24bit

Once audio has undergone lossy encoding, it no longer has an inherent bit depth. The encoded bits can be thought of as a mathematical description of how to reconstruct an approximation of the waveform that went into the encoder. The decoder usually calculates the reconstruction using floating point or integer math with at least 24 bits of precision. We chose to output 24-bit PCM in order to avoid introducing unnecessary dither to the decoded audio. Dither is basically a necessity when dropping a…

The reported source bit-depth might be just moot:

Live Radio bit rates being misreported?

Every station I click on and interrogate signal path states the stream is 24-bit - I think that would be unlikely
