I dont think its as simple as this. Only the SILK parts of the audio are
automatically resampled, the CELT parts are always decoded to 48kHz. Just
changing the samplerate would then cause corrupted audio.

Personally I'm wouldn't like forcing a resampling of all audio anyway, Opus
as a format is specifically designed to not exactly preserve the input
sample rate, unlike other formats.
