speed_set reinitializes the audio filter chain to adjust to the new sample rate.
If you give an example of the exact filter chain (or better full command line)
and audio output you are using, there's a better chance someone can take a look
and tell you what goes on.
Maybe you are doing things in a way that results in a sample rate change in
the audio output: then the behaviour would be unsurprising.
Maybe you are already using a resampler to ensure the final rate stays the same,
in that case maybe there's just some logic missing to prevent the rest of the
filter chain from being re-initialized etc.
