Fons,
thanks for the suggestion, trying to explore it now:
resampler.cc:29:12: fatal error: pmmintrin.h: No such file or directory
# include <pmmintrin.h>
I have been testing on a pi4. Is there any hope of this stuff working there or do I need to move to an intel box? I don't know where the person I hope to help with this intends to deploy but it is more likely on the intel / x86 side of things.

As an alternative you could look at zita-jacktools:
class JackGainctl(JackClient):
"""
Multichannel dezippered audio gain control.
The 'gain' and 'mute' settings are independent. A gain
less than -120 dB is equivalent to 'off' (-inf dB).
The initial gain is 'off', not muted.
Gain changes are dezippered as follows:
'off' -> 'on' : 10 ms fade in.
'on' -> 'off' : 10 ms fade out.
otherwise : gain changes by max 6 dB for each 10 ms.
"""
or
class JackMatrix(JackClient):
"""
Audio matrix with gain and delay controls for each input,
output, and input-output pair.
Gains are linear and can be negative to invert a signal.
Use db2lin() to set gains in dB. Delays are in seconds.
Absolute gain values lower than 1e-15 are set to zero.
Gain and delay changes are crossfaded over one Jack period.
"""
With a few lines of Python you interface these to whatever
you need.
Ciao,
