Re: [LAU] Help with jack-volume please

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.

all the best,

drew
