MAC M1 with Funcube Pro+

[UncleBuck62]

I am just getting back into SDR after a long hiatus.

This is my set up... MAC M1 Studio running Sonoma Funcube Dongle Pro+

I am testing it with an AM Demod picking up a local radio station at 1422 KHz

SDRangel sees the Funcube but it will not run at a sample rate of anything above 96000. When running at 96000, the audio comes through but it is broken (pauses about every ¼ to ⅛ second) and what I do get sounds like chipmunks.

Have I missed something in the setup?
