Tuning window is blank with FlexRadio DAX drivers are installed #4

My tuning window is blank when FlexRadio DAX drivers are present on the system.

After removing SmartSDR and the DAX drivers, samples begin to be received (kmaudio_readsamples returns non-zero) and the program begins to work.

Win 10 x64, tried deleting the config directory, tried v0.87 and v0.89.

It seems that the large number of audio devices installed by FlexRadio's SmartSDR overruns the NUM_OF_PIPES available. Simply increasing NUM_OF_PIPES resolves the issue. This fix is present in my fork: https://github.com/M0LTE/AMSAT-DL-QO-100-Modem

M0LTE commented 1 year ago

This is resolved by commit https://github.com/M0LTE/AMSAT-DL-QO-100-Modem/commit/5bfdb4be9386254755afd95615d6ef6405dc0b24

My fork contains various other improvements too- primarily, hamlib PTT support. Feel free to merge any/all of it in to this repo.

See here for binaries.
