I managed to get GRC up.
But when I try to run an application that uses anything graphic, it
segfaults, and dumps core, from
deep within libdricore.so – related to OpenGL, I think?
So, rip out the GUI stuff.
Use my 4-channel audio-type SID receiver without any GUI goop:
Continuous aOaOaOaOaO until I interrupt it.
The audio_to_file.py example seems to work, though
