Hello All,
Late last year I spent a lot of time trying to get OB working on a pair of Raspberry Pi3s.
I communicated with you all on the list to try to get by the “My Mono Problem” I was
having and eventually gave up. I'm back now trying again to get this to work for a
community radio station (KBOO) backup STL that’s really needed. My configuration is:
Raspberry Pi3B+, Behringer UCA202, OB V4.0.3 running under the current version of
Raspberry Pi OS (32-bit) Lite, Kernel Version 4.19. This time I have had a bit more
success in that I have been able to get a stereo link established by running the
transmitter in PCM mode. However, when I try to use OPUS encoding the link is established
but it is again in mono.
How can I get a stereo link using OPUS encoding? Help please!
Thanks,
Phil
