format |= BCM2835_I2S_CH2(BCM2835_I2S_CHPOS(ch2pos));I can't understand how this works. We're programming the hardware in an identical fashion for both channel counts, that means that what we're sending will be indistinguishable from a garbled stereo stream. How does this produce working clocks or manage to sync up reliably with external clocks? -------------- next part -------------- A non-text attachment was scrubbed...
