Help with OpusEnc (SOLVED - sort of)
...but somehow registers matching default values aren't re-written. I'm not sure where, (ALSA?) issues a chip software reset and then only programs the needed registers skipping one of the 2 registers for the PLL that generates the sampling clock. This results in the PLL generating a 1.5MHz BCLK/46.875KHz frame clock and not the desired 1.536MHz/48KHz clocks. So the resulting audio stream is short in samples over time every second. Now I just need to determine why/where the layer that's not writing BOTH PLL_D registers and fix it. Yay. But I thought I'd let you guys know this b...
