Hello, I've been using Opus on an STM32 M4 platform for speech coding in mono mode. I thought I'd try stereo for grins to see if I can handle the CPU load, and I'm getting a return code of -1 from opus_decode_float (using CBR and 40ms frames). I decided to try the opusenc and opusdec tools to just see how the command line apps would behave. I am getting decoded audio, but I am

...h part at 8kbps CBR. Or, there may be a magic "enforce 100% stereo" one could pass?

I'm running Opus (both encoder and decoder) on a Cortex-M7 (using floating point), and am getting an audible artifact each time I call the decoder with a NULL for the input data pointer. Normal encoding/decoding sounds fine, but when I run a test where I pass in a NULL on every 20th frame, I can hear what sounds like a quieting of the background noise and an impure tone (each time at a
