The previous code is only correct if `bytesPerFrame` is a power of two. If it's not (e.g. 2-channel 24-bit = 6 bytes per frame), then the computed buffer position is corrupted. This can lead the code to use the wrong buffer half, resulting in glitchy audio. Fixes PortAudio#763

Thanks for tracking this down. Great to have our WDM/KS support inch closer to solidity. I'll wait for Phil's review before merging. |
