Audio issues when inputs have different frame (or sampling?) rates

[Kunsi]

When configuring voctomix with multiple audio inputs (or, if voctomix is running with blinder enabled) and those sources have different frame rates (or sample rates?), voctomix will produce "robot audio" after some runtime (>1h but <1d).

For now, we should advise users to run everything on the same frame rate for best results.

We have had no issues with inputs running on different frame rates if those inputs have no audio configured, only if the inputs have audio.
