Can you just move it up to e.g. line 173-ish and avoid that comment?

Sure. I thought it logically fit better with SetSendCodec, since they provide
the same type of functionality. This is a bit weird as well, though.

   void SetBitRate(int bitrate_bps, int64_t probing_interval_ms);
   int32_t SetVADStatus(bool enableVAD, ACMVADMode mode, bool disableDTX);
   int32_t GetVADStatus(bool& enabledVAD, ACMVADMode& mode, bool& disabledDTX);
