* Optimized routine for mixing buffer with gain.
* This function may choose SSE over AVX if the pointers are
* aligned to 16 byte boundary instead of 32 byte boundary to
* reduce time to process.
* @param[in,out] dst Pointer to destination buffer, which
* gets updated.
* @param[in] src Pointer to source buffer (not updated).
* @param nframes Number of samples to process.
* @param gain Gain to apply.
