Use the amerge filter:

ffmpeg -i video_and_audio_input -i audio_input \
-filter_complex "[0:a][1:a]amerge=inputs=2[a]" -ac 2 \
-map 0:v -map "[a]" -c:v copy output

All inputs must have the same sample rate and format. If they are not, then use the aformat filter first.

If inputs do not have the same duration then output will stop with the shortest.
