or if you want a single audio stream with 5 channels:
ffmpeg -i HD422.mxf -i 8ch.wav -c:v copy -c:a pcm_s24le -filter_complex \
"[1:a]channelsplit=channel_layout=7.1[a0][a1][a2][a3][a4][a5][a6][a7],\
[a1][0:a:1][a0][0:a:0][0:a:2]amerge=inputs=5[a]" \
-map 0:v -map "[a]" -timecode 01:00:00:00
This works as intended:
ffmpeg -i HD422.mxf -i 8ch.wav -c:v copy -c:a pcm_s24le -filter_complex \
"[1:a]channelsplit=channel_layout=7.1[a0][a1][a2][a3][a4][a5][a6][a7]" \
-map 0:v -map "[a1]" -map 0:a:1 -map "[a0]" -map 0:a:0 -map 0:a:2 \
