"No" errors? This works for me (9 inputs): $ ffmpeg -f lavfi -i anoisesrc=seed=0 -f lavfi -i anoisesrc=seed=1 -f lavfi -i anoisesrc=seed=2 -f lavfi -i anoisesrc=seed=3 -f lavfi -i anoisesrc=seed=4 -f lavfi -i anoisesrc=seed=5 -f lavfi -i anoisesrc=seed=6 -f lavfi -i anoisesrc=seed=7 -f lavfi -i anoisesrc=seed=8 -filter_complex 'amerge=inputs=9,pan=mono|c0=c0+c1,volumedetect' -t 5 -f null - (volumedetect is there to verify that it is not silent.) What are you trying to achieve with amix?
