problem with audio filter with sidechain

[geextahslex]

Hi, I try to make this audio filter chain to work and it "loads" but the audio is in a different position.
Does someone know how to fix that?

this is in mpv. using asplit to use the same input stream twice
af=lavfi="[aid1]dynaudnorm=p=0.50:m=2:f=100:g=15:s=30,asplit=2[a1][sc0];[sc0]highpass=f=2000[sc];[a1][sc]sidechaincompress=threshold=-35dB:ratio=4:attack=50:release=250:knee=6[final]"

this is working with ffmpeg, here you can just map the same input twice
-filter_complex "[0:a:0]dynaudnorm=p=0.50:m=2:f=100:g=15:s=30[a1];[0:a:0]dynaudnorm=p=0.50:m=2:f=100:g=15:s=30,highpass=f=2000[sc];[a1][sc]sidechaincompress=threshold=-35dB:ratio=4:attack=50:release=250:knee=6[final]"

Thanks for any help :)
