dialnorm_Maximum                         : -28 dB

Now I see correctly 8 clips on Audacity.
Which channels are they?
I mean, track 1 → L, track 2 → R, ecc

Where I can find info about DD+ 7.1 to solve my problem?

Thanks

I don’t know about 7.1 but I have it for 5.1 (from a test DVD):

1= Left
2= Right
3= Center
4= LFE
5= Left Surround
6= Right Surround
