DScaler sound problem

Hello all,

Several days ago I've decided to try again this program - I found all the channels that I needed, with perfect picture - this software is really great! But I can not get the sound running. I know it is possible with my tuner - AverMedia 303, because I did last time(one or 2 years ago), but this time I can not find the way!
I've tried everything! If you have any ideas please tell me!

P.S. If you know another free software as DScaler feel free to tell it :)

Are you useing the latest Beta? v4.1.11

As for other progs.. do you want the De-interlace filter?

if not.. Media TV, Chris TV, and on......

I thought that I was using a stable release, but it is the beta 4.1.11
What do you recommend me? Shall I change it?
