Hello everyone!

I registered on the forum to ask a question and I thought I could attempt to contribute in some way instead of just pushing another discussion of the first page to make way for it. Sooo...

If you have a question that doesn't quite deserve a thread by itself feel free and post it here.

Good way to keep it nice and tidy. I'll start with my, oh so embarrassing, question...

I literally JUST downloaded a DAW, having never used one before so I am as green as they get and I've already run in to a bit of a problem.
There's no sound when I play my project back. There is when I'm previewing samples but after I started arranging them, trying to recreate a track, they don't make a noise when I hit the play button and the bar passes over them. Screenshot below.

This is some basic shit and probably super obvious but I can't see why haha, nothing is muted! Hopefully the screen shows what's wrong.

If you guys don't think one of these thread is necessary just let it pass through, thanks anyways!
