Use IC from another manufacturer, there can be quite a difference.

Make sure it is the same version.

If it says 74HC04 than use that and not 74LS04

You'll have to explain a bit better.

Also, do not expect wonders from this circuit.

You'll get some audio, but it'll be far from brilliant.

1.) Well, avoid doing this kind of stuff the last day for obvious reasons.

2.) Try something like this:

It seems to me that you might not be up to the projects you've
tried to accomplish.

I'm just saying that this is not over-the-night thing.

You've got a lot to learn. So if you're really into it, start
reading. Arrl handbook is one of the good sources to start
with. Check the recommended reading section for some tips.
