Alphametric Puzzle: talk+talk+all=noise

Any Math genius:

I just cannot solve this Alpha-metric Puzzle:

talk

talk

__ all__

noise

where each letter represents a number from 1 to 9.

I think n must equal 1.

But each time I try, I get eight numbers (instead of nine), where one is repeated.

This is not for any math assignment— just curiosity.

Thank you,

Kierra

Talk+Talk+All=noise (puzzle solved)

I solved the puzzle myself .

I had a dream about what to do, and then I found the answer—easily.

Thank you all for trying.
