Good diagnostics tool

For some time speakers on my HP nx7010 don't produce any output at all for unknown reason. So I decided to try HP diagnostics tool accessible from Help and Support item in Start menu. After some initialization I run Audio hardware diagnostics that looked like:

1. Run a short wav in player
   
2. Message box asked whether I hear sound from both speakers.
   
3. After clicking No the tool informed me (with both a red icon and text) that audio is not working.
   
4. No further steps are available.

Now, isn't that just lovely?
