I even tried installing a patch that was designed for the h3000 series iPaqs. It was intended to address issues where you'd hear a crackle noise at the end of a WAV file. It installed ok...but no success.

I was reading your other posts....sorry for all your bad luck. I would consider returning that unit. I know others have stated that they ended up getting a new unit with new problems. Please keep in mind, that in forums, people don't usually go out of their way to tell how great everything is working for them.
