Hi i'm a Line 6 Pod HD 500 user from India and i've been having a lot of trouble with my HD 500 lately. The main problem is that from time to time the audio becomes garbled and almost bit-crushed similar to a ring modulated sound. This only started to happen recently and tends to happen while changing/saving presets on the HD Edit software and in some cases on the unit it self. It currently has the latest 2.02 flash firmware and the latest drivers are installed on my 64 bit Win 7 machine.

I tried reinstalling the firmware but since this problem started occuring i've never been able to update or reinstall or even roll back the flash firmware. It usually stalls and displays either "timed out waiting for response from the device" or "unkown hardware error" response. I've tried to update by going into the test mode but even that fails. But apart from this error windows recognises the device fine and line 6 Monkey and HD Edit recognise it as well.

I'm not sure if this is a software or a hardware problem and am considering returning and asking for a different model. I've had this for about 6-7 months but this problem only started about a month or so ago. If i can confirm that this is a problem specific to this particular unit i can try and return it.

I've opened a support ticket for this problem but haven't received a response yet so i've started this discussion hoping to receive some useful feedback from other HD 500 owners. If anyone has any suggestions i'd be very grateful. Thanks in advance.
