I had to soundcards for months if not years. Suddenly both of them have quit working with my handheld microphones.


I thought it was a case of a malfunction. Andrea support sent me a new soundcard. Right out of the box, it did not work with either of those two microphones. I plugged an ATHCOM-1 headset in and everything worked just fine.


I'm completely confused. I suppose it could be the microphones or the cords used to connect the microphones to the soundcards.


But I used everything in both configurations for a while, and for couple of months, everything worked just fine.


Any advice or thoughts would be greatly appreciated.

It looks like your computer and USB soundcards are fine; as proven by your ATHCOM-1 analog microphone. Can you tell us what you are using for handheld microphones? It looks like they both have an issue but they shouldn't have a simultaneous issue

That has already been answered in the original subtitle to the thread.

I have never had an Andrea soundcard become defective. They typically last for years and years without problems. I have one that is more than 15 years old, and it works perfectly. If your handheld microphones have suddenly and unexpectedly stopped working, I suspect it might be a problem with your settings. Even though we can use multiple and different microphones on one profile, it might be worth checking out. Also, it is not normal for a handheld microphone to have a wiring problem that affects them.  I interchange my handhelds, dependant upon the high noise background of my working environment from a Microtech Gefell 300 to a Sennheiser MD 431, without problems.
