I just got off the phone after not talking with Dish since 7 Jan. I was told if the audio drop problem was not fixed by 1 Feb 2007, they would send out a 625. Oops, an employee error. Of course, I did not know the 625 has the same problem. So I will not push the 625 issue anymore.
The supervisor I spoke with told me Dish has no record of the audio drop problem. I replied with not so. I did ask the supervisor for a solution. He responded with sending out another 522. I said if the last three didn't solve the problem, I suspect the fourth one won't either. I told him my installation was still under warranty so what was the next alternative. He suggested sending out a tech. If that's your solution, let's do it. You're paying for it. I added if the audio drops after the tech does his work, I'll call back and you can send out another one in a week or two. I can do this for a while. We'll see what happens on Feb 10 while I'm sipping coffee.
I hope the tech brings out another 522. The hard drive has been banging non stop whether or not there is activity. It's not going to be long before this one fails. I will add the audio drop has been less frequent during the last month. It dropped once on the 28th and twice today. Maybe the engineers are working on the problem. Thanks to everyone for providing their experiences.
