I had Directv installed at my house a week ago. I have the HS17, 1 wireless mini and 2 C61K boxes in my setup. I have an audio popping noise issue on both of the 61K clients. If you do the 30 second skip it pops when video resumes, changing channels will produce a popping sound sometimes, clicking and selecting a different channel in the guide will cause the same issue. It happens on both 4K boxes. One of them is connected into a Marantz SR8015 receiver and the other directly to a TV. Note the wireless mini doesn't exhibit this issue. The sfotware version on the 61K clients is 0x13f5. Anyone else have the audio popping issues? The popping only exists in above scenarios and not while watching content. I have called DTV support and they don't even know what version of software the 4K clients should be on. That is scary and lame. How can a support department not even know what the current version of software is? I do have a tech scheduled to come out here in a week. Thanks in advance for your feedback.
