This week I had my HR24 swapped out for an HR44. I now have an intermittent issue of a 3-5 second audio drop when I switch tuners in DouplePlay or in PIP. It happens a majority of the time, but not always. It appears I can force the audio back with some trickplay commands, or it may just be popping back in automatically after a few seconds (hard to tell which). The issue doesn't seem to happen on channel changes, just on tuner swaps. The HR44 is using the same HDMI port and cable as my HR24 did, and it worked fine. The HDMI goes through my AVR, a Pioneer VSX-1020-K. I really don't want to change the way everything is connected. I've tried resetting the HR44 and I tried changing some handshake options in the Pioneer AVR, where I can select the signal to be 720, 1080, (etc) or Pure (it was set for Pure on the HR24 and worked well). I tried setting it to default from Pure to 1080, but this didn't help. Those were all suggestions I read on other threads with folks that had similar issues. Is this an HR44 firmware issue, a device issue, does anyone have a fix?
