Same problem as poster here. Not sure if I'm just not finding a similar thread here or if it doesn't exist. http://www.satelliteguys.us/threads/291245-AM21-audio-dropouts-with-HR34 Basically, tune an OTA channel with a AM21 hooked to a HR34 and eventually I get audio dropouts/skips and eventually no audio at all. Been this way the past few months, which is as long as I've had this combination connected. At this point I'm just wondering if it is worth swapping out the AM21 under the protection plan to see if it is something with my AM21. But, I don't recall having this issue hooked up to HR2x I used to have the AM21 hooked to.
