I have an AVR x1200w. Its the 2nd Denon receiver I've owned, and quite frankly my least favorite of the two. Snice the day I got it the Bluetooth as well as the front panel USB port have been iffy. Bluetooth wise, it forgets often what it was connected to last and the USB port sometimes just doesn't recognize anything is plugged into it. Like many other reviews I've seen, the only way to get the AVR to work properly is to disconnect power, reconnect and suddenly it all works until the next time it starts acting stupid again. \n\nThis past weekend I ran speaker cabling up through attic and over to my AVR to utilize Zone 2 on my patio. Man am I impressed with the sound of the Dayton audio speakers I installed. But....this AVR's Bluetooth is awful. and the Denon remote app...wow, its so bad.\n\nSunday I managed to get the app to work the majority of the day since we were outside a lot. But just like its always done...I go to use it today, app doesn't see the receiver. It sees other pieces of equipment, but not the receiver. I can get my phone and the AVR pair'd, but when I go to the app, it doesn't see the AVR at all. I have deleted and installed the app probably 10 times, I've re-paired probably 20 times, I've rebooted my phone repeatedly...nothing. Which really sucks because I don't wanna have to try and get the Denon remote to work through our back window to skip forward a song, or change volume. I don't know what my options are, but it would be nice to be able to use the app on my phone. I looked at the HEOS app (which seems to be more stable), but I guess in order to use HEOS, you have to have HEOS equipment. I "think" my receiver is HEOS able, but it requires an additional piece of equipment or something. I did download the HEOS app and it also didn't recognize my AVR. My question regarding this long story is...is there some sort of generic app that can be utilized with the Denon AVR to give me control from a device other than the Denon remote? I'm not interested in adding anymore hardware like Apple TV or any of that. I'm just wondering, is the Denon line of apps my only option? They all seem to suck.
