I was under warranty but I did not want to eat the shipping change and be without my receiver for who knows how long.
I also thought it was pretty fishy that every other USB device worked fine--Apple was the only problem. To me, it smelled like a software problem, and I didn't really have any confidence that Onkyo could fix it. If the guy on the phone said, "oh yeah, I know exactly what that is," I would have sent it in... but since he didn't, I thought the odds of success were slim.
I decided to work around the problem and now I get my music a different way. If you are using an iPod, you probably have all your music in iTunes... maybe get a cheap AirPlay receiver and play music from the computer? It's not ideal if you want to use the iPod but ...
I actually did not try the rear port because the manual says that iPods can only use the front port, but I guess it can't hurt.
This was all in May of 2013, by the way.
OK I got my iPod out connected it with FRONT USB listening mode direct I'm happy to report no skips no pops listen to the Beatles across the universe, all was fine Jimmy Hendrix all along the watchtower all good, Angel Dave Matthews beautiful, as tears go by the stones nothing yet still playing very good, who do you love quicksilver messenger service thought I heard something but it was the source. I'm sorry didn't hear it on mine thank goodness sorry.
OK I just heard something where the streets have no name I heard a little pop a skip started it over seems to do it again, not sure what that is it almost seems the onkyo and Apple are not playing nicely not trying to be a conspirator hear but I do agree software issue is my guess.
Now I know what your talking about with the FRONT USB it sucks.
Ok I'm listen now through the AUX from my headphone jack and OMG THIS IS LIKE NIGHT AND DAY this sound 100% better the sound is what I expect these songs to sound like. I think that USB Port needs some kind of update.
Through the AUX no POPS SKIPS pure audio this thing sound great.... just get yourself a left and right Jack and plug it into AUX And then that into the head phone Jack on you iPod you will never go back to that USB Port.
I know this is not what you want to hear but that front USB does not play nice with my iPod
