Onkyo 875 intermittent noise

[SkullPhyre]

I have had my receiver about 3 months. No problems. I did the DTS-MA bomb update about 2 weeks ago smooth sailing no issues. The last couple of days a weird noise has surfaced sounds like duh duh duh duh dut. Like when a cell phone is close to a pc and it is about to ring. Also my Ipod dock when a ipod is plugged into it the ipod screen light stays on for a couple of hours instead of turning off when it is set in the cradle.

This is my equipment list all hooked up with HDMI except the wii which is connected with composite. ( I don't play it the kids do and they can't tell the difference.)

PS3
X-box 360 w/ HDMI
Motorola Dvr hd cable box Model DCH3416
Wii
POS Sony dvd player DVP-NS700H
Onkyo DS-A2X Ipod dock

It just started doing this and it is random on all sources. Lasts for a few seconds then stops. Any help would be appreciated I sure hope I don't have to send it to Onkyo I will get it back months later.
