Welcome to the new AT&T Community
We've got a fresh look! Take the tour to see what's new.
My U-verse VIP 2250 box is connected to an Onkyo HT-RC270 receiver (5 channel with sub woofer). I use an Infinity PS210 subwoofer. The subwoofer works fine with the PS3, the tuner, and the internet radio.
However with most U-verse TV stations there is a clipping sound and more recently a buzzing and clicking.
It is random and intermittent. The green light on back of the sub is on (most of the time i look) so it appears to get a signal.
I am trying to determine if the issue is the subwoofer or something else but it works fine with all inputs (same input cord) except U-verse.
Seems the trouble has worsened over the past months. I think it was present a bit before they changed my receiver (months ago).
Thoughts or tips on how to trouble shoot?
I rather not spend the money just yet to trouble shoot the subwoofer unless I can eliminate the U-verse signal.
You might want to check to make sure the audio on the receiver is set to "Surround Sound". Default is Stereo.

I have to other VIP 1200 units on bedrroom TVs.
Can i swap those to test?
(Not sure of difference but I know they do not have DVR)
How is the audio run from your STB to your AVR?
HDMI or Optical?
The cable is HMDI.
Oddly last night we played the PS3 game and I heard the clipping noise for a moment, then it went away after a few seconds. Later my son watched a movie (Movie Channel) and he said it worked fine with no "noise".
I may swap the box and see what happens.
I have read this Infinity PS210 is junk (lots of complaints) but just seems odd that when I hear the "noise" it is with the STB.
Lots of things can happen with subs.
Depending on age the caps can leak or dry out which can cause a hum or pop in some instances.
The cable connecting the sub could have a bad connection (wipe the ends down with contact cleaner and make sure it fits snug when plugged in) or it got damage physically look at the cable run.
Make sure your sub is getting an adequate signal if set to auto on not all sources output the same.
Sometimes re running room correction in the AVR or the test tone will show you what you need to know levels could be to high or too low.
I highly recomend this company . http://www.hsuresearch.com
I own the VTF-15H and it is all the sub I will ever need and HSU's customer service is second to none.
