    Shortly after setting up my new Pioneer 45TX, my wife was watching TV/SAT. I wasn't home at the time, but she described it as "chirping sound coming from the speakers". Now before you think it's a problem with the receiver, get this....the power was off. First let me explain how everything is hooked up.

    SAT(Dishnetwork PVR-501)-> TV via composite & L/R audio
    -> RCVR via opt. dig. & S-video
    RCVR L/R Front pre-out -> Onkyo Integra ADM 2.1 amp

    I'm running the fronts off the amp because the speaker cable is not long enough to reach the RCVR. I'm waiting for new cable to arrive. The 45TX can do multi-room/multi-source with the unit off. Having said that, the sound isn't there when the unit is on. It correspondes to using the remote. Press volume on remote, speakers chirp faintly. Change channels, slightly different chirping. It seems to do it worse with the SAT remote than any others. I haven't been able to test if the speakers will do it if hooked up to the RCVR yet. So, anyone have any ideas or noticed similar noises from their units? Let me know what you think. Thanks.

    Tim,
    I have a VSX-45TX and as far as my satellite reciever goes it's connected similarly to yours:

    Toshiba DST-3000 HD ready DirecTV receiver video direct to tv via component and S-video with analog L and R audio direct to tv. Digital audio out from DST-3000 via optical cable to VSX-45TX. No video from DST-3000 running thru receiver.

    This was so I could watch satellite tv without having to fire up the receiver.

    I have no external amplification however.

    With the receiver in standby (turned off but single red led on) I get no chirping when changing channels with the DirecTV receiver remote or when doing anything else with any other remote.

    Hope this helps.

    I would start by unhooking the amplifier and see if it stops. That would isolate your problem. If it is the reciever it would stop. If it was the Onkyo amp it would probably keep going. It could also be something in the cable picking this up.

    I would guess that what you are hearing is one of the amplifiers somehow picking up the IR and transmitting through the speakers. That would explain the difference in "chirping" between buttons. The IR is sending out a different frequency thus making your chirping sound different.

    Thanks for the replys, guys. I'm going to do more troubleshooting when I get a chance.
    Mike,
    How did you get rid of your ground loop problem? Or did you? Thanks again.

    Tim
