Loud Sporadic Clanking Sounds ...
I have been having a rather disturbing issue with my Integra 8.8 receiver. When watching TV via my cable box (connected with HDMI) I get periodic very loud clink/clank sounds from various speakers (5.1 setup). It is very sporadic and very loud .. so loud that I'm afraid it will blow out a speaker eventually. It only happens with cable TV, not on the other hdmi inputs (apple tv, oppo dvd, ps3 etc). This is the second cable box from a different manufacturer and the problem has occurred with both .. so I doubt it's a problem with the box. It happens sporadically and randomly .. and occurs with all settings (THX, stereo, direct, surround etc.).
It's really annoying when it happens .. any ideas on what is going on or how to fix it?
