any owners of this TV having audio problems with it? i have 2 issues; 1. variable audio in/out does not seem to work when connecting tv to my sony receiver. however, when i connect the receiver to the TVs monitor out it works. the monitor out is for connecting the tv to another tv basically not a stereo receiver. 2. every so often the audio (TV speakers as well as stereo speakers) experience interference. it sounds like static but it doesnt affect the video just audio. i cant seem to pinpoint it.
