I've got a strange problem and I don't know if it's just a defective box, because my audio issues are only when watching my cable box. Basically, there's a sound problem because I could be watching something and then it goes to commercial and then the volume drops on one commercial and goes louder on another. Was watching the 49er Football game and the announcers were fine, but sound in the background ( The referee talking into the Mic ), you could hardly hear. Watched Bill Maher on HBO and he sound had to go up a lot higher than usual, switched it over to something else. Sound was fine, then the commercials came on, problems started all over again. Went into the audio settings for the box, but what's strange is when I switch it from AUTO to PCM, the opposite happens. The announcers talking in the football game, you could hardly hear them. Commercials turned to their normal sound, but any dialog audio was less loud than usual. I've tried every audio fix that I can think of and nothing. Put back in the logitech Revue which was the replacement for the Sony and all my volume problems go away. Even recorded the football game to test the audio when I put the logitech revue back in where the Sony was and the audio coming out of the commercials is fine, whereas with the Sony, the volume on commercials was half the regular volume. This all sounds like a good thing, because you're thinking low sound on the commercials....great, but that sound also applies to shows where there's voice dialog going on in the background like back at the Football studio, which I can hardly hear and have to crank the volume. I know it's an issue between the cable box and the Sony Google Tv hardware, because I'm using Google TV for movies through the USB port, watching the slingplayer, watching web video and running google music and I don't encounter any audio issues when I'm running those things on the Sony. It's only a problem through the cable box and I've gone into those settings and changed whatever I could change in there, but that didn't make any difference, so if noone has any bright ideas, this box is going back for a replacement, and if that one is the same, then I guess I won't be holding on to this Sony as the audio going down for one commercial and then fully up for another is getting really annoying. Shame, because it did everything else really well. I'm thinking I've got a defective unit. I was just wondering if anyone has encountered this audio issue before.
