Working on an 820-3332 board with no audio; headphones do work, but when headphones are NOT plugged into the board, the audio icon is greyed out and I get the prohibitory sign when attempting to adjust volume. I've had this issue (or a similar one) before, and removing R6895 resolved (or bypassed) the issue.
I removed R6895 on this board, and it did not resolve the issue, but instead made it more odd; now, I get no audio (still), however when I plug the headphones in, I DO get audio through the speakers but NOT the headphones. No audio whatsoever through the headphones when they are plugged in. As soon as I unplug the headphones, then I get no audio through the speakers again. So, I've replaced R6895 and I'm back to square one.
All surrounding resistors are measuring fine, and there's no sign of liquid. Does this sound like a bad U6201? Headphone jack is part of a known-good test case, so I don't think that's the issue. All help appreciated.
