Hi,
I am looking for some expert opinion regarding the board in the pictures. The board comes from the right speaker of a stereo PC speaker set (Audyssey Lower East Side Media Speakers). There are two external audio inputs on the board: a 3.5 mm jack socket, and a S/PDIF optical. The two white connectors at the bottom and the right connect the board to the speaker box, which I am not able to disassemble any further. Both speakers have a tweeter and woofer. If input is connected using the 3.5 mm jack, then everything works fine. However if input is connected using the S/PDIF connector, only the woofers produce sound. Visually the only suspicious component I could find is capacitor 11 (using my labelling; marked as C27 on the board), which has some white residue around it. Any pointers how to get started fixing this?
