General Sound doesn't work with players

Greetings, All! A few months ago I pulled my GS out of the computer and put it in box to make room for new devices. Enough Having played/suffered enough with the new ones, I put the GS back and was I'm unpleasantly surprised - not a single player works. GS itself they find it, but they can’t start playing the music - they just “hang”, i.e. spinning in an endless loop. In games adapted for GS, music and effects are present. As far as I understand, the players simply stopped receiving from GS some information (the number of the position being played or volume/frequency) and therefore hang. Please advise which microcircuit to replace. I have the diagrams there is no installation of elements either. Just point your finger at which one microcircuit and in which row to change. Or maybe there will be a craftsman in St. Petersburg who will take on the repairs? GS latest version, which without jumper for expansion memory. Help. [REAL ZX]
