Have tried connecting the two pins with a bodge wire?

I'm not well-versed with the AWE64 Gold specifically, but I know the SB16 architecture quite well. On the SB16, both the A/D and the D/A conversion for standard digitized sound is performed in the CT1703 (or the older CT1701) chip. The TDA1387 is possibly for the AWE synthesized music only. The CT1745 is a digitally programmable analog mixer chip. The sound from the different sources (CD in, digitized sound, synthesized music) is passed through that chip before it is passed to the card's output. Unless the input of the right channel is shorted to ground, that chip should not be able to kill the analog right channel signal.

You might want to test whether the "right channel dead" issue affects all types of sound or it is limited to some of the sources. This helps you reduce whether the issue is before or after the CT1745A.

TDA1387 is only for EMU8000/FM output, SB side comes from the CT1703 as on SB16 and other AWE cards. The analog section is basically same as other SB16 cards too, using the same mixer chip and same general support circuitry.

But yeah, like mkarcher said, you should see if the right channel is missing on everything or only some select things.

Hi, I have stumbled here since I have similar issue, only that mine is the left channel.

I have acquired the card recently and did run diagnose software and it worked fine, however after few days no sound from the left channel. Is there a schematic for this card, so maybe I can try replacing the caps first things first ? I am good at soldering throughhole caps but not done any chip replacements honestly.

TIA
