First post, by Eep386
I've decided to start a running log, that catalogs which Creative Labs-built ISA sound cards suffer floating op-amps, and where to look on the cards in particular. Do note that the locations of the parts in question tend to vary between different revisions of the same CTxxxx model number, so don't be surprised to find that your card doesn't match the description of a log posted here. I'll occasionally add more to this post (and make further posts as needed), as I discover Creative-made ISA cards with this problem.
Sound Blaster Pro 2
Pins 8-10 and 12-14 of the quad amp at U11 are floating. No other floating amps detected on this particular board.
Sound Blaster 16
U5 and U7 have floating, unterminated amps at pins 12-14 each. This fault is common to both CQM and YMF289-fitted versions.
Sound Blaster AWE32
CT2760 (first revision, TDA1543T DAC)
The entire left half of U22, the right half of U27 and the bottom half of U30 are floating.
Life isn't long enough to re-enable every hidden option in every BIOS on every board... 🙁
