Folks, could someone please identify the card on picture below? It's presumably some variant of SG NX (Pro?), but so far I couldn't find 100% working drivers for it. The SG tools sometimes identify the card as Sound Galaxy EX, although NX Pro drivers identify it as NX Pro. FM music doesn't play in SG test tool, but sound works. On the other hand, in Doom II, FM works, but sound does not.
The card has volume knob and some sort of 50pin female expansion connector. No FCC ID, though! I found pictures of similar cards, but they've been (falsely) described as NX Pro (which should have SCSI interface, correct?).
Chips are AZT-NXPMIX0592 and AZTSSPT0592-U01. The small one marked "A" is an Intel microcontroller. The expansion port looks like it's mostly ISA signals. It has true Yamaha 262 OPL.
Thanks!
