#164 FreeDOS 1.2 RC1 -- JEMM386.EXE Sound Blaser incompatibility

[Szőgyényi Gábor]

There is a Ensoniq ES1371 / Creative Labs CT2518 [AudioPCI-97] PCI sound card in my PC. The problem is: no sound under FreeDOS 1.2 RC1.

With boot menu: Load FreeDOS with JEMMEX, no EMS (most UMBs), max RAM free
No error message, but no sound.

With boot menu: Load FreeDOS with EMM386 (Expanded Memory) and SHARE loaded
No sound, but error message shown. Picture attached.

Both times I used the "SB" option while starting JEMM386.EXE
The sound card works under linux.

I assume these drivers were tested successfully in MS-DOS. Mimicking that successful config would be the best solution. However, it could be a rare bug (or undocumented quirk). In any case JEMM386/JEMMEX is no longer supported and not guaranteed to work or fix anything, even with "SB". Soundcard support is a weak link in DOS. My advice would be to do without JEMM unless you're sure you need it. If you direly need EMM386 and this won't work, sorry, you're out of luck.
