Hello.
I've recently bought a Sound Blaster Pro 1 (CT1330) and I tested it on my retro computer.
Unfortunately, I noticed there are notable sound problems on Prince of Persia I & II. Voices and other digital sounds work fine, but not the MIDI music. So I concluded the sound card is broken as I've tested two Sound Blaster Pro 2 previously, CT1600 and CT1690, and they worked perfectly on the same computer and games.
To give a final conclusion, I've tested other games (Flashback, The Lion King, Nesticle and Massage emulators) and guess what? The sound works normally, even with my Sound Blaster Pro 1 (CT1330)! Then, I checked the settings on setup.exe for Prince of Persia II (the original Prince of Persia doesn't have a such tool) and I couldn't find any misconfiguration. Sound card is set at port 220 IRQ 7 DMA 1 for Prince of Persia II (the correct settings). I disabled the LPT port to avoid any hardware conflict.
So, why my Sound Blaster Pro 1 produces bad sound on Prince of Persia 1/2 and correct sound on other games, whereas I don't encountered that issue on my two Sound Blaster Pro 2 (all games work perfectly) ?
Thank you in advance for your answers.
