With the maestro 32/96, I had success. The drive was recognized, but then I got a command.com failure message before the boot completed.
It must have been able to read from the IO controller with CF first, as MSDOS started and loaded the CD driver. Then it looked a bit as if control had passed to the soundcard ide-IO and now it no longer found the HDD.
That's strange. This indeed sounds like a conflict, but I don't think it's an I/O address conflict. I don't know of any sound card that can be set to the primary IDE I/O adress, so port 1F0-1F7 will not be disturbed by the sound card. The next possible issue might be an IRQ conflict, but as I expected, the Maestro 32/96 does not even have a contact on the ISA pin for IRQ14, which is the IRQ used for the primary IDE port. Given these facts, I consider a conflict between the sound card and the primary IDE port unlikely.
Please check what settings (I/O and IRQ) the sound card is configured to, and post a list of further cards in your system. Also, if you get an error message trying to load command.com, please post that message. Furthermore, there are multiple well-known IDE CDROM drivers, you might want to try a different one.
