So I got a Mirosound PCM20, and I've been setting it up in DOS. Quite strange card, it seems to work for MIDI and SB Pro although it seems to forget its settings and needs to be initialised repeatedly. Full of character. Sometimes plays nice and sometimes plays awful. Sound effects in Jull of the Jungle are nasty, but music in XWing is nice.

My problem however is that I have an IDE CDROM attached to the CD interface and DOS doesn't recognise it. I'm using a file called CDSETUP.SYS in config.sys with this line:

devicehigh=c:\pcm20\cdsetup.sys /T:I

which should enable the CD interface, but I get the message "Sound card not found". At first I thought the card was dead but in fact it plays MIDI music in X-Wing and I guess SB or Adlib in Jill.

The documentation says cdsetup.sys isn't a full driver, so I guess I need to find oakcdrom.sys or some such and add that to config.sys. But that wouldn't fix the sound card not found.

Wondered if anyone else had any experience with this card who could shed light on what might be the problem here with the CD interface.

I guess I need to double check the cable and CD drive but the cable was certainly working last week, and the CD drive itself is not dead.

Of course, that might mean the card is just sort-of dead, which seems all the more likely since it "forget its settings and needs to be initialised repeatedly".

I guess you could take a closer look at the card and make sure there aren't any dirty contacts or obvious physical defects.

Yes, it could well be on the way out in some way.

I've already cleaned it with isopropyl alcohol, so it shouldn't be contacts.

Some of its apparent randomness may have been because of where it was storing its settings, which I hadn't fully grasped at first. That doesn't explain why it seemed to need to be reinitialised after exiting a game though but I'm hoping a pattern will eventually become clear on this.

I have one of those around here. Never tested it much, but i can do some parallel testing with you.

What drivers are you using?

Thanks for the offer. Some peogress though:

I downloaded drivers from mirosupport.de. But I saw a screenshot of the sndindos.exe program and that had a tick box for external ide - I'm pretty sure mine didn't, in which case maybe I can either find a different version or see if the file where it stores it's settongs can be edited directly. I'm assuming it may use soundcfg.ini for dos even though it's supposed to be the windows settings.
