I remember it working for my old Yamaha card that was builtin to an old motherboard... Other than that, I don't know. -- |

Well, Descent 2 was perfectly capable of using the Windows Sound System driver on my laptop. Allegro wasn't. So there we go. -- |

I seem to remember not much actual work being done on it after it was added to allegro. -- |

I think perhaps you have become confused by the terminology? The Windows Sound System is a particular type of sound card. DOS Allegro does not (and probably cannot) hook into the windows sound drivers, offering support for any card. The WSS cards are of a similar vintage to the Disney Sound Source - you're unlikely to see one in the wild nowadays. But the hardware is documented on http://www.geocities.com/SiliconValley/Heights/6494/wss.html if anyone is interested. [My site] [Tetrominoes] |

Then why was Descent 2 able to use its Windows Sound System driver? The card was an ESS of some kind, and Allegro could use the ESS driver without problems. I believe D2's WSS driver worked on every computer we had, provided D2 was running in a Windows DOS-box. -- |

From http://www.mobygames.com/attribute/sheet/attributeId,78/ : Quote: The Windows Sound System was a sound card put out by (guess who?) Microsoft as an optimal sound card for Windows 3.1 multimedia applications. It was not compatible with any other DOS-supported "standard" sound card, so additional code was needed by DOS games to support it. From http://mail-index.netbsd.org/port-i386/1995/06/30/0001.html : Quote: Found such card lying around without any documentation or disks, tried In fact, http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q254081&FR=1 : Quote: The issue occurs because the Windows Sound System sound card is not supported in Windows Millennium Edition. From the Allegro file, wss.c : static void wss_wait() { int i = 0xFFFF; /* Wait for INIT bit to clear */ while ((inportb(_sound_port + 4) & INIT) || (i-- > 0)) ; } Enough evidence for you?

Thomas, you could access WSS cards provided windows was running. At least I could.. Then my card only emulated WSS, It was not a WSS card its self. In fact it was a really nice Yamaha chip that had the best hardware midi I've ever heard. (no patchsets that I could change...) -- |

Microsoft are to blame here. They have mixed terminology. The thing launched and sold as the Windows Sound System is an open standard for sound cards based on some widely available chips. Later on, however, Microsoft seem to have come up with the Windows Sound System 2.0, which according to http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q110377& "ships with drivers for five of the most popular sound cards." - including the sound blaster and compatibles. The original definition is still the one in most wide use, is the one most things mean when they refer to WSS, and is the thing Allegro means it refers to WSS. [My site] [Tetrominoes] |
