Symptoms

No sound from PAS-16 Plus sound adapter following Selective Install and alterations to CONFIG.SYS per Warp User's Guide Chapter 19.

Hardware

  • Media Vision Pro Audio Spectrum 16 Plus adapter
  • Media Vision Pro Audio 16 Basic adapter
  • (possibly other PAS-16 family adapters)

Problem

Bad MVPRODD.SYS driver in Warp GA.

Fix

Obtain a new driver from the Media Vision BBS (510-770-0527). The driver is in OS2.EXE, which is a self-extracting archive (194972 bytes).

For comparison purposes, here are the drivers:

MVPRODD.SYS (BBS)    9-21-93   3:09p     59480
MVPRODD.SYS (Warp)  10-08-94   4:02a     51246

Notes

The MVNOTES.DOC file from OS2.EXE also recommends making a change to the MMPM2.INI PARMSTRING value.

If you are experiencing white noise (hiss) prior to OS/2 Warp system sounds, try adding a /T:1 parameter to your MVPRODD.SYS entry in CONFIG.SYS.

Also, be aware that installing the OS/2 PAS-16 drives via Selective Install does not appear to update the Win-OS/2 drivers. To get PAS-16 sounds with Win-OS/2, You'll need to start up a Win-OS/2 session, open the Control Panel (in Main), and do a Drivers / Add for the "Unlisted" drivers in \OS2\DRIVERS\MVPRODD.

Media Vision is now shipping PAS-16 adapters with a new, improved chipset (MV-508-B) which replaces the older MV-508-A chipset. The drivers shipped with Warp do not support the new chipset. It is not yet clear whether the OS/2 driver from the Media Vision BBS supports this chipset properly.
