Sound problem in dosemu 1.1.4

Sound problem in dosemu 1.1.4

[Thomas Pallmann]

Hello,


I have a small problem with sound in Dosemu. 

The sound config seems to be ok since the setup program of my favorite game 
(the reason i run Dosemu) recognize the soundcard, although it recognize a 
soundblaster 16/awe card. If i disable sound in the dosemurc, then the 
setup is unable to find a soundcard. 

Now with sound enabled in dosemurc and using SB pro or plain SB in the 
sound setup program of the game, all i get is a static/crackle noise out of 
my speakers. Sound worked fine in Dosemu  1.1.3 with the same program and 
setup which confuses me a bit.

So my Question is, since i'm rather new to Dosemu, where i could start my 
troubleshooting? I'm using the sourceforge vortex driver for my Terratec 
Xlerate (aureal chipset). If you need more infos i will be glad to provide 
them.

Please fix your buggy aureal drivers.
The attached patch will help you to
start doing that.
Third-party drivers are not supported
by dosemu anymore (except the PCSP driver
of course:)
