Heavy Gear 2 CD Audio help needed

Postby SpeedySPCFan » 2017-12-31 @ 16:34

Has anyone ever found a fix for this? Just reinstalled the game to go back to it, and I can't get the music working for the life of me on Windows 7. The IAS Control Panel refuses to play any CD audio in any of its tests, and even after patching every DLL and EXE I could find in the games directory with _INMM, CD audio still won't work. I'm about at my wits end here, any advice?

Specs:
Windows 7 Professional 64-bit
Intel i7 4770k
8GB RAM
GTX 1070

A user in this post indicated that he got it running by using Win95 Compatibility mode:

Also, a user at GOG.com had the following information on this topic:

'iasinst.exe' in the Setup folder on the HG2 CD needs to be run in Windows 98 compatibility mode to avoid EAR / audio errors (it might be a good idea to set everything on the CD to run in Windows 98 compatibility mode and as an Administrator before you install)

Good luck!

Didn't fix anything, sadly. Compatibility mode does absolutely nothing for me, so in a last ditch effort I just hunted down every version of the IAS installer, tried all of them, and got no music from any of them. I think however the audio driver works just doesn't play nice with modern operating systems.

The only solution I can think of would be to try and get the game running with OpenAL. Apparently the Linux version uses that for audio, which makes me wonder if there's a way to get it in the Windows version... probably not :depressed:

I have found the IAS files including the main 1.58 API installer applicable to HG2. http://www.vogonsdrivers.com/getfile.ph ... enustate=0

There was a thing in their FAQ about a CD-check issue, particularly with Hitachi DVD drives. They suggest the issue is to do with the drive and a firmware update may or may not fix this - the copy protect is on an area of CD > 650mb.

Thanks for uploading those, but I already tried all of the iaspkg installers and none of them make the CD audio work. I just emailed the address for the company Dan Bates (one of the creators of IAS) currently works at to see if they can get me in contact with him. I was going to ask him if he still has backups of either Version 1.75 or the earpds_nt.zip file. Probably not going to but hey, it's worth a shot.
