The newest drivers
are now working. Here are the steps to make sure you get a clean install and setup:
1) Uninstall any previous versions of the drivers
2) Delete C:\Windows\SysWOW64\HsMgr.exe if it exists
3) (Optional, but prevents lockup issues for many people) Go to Control Panel => Sound and disable the "Digital Output" device.
Everything should now work. If anyone is still having problems after these steps, then please post a reply. I've left the original solution below, but I wouldn't recommend using it. Old Solution:
I had the exact same problem, but I was able to resolve it. It appears that the 32-bit sound manager from ht omega is causing this problem (HsMgr.exe). Anyways, here are the steps to fix the problem. These steps also include a fix for window volume control not controlling all speakers also:
0) If you have ever
had an ht omega driver
installed then uninstall it and delete the file C:\Windows\SysWOW64\HsMgr.exe.
1) Download the vista drivers for the sound card http://www.htomega.com/new/s81731ex.zip
(this is a newer version than currently listed on the website) and the Windows 7 drivers http://www.htomega.com/new/striker81737W7ex.zip
2) Extract each set of drivers to separate folders (I'll assume they've been extracted to s81731ex and striker81737W7ex respectively).
3) Copy striker81737W7ex\Program to s81731ex\Vista\Program
4) Copy striker81737W7ex\SoftwareDriver\dll to s81731ex\Vista\SoftwareDriver\dll
5) Delete s81731ex\Vista\SoftwareDriver\dll\HsMgr.exe
6) Right click on s81731ex\Vista\Setup.exe and go to properties. Then go to Compatibility and select "Windows Vista (Service Pack 2)". Press OK.
7) Right click on s81731ex\Vista\Setup.exe and pick Run as Administrator.
When setup completes, reboot and your issues should be solved. Let me know if this fixes it.
