Win7 SpeakerConfig Registry Key Batch File

[zian]

Howdy,

I want to use EG to change my speaker config when I switch monitors/sound device (via HDMI Sony Amp etc).

I found the Registry Key that changes the speaker config to 7.1... exported it.
Click it directly... it works/changes to 7.1.

I created a batch file to call up that registry key.
Click it directly... it works/changes to 7.1.

I try to call up that batch file in EG via Start Program/Application and it runs the batch file but does NOT change the speaker config.

Is there something I need to add/change to the EG Start Program parameters? Maybe command line something or other.

Thanks for any help.

First come to mind:
Try to use full paths inside bat file. Also, call your bat file with full path.

Thanks for that wakko.
But no go yet.

Full paths.... like this...
my batch file...

Code: Select all

REGEDIT /S  "C:\Users\SSD-666\Desktop\71.reg"

I have tried moving both the batch and reg key to root of C, to different places, renaming them.
Nothing like that would help it work via EG.

I'm suspecting your problem is that EG is running the 32bit version of Regedit, so the registry is update in the wrong section if you are running on a 64bit Windows.

Try this In EGs Start application, put in Executable:

Code: Select all

c:\Windows\sysnative\cmd.exe

That should run a 64bit CMD.exe. The sysnative is a virtual directory that points to the 64bit system32 when running a 32bit program.

Put in Command line options:

Code: Select all

/c start regedit.exe  /S  "C:\Users\SSD-666\Desktop\71.reg"

And that should run the 64bit Regedit.

Hope this helps.

What if you use EventGhost's built in registry changer, rather than a batch file? Do you still need to use sysnative trick?

By default a 32bit program can't access the 64bit part of the registry.

There is a parameter KEY_WOW64_64KEY that needs to be used to access the 64bit registry. I don't know if EventGhost uses that.
