Any Way to Change the SoundBalance from Script

SoundSetWaveVolume attempts to retain the existing balance beween left and right channels when you raise or lower the volume. However, SoundSet does not.

To answer the question, I don't think so, unless ControlTypes PAN or QSOUNDPAN exist on your device and do something useful.

I think setting the balance involves changing the relative settings of the left/right/front/rear channels. I'll look into it.

Anything new on this problem?

>PAN or QSOUNDPAN
doesn't help (not supported) and
>SoundSetWaveVolume
doesn't help eighter(no change in balance-settings).

Any other simple solution would be welcome as well. Like registry editing or something. (But please no active-x, java or VisualBasic)

Thanks.

No progress yet, though I suspect it would only take a couple hours to research, develop, test, and document. Anyone with the Windows API and C++ programming experience is welcome to look into it.

At the moment, I'm working on items that most would agree are higher priority: complex expressions and passing parameters to functions/subroutines.

In any case, I'll raise the priority of the sound-balance to-do item. Thanks for mentioning it.

I'm interested in this PAN setting too. Any luck yet? btw, check out my mixer at http://www.autohotkey.net/~bLisTeRinG/.

I don't mind hacking the registry if neccesary either. As you can see from my mixer (above) pan would be great! Hint hint...

Ok, I'll go away now... Wink

No luck yet. There always seems to be something that's higher priority.

I think it can be done with DllCall; it's just a question of doing the research or finding an expert.

Still no way to adjust the sound balance with SoundSet?

About all I can figure out is to select the balance slider in the Volume Control window and have AHK send right and left key presses (very messy solution). Ex:

ControlSend, msctls_trackbar321, {left}, Volume Control

In light of the fact that Vista has a completely new mixer interface, there's a good chance I won't devote time to enhancing the old interface. Therefore, it's probably best that you or someone else delve into the API to find out how to do balance control. There's a good chance that only a few DllCalls would be necessary to achieve it. The problem is finding them and determining what parameters to pass.
