Windows main audio volume per channel?

[Yincognito]

but the values are wayy toooo off.

Didn't test the code, but it's probably because the nested syntax for variables is not used after setting variables in the mouse actions, e.g. (see the end of the line below):

Code: Select all

LeftMouseDownAction=[!SetVariable dotL $MouseX$][!SetVariable outL (($MouseX$/100)*65535)][!UpdateMeterGroup vis][!Redraw]["#@#Addons\nircmd.exe" setvolume 0 [#outL] [#outR]]

Bottom line, if one sets a variable and wants to use the new value of that variable on the same line of bangs, then he must use the nested syntax, otherwise the old value of that variable will be used instead. Obviously, if the variable is not used on the same line of bangs, normal methods like updating measures / meters and classic syntax are just fine.

Waiting for the below part to be verified:

Got this limit of Rainmeter brackets while testing a workaround: Formula: Internal error I think, it can't handle more than 256 characters.

I doubt that such a limit exists. I would suspect some wrong or illegal syntax or logic in the formula instead...

Yeah, i reworked the code right after i posted the previous one and separated in different measures the commands. But still, sometimes NirCMD doesn't registering the command. Yet, basically works, so there can be a solution for this issue.
And thanks everyone for the nice helps!

Glad it works. But, you helped yourself Mr. McClane! I was just - around - yeah - while you were trying to work out a solution.

However, I think something like <Current>+<FixedValue> would solve any issue of glitches. But, I don't know how to retrieve the L/R Balance values in first place. Do

That can indeed happen - it's been a long time since using it for that purpose, but I believe I've encountered this behavior as well. In any case, you're not limited to NirCmd for this, so maybe other alternatives don't have this slight disadvantage.

I tested SetVol & it works (Not through Rainmeter). Try it once.

I believe you, but I'm not the one who has to decide on this - it's up to the OP.
Yet another alternative would be to try the dedicated NirSoft utility for this, the SoundVolumeView command line tool - it has /GetPercentChannel, /SetVolumeChannels and /ChangeVolumeChannel for per channel audio handling, and who knows, maybe it fares better than the main NirCmd executable in that regard (if the issue is from NirCmd and not the skin code, that is).

P.S. Another particularity of using command line tools instead of built-in solutions is that some reasonable delay between executions is unavoidable for an acceptable outcome.

Well i know that there is a lot of external scripts and small apps are out there for these kinds of needs, but my first thoughts are always originated in Rainmeter. Like "can i achieve a thing like that?" or "are there any plugins or ways to do that in here?"
But i appreciate your suggestion, i believe that would work in those circumstances.

I probably give that a shot in the feature, looks similar, we will see.

The delay between executions is expected and not a problem for me.

Thanks again for everyone!
I will coment on this if i reach any new progress.

Alright, let us know of the result. Personally I've not yet tested this in your scenario, though I might just do that today.

I have a teeny-tiny-suggestion: unrelated to the main topic, but it works Rainmeter-wise:

Set the Volume up to 100 (Mixed-Volume?) per device.
Set the max fixed ratio in which you want them to increase/decrease. Example: Left 100, Right 80.
Now, the simple volume-meters in Rainmeter and normal-volume sliders of windows would use that ratio to increase/decrease (As long as both are greater than 0). Example (cont.) At 100% : L100,R80 ; At 50% : L50,R45.

I get this is not what you want to achieve, but I wasn't able to wait till Yincognito's answer.

As promised, here's the (working) outcome:

I let most of the code unchanged, except some needed nested syntax for the variables in the mouse action bangs, as already mentioned earlier (I also changed to left mouse up and middle mouse up, it was more comfortable for me during testing). That alone made the code work as it should have (didn't test the original code at all, just went with the proper implementation). In addition to that, I added two RunCommand measures to get the left and right channel volumes, so the skin starts from current values communicated by the system in that regard. Therefore, you'll need:
- NirSoft's Sound Volume Command Line tool, placed in the @Resources\Addons folder of the skin (to get channel volumes)
- NirSoft's NirCmd tool, placed in the @Resources\Addons folder of the skin (to set channel volumes)
to have it all working (I used the 64bit versions, but it's up to you which architecture you prefer to use).

Feel free to adjust whatever thing you need from the code above (e.g. the "Speaker" device, in case you have it differently, something you can see in the SoundVolumeView utility from the same NirSoft).

P.S. In case it's unclear why two such tools have to be used, it's because the first tool couldn't set the left channel volume for me (only the right one), and the second tool doesn't seem to have parameters to get the channel volumes (or any volume, for that matter) at all.
