Apparently I'm missing something ...

Create a Lib folder and put VA.ahk into it.

<!-- m -->http://www.autohotke...nctions.htm#lib<!-- m -->

[stevenospam]

I created the Lib directory and moved VA.ahk into it. The error message is the same.
I am running Vista. AHK is installed in c:\program files\AutoHotkey. There are two subdirectories compile and Lib. topology.ahk is in \program files\autohotkey\. Autohotkey runs as a normal program e.g. not in XP compatibility mode. The topology script still fails at the
COM_CoInitialize() instruction.

[stevenospam]

I got this working. In case someone else has the same problem:
I reinstalled AutoHotkey_L but selected ANSI instead of UNICODE. I also installed the ANSI version of COM.AHK into the Lib directory. Now it works!

[Lexikos]

FYI, the topology script is extremely outdated. It does not support the Unicode build. VA.ahk itself (v2.1) supports the Unicode build and does not require COM.ahk.

[stevenospam]

Ah ha. I'll reinstall to support Unicode then.

I am trying to change a mixer volume level in Windows 7 x64 and got stuck. I don't want to change the master volume, but the volume of a second sound card. I need help.

I am using Vista Audio Control Functions v2.1. If I run the following script:

While (dev := VA_GetDevice("playback:" A_Index)) 
{ 
    devlist .= A_Index ": " VA_GetDeviceName(dev) "`n"
} 
 
MsgBox %devlist%

I get the following result:

<!-- m -->http://img192.images...0/topologyq.jpg<!-- m -->

Now if i use the following script to get the master volume:

dev := VA_GetDevice("playback:7")
devname := VA_GetDeviceName(dev)
volume := VA_GetVolume("","",dev)
MsgBox %volume%

I get the master volume level. But if I try to get the volume level of any other playback device, no value is returned.

From reading the VA documentation, I understand that this probably has something to do with subunit's, but I cannot figure out how to go about finding those values.

Can anyone help? Thanks.

[Lexikos]

Please note that VA_GetVolume("") does not retrieve the master volume: it retrieves the volume of the first subunit. In some cases the effect is the same, but not all. My system has two "devices" for the digital outputs - these have no volume subunits whatsoever, so only VA_GetMasterVolume(device) will work for them.

Which device are you trying to control and how would you change the volume by hand? On the Levels tab of the audio device's Properties, the box at the top controls master volume and any boxes below it control subunits. In my experience, the controls shown on the Levels tab have been in the same order and had the same names as the volume subunits, but this might not always be the case.

Note that "volume of a second sound card" amounts to "the master volume of device 2". For instance, VA_GetMasterVolume("", 2).

If you need the subunit names, use the revised topology script which I just uploaded. You could use a numeric index instead, but then you'd either need to know the order they're in or experiment to figure out which is which.

[kalia]

Thank you very much for the response Lexikos.

My system has two "devices" for the digital outputs - these have no volume subunits whatsoever, so only VA_GetMasterVolume(device) will work for them.

VA_GetMasterVolume worked. I have 2 Audigy Z sound cards (plus the onboard sound). I am using kx drivers with the Audigy cards to separate each output as a stereo channel. I was able to control the separate channels (Wave 2/3, Wave 4/5,Wave 6/7,) through the windows mixer, but no other volume control programs would recognize these channels in Windows 7 (x64).

Also, thank you for uploading the revised topology script.

I wasted a lot of time with VA_GetVolume("") and subunits. I should have asked for help earlier. Now I can spend some time to compile an .exe with parameters to control the volume of the separate channels (from what I have read, it should be possible - I hope).

Thank you again.

Hi I'm just starting with AHK but I like it a lot already! I tried to patch your script to my needs and partially it's working.
my goals are, beside the "basic" master volume control, a control of the subwoofer. i wanted to decrease the volume in 4 steps and then let it go back to 100%. it's not possible to mute the subwoofer (realtek soundchip), but 0% is fine, too. i got it working, but the gui is just grey with an empty windows under it, when i use the subwoofer, but no error message atm
so thats the code, hope its not to messy...

the other thing: i would like to have the muted image of the subwoofer, but as i said, it cant be muted so the only way is to use a d-tour. i tried something with

Volume_Bar_Update2:
if VA_GetVolume(0, "Subwoofer")
	{
	GuiControl,28: Show, MuteOn
	GuiCOntrol,28: Hide, MuteOff
	}

but it didn't work. well, maybe its fixed when the "normal" subwoofer gui is fixed, but maybe you'll know the answer...

thanks a lot in advance and thanks for the great script!

[Pio]

Noone? I know, it's a lot to read, but most of it is just the original file...

[Lexikos]

Did you have a specific problem you needed help with? If it's not specifically a function of VA, you should post in Ask for Help.

[Pio]

Well, I thought its best to post here as this is directly related to va. I must say I'm not a prgrammer, so I just tried to adopt things from the Volume Control.ahk
My biggest problem is that the gui isn't working for the subwoofer. I tried to create a second gui similar to yours, just with another grphics (subwoofer icon instead the normal one, I can upload them if needed), named as shown in the code. the master volume is working, but the gui for the subwoofer doesn't show correctly. I tried a few things, but unfortunately I can't see the problem:

When this is solved (this is secondary and I can try on my own at first), I try to make the gui look like the subwoofer is muted when it's at 0% (as said, there is no such function to mute the sub).
Thanks, Pio

[Lexikos]

Let me rephrase: If you are having a problem calling a VA_..() function, post here and say specifically what the problem is. Otherwise, your problem is not directly related to VA, so if I don't have an abundance of free time I'll just ignore your post. If you post in Ask for Help, it's likely that one or more of the many other users of this forum will help you.

As it happens, there are two basic errors in your script that have nothing to do with VA. The first I noticed is this:

Gui, 29: Add, Picture, v[color=red]BF%A_Index%[/color] w5 h29 x%startp% y15 gVolume_Bar_Click, %A_ScriptDir%\Pictures\Full.png
   Gui, 29: Add, Picture, v[color=red]BE%A_Index%[/color] w5 h29 x%startp% y15 gVolume_Bar_Click, %A_ScriptDir%\Pictures\Empty.png

These variables have already been used by the other GUI. You must use different variable names. This got me thinking "why isn't it throwing a great big warning sign in the author's face?" The answer is your second error:

...
return ; Nothing after this line will execute.


Gui, 29: +AlwaysOnTop +ToolWindow -caption +LastFound
...

See The Top of the Script (the Auto-execute Section).

If you need further help, please post in Ask for Help.
