sound card mixer controls

Highlighted
Has anyone written a dll to access the controls of the sound card mixer in windows?  I see that i can modify volume, but I actually need to have controls of both playback and recording levels.  Specifically the mic level of recording.  Just trying to save some time if someone has, dont want to reinvent the wheel.
Thanks,
Dave

Hi Dave
Don´t know if sombody has a dll to control mixer API.
I downloaded fron this site http://vrmixer.softvr.com/features.htm the activex to do that, Actually, I didn´t check it yet, but it seems to allow full control of windows mixer.
 
Hope it helps
Alipio

Thanks, ill take a look at this. 

In the meantime i found a vi  that someone here wrote that uses the winmm.dll from windows. It does not have any of the recording controls,(which is what i needed) but it gave me a start. With a few mods i can access all of the sliders in both playback in recording now.  Not perfect but it may work for me.  

 

Thanks!!!

Okay, i have made some modifications to another authors on this sites work and now have control of all sliders of the sound card mixer. Would some of you try this executable to see if it works on your machines as well(want to make sure it works with different sound cards ect......  I just opened the windows sound mixer and made sure the sliders were indeed changing.
 
It is pretty self explanitory i think, Just select master volume from pulldown to change master volume, then different sliders to modifiy the other lines.  If you want to modify record lines, then click the record box.  Please let me know if everything seems to work on your systems,,,
thanks,
Dave

I think most people (at least me) are apprehensive about running executables from foreign sources. Maybe you should post the VI instead (unless it's specifically the EXE you want to test).

i can post the vi as well if you like, I really wanted to have exe tested though b/c that is what will be used for my applications.

Pleas post the VI, I would like to see if it works on my machine but I will not do it if it is an EXE. Sorry

Okay, here is the zip with the vi's.  The Vi that I wanted to test is called MixerControl. It is a little messy but will be neater later 🙂 

It works pretty well on the two machines i tried here, but they have the same sound cards.  I also need to figure out how to read the value of the next mixer slider into my control so that it does not automatically change the volume of each newly selected slider. (you'll see what i mean)

thanks,

Dave

 

Also included are the original files that i used from another author on this site. (As you can see I did not change much) , they are all in the VolumeControl.lib.

Great, so far so good. Any idea on how to keep the volume from changing when each new slider is selected?

Thanks!!

Dave
