Changing sound volume

[simon kagwe]

Hi,

I am playing sounds using the winsound module. Is there a way I can change the
volume?

Hi,

volume?

The docs don't mention anything about controlling the volume, so I
doubt it's possible with winsound. However, I found this in the
archives:

It's some kind of wrapper for Snack that allows you to mess with the
volume. This site talks about Snack, winsound and another module:

And finally a way that might work using ctypes:

Hi,

Thanks for your reply.

I had already read about the Snack, but I can't use it since my program uses
wxPython for the GUI and Snack requires tk. The best option was the ctypes
method you told me about. I used the code in the sample, but I am getting the
following error:

exceptions.WindowsError Error 11 while setting volume

The author of the code claims it works. What could be causing the above error?

[ I am using Python 2.4.4 and ctypes 1.0.1 ]

Regards,
Simon

Maybe with pyGame, but you may have to switch from winsound to
pygame.mixer.music

I'm not sure what the deal is. I just tested that script on my
workstation and it works fine for me. I think I have the latest
ctypes, but I can't figure out how to get the version number off of it
to be sure. I am running Python 2.4.3 on Windows XP SP2 though.

You might try that pygames idea. I've never tried it, but you'd think
that would work.

That module looks suspiciously like one I have laying around on my
computer. That's okay since I had posted it somewhere. Try setting
SPEAKER_LINE_FADER_ID to 0. Apparently my assumption that it is always 0
was wrong. If that works I have a more flexible version of the module
which actually searches for the speak line fader id. It also has a
GetSpeakerVolume function.
