CPWizard not controlling volume in Windows 7

[TheManuel]

I am transitioning my cab from WinXP to Win7, keeping a dual boot setup for the moment.  There are many things that were working fine in XP an are not working in Win7, which is the reason I resisted changing for so long.

One example is CPWizard not contolling the computer's volume, as it does in my XP setup.

Can any CPWizard users out there with Win7 tell me if volume control works for them?

Don't have an answer but would be curious as to what the driver was for upgrading?

Don't have an answer but would be curious as to what the driver was for upgrading?

A few years ago, I wanted Win7 because I could then run MAME64 which runs a few games I play faster.  However, this wasn't enough incentive since it's only a few games that my system has trouble with (all 3D) and I hardly ever play them.  I also wanted an OS that would enjoy support for a long time.  However, when I started transitioning, I ran into so many problems that I just decided to stay with XP and abandoned my dual bootable Win7 load.  The biggest problem was that I use component cables on a CRT TV and in Win 7 I could not find a way for the nVidia drivers to output a signal that was scaled from the 1024x768 I like to use to the 640x480i my TV needs.

With the release of MKKE, I really wanted to have the game integrated properly into the cab along with all the others and the game doesn't run in WinXP so I'm giving Win7 another shot.  I've gotten around the biggest hurdle, the issue with the video signal, by switching over to S-video.  This allows me to scale the image properly and I've found settings in the TV's service menu that help me get the colors close to what I was able to get with component cables.  The only noticeable difference is a little red color bleed from in certain situations but it's not too distracting and I can live with it.  It turned out my card's s-video output is quite decent.

That aside, I've kept running into issues at every step of the way and I keep finding solutions or work-around's.  It's a lot of trouble for just one game but I figured I might as well make the cab robust to future additions that might not support WinXP, require directx >9, etc.  Besides, it's a hobby so this gives me something to strive for.

I understand entirely.  My PC upgrades seem to occur based on the need to support a particular game.  Have you considered volume adjustment via Mame itself?  You can also set the volume by going into service mode for some games.

Well, I use the cab for many games besides MAME so controlling volume universally is more advantageous.  I know there are more than one app out there to control volume, so if I can't it to work with CPW, I'll use one of those but I would like to make it work since I always have CPW running anyway.

I've come to realize this is an issue with Win7 not allowing applications to control the main volume.  If I open up the volume mixer, I can see a slider for CPW and the volume control keys can control it but the main volume remains unchanged, so the feature does not work with Win7.

I'll have to take a look at that other tool, as I don't think headkaze is working on CPW anymore.
