No sound in many games in groovymame? (HD4350 related? CRT_Emu?)

And it only happens with switchres on. Works without. What should I do!?

Yes that's what I mean by running full screen.

You may try updating the video drivers with a more recent version, to discard the CRT_Emudriver.

You mean switching to soft 15khz?

Yes. But before it would be interesting to see if the problem happens with a normal monitor, 31 KHz, full screen.

Ok, I'll try that! Thanks for you patience and all your help. You should get money for that.

Tried to install the latest catalyst... now my sound isn't working at all. Maybe the onboard sound is just utter ---steaming pile of meadow muffin---. I'll get a soundcard and try again.

did that several times, even bought a new soundcard today and disabled the onboard sound. doesn't work.

Okay one last thing I want to try... I will make my own VGA-Scart cable... let's be SURE that the umsa isn't the problem.

Did you ever look at the control panel sound properties "audio" tab?

Was everything set to use your on-board sound?

The fact that you installed a new sound card and it still doesn't work, leads me to believe that something is wrong in windows, either in the control panel setting for your audio, or possibly some sort of mixer settings.

When you test, you should be plugging headphones directly into the green line-out port each time to rule out any other possible interference.

Are you positive that your CPU or motherboard isn't being overclocked, even unintentionally?  Sometimes, when a motherboard is overclocked, it raises the speed of the PCI bus, which will cause problems with onboard devices and/or add-in cards.

I would try going into your motherboard BIOS and resetting everything to default just to be sure.
Also, are you using the latest BIOS for your motherboard?  Maybe there's a know problem with the version you're using.

Of couse... that's the first thing I did and I wouldn't have ANY sound at all.

I found something interesting though... while the computer vga was connected to the pc monitor but the sound to the umsa (sound from the cab) the sound in windows was stuttering. interesting. I'll see what happens If I connect an external sound source.

Okay I just found the problem. It's the UMSA. I connected my heaphones to the soundcard and got normal sound.

I thought you tried that earlier.

How are you supplying power to the UMSA?

[Endprodukt]

It came with a 5v power supply. And yes, I've tested it but the other way around. I hooked it up in different ways. But my testing failed because I've tested all in 60hz mode. It works on that.

 I mean... sound works with severel resolutions but not with others? Seems like it's not getting enough power or something.

[krick]

Is there a support forum for the UMSA?  You can't be the only person having this problem unless it's just a random defective part (or defective power supply).

[Endprodukt]

I will get in touch with the people who made my UMSA.

Thanks for all the support... whish I would have tested with my headphones earlier... 

[Endprodukt]

So, THEY say, the UMSA can't be the problem because it's just sending the sound to the TV without touching it. So... the last piece in the chain would be the TV itself. Is this even possible?

[krick]

I guess it's possible.

Do you have access to an other SCART capable TV to test with?

It could also the cable between the UMSA and your TV.

Do you have access to another cable, possibly from a different manufacturer for testing purposes?

[Endprodukt]

Got a new cable today, tested with another TV set and it seems to be the TV causing the problem. That's why I couldn't identify the UMSA as the problem in the beginning. I guess I can't do much about that but have to get a new TV.

That's the most unexpected result ever. I'm glad to see that at least you could find the source of the problem.
