Yamaha XG YMF754-V 4 channel problem

My problem starts with the Yamaha YMF724F-V. I've had the YMF724F-V for at least 10 years and have had no problems with it. I recently had the opportunity to upgrade to the YMF754-V (second-hand not brand new) and even organised myself a decent 4.1 speaker set. My problem comes in that I originally used the YMF754-V with the drivers for the YMF724F-V as a 2.1 system instead of a 4.1 seeing as I didn't have internet access to download the correct drivers for the YMF754-V and no matter what I tried I couldn't get my rear speakers to work. Eventually I got the correct drivers for the YMF754-V directly from Yamaha's site. I installed the drivers but my sound didn't want to work. I checked my sound controls in control panel but everything was disabled, after seeing this I went into device manager but my whole device manager was blank. I've tried uninstalling the old YMF724F-V drivers and installing the YMF754-V drivers but same problem. I've tried deleting the drivers for the YMF724F-V and then installing the other drivers but same problem. I even tried deleting everything Yamaha out of my registry but still the same problem occurs. Everytime this happens I'm forced to use a system restore. Anyone got any ideas?

Does booting into Safe Mode help any?

Can you get it working with the 724 again?

Safe Mode doesn't make a difference unfortunately no and yes the 724 works fine still. The drivers support both the 724 and the 754 but its the only driver package I could find on the net on Yamaha's official site and on unofficial sites. I'm assuming that, that specific driver package supports 4.1 as well as normal stereo for the 724 because I couldn't find any driver packages only for the 754 / 4.1 support.

Starting to sound like flaky hardware (the 754). Unless there is a setting hiding in the soundcard properties or Windows sound properties that needs to be changed

Any way you can connect/borrow an old hard drive to swap with the current one, to do a clean OS install with the 754 drivers for testing.
Make sure the computer is disconnected from the net, you do not want it Activating itself.

Do you have a link for the specs, so I can see whay I am dealing with?
I can't find either of them on Yamahas site, but one of the few English things I found seem to say this is a PCI card, instead of an external device I was thinking it was.   : /

As far as I know the 754 is supposed to work fine. Its barely been used since it was brand new. I checked for windows settings and the soundcard settings in windows but there is nothing there that helps unfortunately. Even if I do set the speaker system to quadrophonic or on surround sound speakers it still only uses 2.1.

I cannot unfortunately get my hands on a clean hdd for a new OS install with the 754 drivers but I am looking into alternative OS solutions atm, looking into linux but I don't have anything yet so for now I'm stuck with xp pro.

My home pc isn't connected to the internet foruntately so that wouldn't pose a problem.

Yes it is indeed a PCI card, my apologies for not making that more clear.

http://en.wikipedia.org/wiki/Yamaha_YMF7xx:
"The final and most advanced version of the YMF7x4 chipset series is the YMF754, which also features standard four-channel output, but adds lower power consumption features. The most feature-rich soundcards based on the YMF754 are the Labway XWave 6000 (which has an additional hardware chip to emulate 5.1 surround sound and a six-channel amplifier providing 2W per channel)"

The board for my particular 754 model is indeed the XWave 6000, just so that you know.

This is a pic of the model I have:

http://wiki.eazel.com/it/images/5/55/Driver-yamaha-ymf754.jpg

Thats about all I could find unfortunately. As I have said before I run XP Pro I'm not sure about my mobo and cpu but I'll give you those specs later.

Thanks for the info.
I will do some poking around, but so far I don't see any reason why it isn't working.
I have a long-shot thought that the motherboard may be using an older PCI Compliance level than the card needs to fully work, but that is really a stretch.

>> which has an additional hardware chip to emulate 5.1 surround sound and a six-channel amplifier providing 2W per channel

Maybe the speakers need more power than the card can give?

I guess this is the driver you are using?

http://www.sound-drivers.org/?curpage=5&squery=Labway

60. Labway - Xwave 6000 [Pro] (ymf754) ...
Labway, model: Xwave 6000 [Pro] (ymf754), WI524514.exe,
Windows XP (Note: might work with other versions of this os.)

67. Labway - Xwave 6000 [Pro] (ymf744) ... (different model #, but looks like the same file)
Labway, model: Xwave 6000 [Pro] (ymf744), WI524514.exe,
Windows XP (Note: might work with other versions of this os.)

Maybe the W2K driver will work:

73. Labway - Xwave 6000 [Pro] (ymf744) ...
Labway, model: Xwave 6000 [Pro] (ymf744), DWI2240L.EXE,
All Windows 2000 (Note: might work with other versions of this os.

I'm actually not using those drivers. Downloaded them now and going to try them one for one tonight, will let you know how that turns out.

I'm currently using the official drivers for the 754 I got here:

Those drivers have absolutely nothing to do with yamaha apparently. The first two are self extracting exe's for a program called mp3cut and the last one is a driver package for a Realtek card which doesn't even want to install, the drivers that is. The speakers are 4.1 speakers that worked before I had the card with the same card and they have their own power source and amp so the speakers aren't the problem. The problem is that only my front channel works but not my rear channel whether all of the speakers are plugged in at the same time or not. My mobo is the Asus P4S8X-X running a 2.8ghz P4.

Sorry about that.   : /

I'm stumped.  I see no reason why they aren't working.
It still might be a 'not-quite-right' driver, but with the Device Manager problem I am leaning toward the card being buggered.

As I've said, I doubt its the card. Its been known to work in the past and its barely been used since it was bought. It might be my windows installation thats buggered but I don't have a copy I can use to reinstall it. I don't know what happened to the drivers cd otherwise I'd have used that and the official release drivers are the only drivers I could find for the card. What bothers me is that its a driver package that includes drivers for 2.1 cards while a card for 4.1 and 5.1 is supposed to be supported by this driver package as well. I dunno :( Also if it was the card the sound wouldn't work at all, its highly unlikely that only the rear channel would be busted.

Nothing new on drivers from my end also. I looked to see about a registry edit, but nothing on that yet, either.

I'll try the card in a different pc with the same drivers I used this weekend to see if it makes a difference. Its just lots of trouble moving my speaker set around lol.

Ok. *sigh* I tried it and it doesn't want to work on the other pc either. I have made sure that both channels work so it isn't the amp I'm using. What I have figured out though is that the rear channel on the sound card doesn't work after all, it has power (which is why I previously thought there is nothing wrong with the sound card) but it seems there is no signal coming through. I tried speaker testers to see if I can get anything to work but unfortunately it didn't. My biggest problem is that I still can't say whether it is the sound card or the drivers that is causing the problem. I got a little bit of cash recently so I think I'm just going to invest in a cheap 5.1 sound card. I'll let you know how it works out once I get a new one. One last question off topic though, how many points do I need for guru status?

My apologies for not having responded in a while. It was a mixture of being busy and forgetting :P

Seeing as I unfortunately was not able to fix my little problem I'll just accept your answer to my question about the guru certification. This way at least all your hard work wasn't all for moot.

I'll post when I am able to afford a new soundcard and if it works in case you're still interested then.

Thank you for your trouble coral47, it is much appreciated.
