Hello. M-Audio have released an updated driver for the Revo 7.1, for Windows 2000 and XP, v.1.0.2.8. For some strange reason it comes without an installer. So I unzipped the files and copied them manually to the relevant system folders, then rebooted. But the Revo control panel still shows the previous driver version, 1.0.2.6. Trying to update the driver via the Device Manager didn't work either. Has anyone else been able to make sense of this update, please? Neither the M-Audio driver web page nor the readme file included with the update give any idea of what improvements the update is supposed to offer. Many thanks.

Try right clicking on the "revoboot.inf" file and selecting Install (be sure you have all the files that came with the .zip in the same directory).

What i did was..
Uninstalled the 1026,rebooted,extracted to hd-wherewere,add new device and browsed to that folder-it worked...

Thanks very much for taking the trouble to respond. Mr.Radar's suggestion unfortunately produces no results at all. Regarding zver's suggestion, I must admit I'm rather chary of uninstalling the previous driver, as I don't wish to lose all my settings. I might be more motivated to try it if I knew what enhancements the latest driver is supposed to bring. But thanks again for your help.

Open up the Device Manager, right-click your soundcard, and choose "Update Driver..." Go through the wizard and navigate to the directory where you extracted the files to.

(also, it's best to uninstall all previous drivers first before updating)

As I mentioned, I've already tried updating via the Device Manager. The update seemed to go through, but then the previous driver was still shown in the M-Audio control panel.

I took the plunge, uninstalled the 1.0.2.6 driver, rebooted and installed the latest one. But now the previous driver is still shown in the M-Audio control panel. I'm beginning to think the latest release is not in fact new, but is just the previous release with support for earlier versions of Windows removed, hence the much smaller size of the download file.

I have the same problem...

IIRC this happens when updating the M-Audio control panel itself too. I haven't tried very hard to solve this, but I think I tried a clean install the last time (maybe it just wasn't clean enough )

Btw: I just noticed, that this driver seems to have solved my problem with an extremely annoying buzzz sound, every time I start a video file of some kind.

Now I can´t test new drivers...


Any improvement in Digital mode at Windows XP SP1?

What about that strange "strong noise" reported when pausing in Fb2k Kernel Streaming?

What about performance in TheaterTek?


And ASIO? It will be implemented this year? (or century?)

Here it shows 1028 in c/p,and i didnt loose my settings..

This is the reply I got from m-audio: "This actually just a bug with the Revo control panel displaying the wrong driver number."

But then I check my device manager, it says driver version 5.10.5052 (which is 1.0.2.6)

Can someone translate what is written for 1.0.2.8 on http://www.midiman.de/d_revo.htm

It says that 1.0.2.8 is identical to 1.0.2.6, so that if you already have the latter installed there's no need to install the former. I must say I had already come to this conclusion.

Does it say why they released an identical driver as a new version?

EDIT - Google translation

Revolution driver for Windows 98SE/ME/2000/XP. The driver version is identical to that of the predecessor package 1,0,2,6 and for accordingly necessary for systems to this driver version not. Again in this version: the Installationsroutione was revised. During a driver actualization the old drivers are removed automatically. The drivers can be removed completely over system control >Software.

It seems only the installer was updated..
