No win 7 qualified drivers for your M-Audio Revolution 7.1 at M audio I logged in and checked Good news is I found some drivers.info below.
We have some m audio stuff and Avid pro tools here their legacy and new support sucks btw. out of all the people we deal with they have to be the worst even Aurturia all the way in France is much better except the time difference thing there are work arounds to get unsighned drivers to work but I don't like to invoke those that would only be a last resort but I would probably just get anothercard if it went that far. or put it in a nix box
Try the m audio vista x 64 driver below first if it doesent work or if you are on 32 bit windows just use the via chipset unified drivers further below
follow the procedures below exactly for either the m audio drivers or the via unified drivers
If it works fine ,if not remove it try the drivers from via below. You have a VIA / ICEnsemble's Envy24HT audio chip. the brits @ tech reports think it's pretty tits up btw. they like that m audio card .
Drivers below are straight from Via they make the controler chip on the m audio card .it's a unified win 7 64/32 bit driver and should work fine I'm sure Via had M$ sighn off on it chip mfrs are are usually pretty good about that stuff.
ODM chips are used in many different products and the vendors usually modify these drivers with whatever branded GUI eye candy they want to use they should othewise be fully functional .
First try these vista 64 bit drivers from m audio read procedures below and follow them exactly if after a few tries and if they don't work move on to the Via chipset drivers below These are the M audio Vista 64 drivers http://filedir.com/drivers/sound-card/m-audio-revolution-7-1-soundcard-driver-5-10-00-50-download-307742.html
download links are clean work fine and tested ok.
Read procedure below
Audio's Revolution 7.1 sound card
Unified via Chipset driver
Via / ICEnsemble's Envy24HT audio chip
via chipset drver unified win 7x64 and win 7x86
Follow this procedure exactly
*usually same for any sound or video card (well mostly for video cards anyway)
1 first disable on board audio in bios
2 remove any sound card drivers from device mgr
remove sound card shut down
3 load windows with no card and on board disabled
4 install drivers shut down install card
5 load windows you might have to do this exact thing (uninstall hdwe and drivers ) 2 or three times to get things working fist try re botting 2 or 3 times between driver re instals welcome to microsofta window ! world I'm sure the via chipset drivers will work
Just be glad you are not using ***nix with unsuported hardware and don't have to compile your own drivers but that's another, story Windows is cake by comparison .
I use chipset drivers all the time when vendor drivers are buggy or outdated especially on videocards or wireless.
If for whatever reason you decide you don't want the m audio card although it might be better for critical listening get an xonar DGX or something similar .
no need for an expensive card if you are not using the DAC or audio you just will use the controller and PCIe buffer anyway .
The M audio controller can sample 24/192 data and can output 24/192 to the DAC only the ADC is limited to 24/96 you aren't using that anyway with coax or optical outs . the 24/192 will pass through uninterrupted to PCM output optical or coaxial it will never see the ADC.
The 24/96 limitation applies in this case only to ADC in the analog audio output signal path that's it.
The m audio 24/96 ADC will only be used if recording audio or playing back audio directly from the card line level
or speaker /HP analog outs even though you likley coulden't hear the difference anyway belive me I've tried with a studio full of pro equipment not scientific testing but lets just say an informed opinion for pourposes of discussion. IMO the returns diminish greatly after decent 16/44.1. I think Room treatment decent speakers corrcet placement,distributed bass,taming room nodes and room treatment there I said it again will get more results in the end.
None of the mainstram studios are doing much 24/192 music until they get the content creators and producers
on board it ain't happening much and what little is out there will be expensive . more than half of it if it is recent is upsampled 'remastered' digital anyway you if can find some that is re mastered from
original master tapes or copys that will odc have to be older content and will be the exception rather than the rule. even then the re mastering has to be done well .
remember SACD ? I still have some and a nice Sony ES spinner packed in the storage bldg. decent 16/44.1 CD can sound just as good been there done that.
no point in a 24/192 in your computer unless you put a BD drive in it even then the m audio will be fine it can read it .
here is what the folks at tech port say about the m aududio card
The most important specification to note is the lowest level of internal precision supported by each sound card—the weakest link. Fortunately, the Revolution 7.1's weakest link really isn't weak at all. The card's Envy24HT audio chip has a maximum internal precision of 24 bits at 192kHz, which is better than even Terratec's DMX 6fire 24/96. (The 6Fire uses an earlier of the Envy24 audio chip that tops out at 96kHz.) Though the Revolution 7.1's DAC shares the same 24-bit/192kHz sampling rate as the card's audio chip, the ADC is limited to 96kHz. The Revolution 7.1's slightly lower maximum ADC sampling rate won't hinder audio playback at all, and I would imagine that 24-bit/96kHz ADC precision should be enough for even picky audio recording enthusiasts.
