Can REW use a digital out ?

I searched the forums honest....

I seem to be able to run REW just fine under Vista 64 bit however I can't get any sound via the digital output to the receiver. My PC is about 40 feet from my receiver and I've run a digital output to the receiver (SPDIF) but no analog. Choosing the digital output or setting Vista to use the digital output and selecting the System Default output results in no signal from REQ at the amp (though Vista sounds play fine). I may have some extra RCA cables of the needed length but before I go to the trouble of hooking them up I thought I'd just stop and make sure I wasn't missing something obvious?

Well, it can, but you don't want to do that since you won't have a soundcard calibration file working to keep the results of your measure accurate.

REW has the option of using the left channel as a soundcard calibrator or you can create a soundcard calibration file on the right channel and store it.

Either way, it assumes you're using the analog line-in and analog line-out - not digital.

What trouble? Just move the SPDIF cable over to the receiver’s and soundcard’s analog connections. One connection is all you need... :innocent:

Thanks for the welcome, I've been lurking even before I created a userid....

Guess I should have mentioned it's an optical connection... (for 45 feet of cable running along side mucho other electrical interference it seemed the way to go).

If your cable works for other audio on your computer, then your cable is not at question...so don't even bother thinking about replacing the cable.

REW works with digital output, but then the calibration file becomes a bit more interesting, but that's a non-issue until you get your audio running.

In your REW setup, have you tried manually setting the audio inputs and outputs?

Yup, every single possible way.

I recently did the Vista SP1 upgrade; reading a bit I've found people having to reinstall the audio drivers to get some apps. to work properly so I'm giving that a try as I type. Won't get to test until tomorrow though, every one else is in bed...

Not that I can actually help here, but just for the record, I had no problem getting vista to output over toslink to my avr... I was using a Soundblast Live! 24bit External card...

I'm not having any problems with Vista either, just REW, but I assume that's what you meant? Just for the record have you applied Vista SP1 and are you running 32 or 64 bit Vista?

Got the Audio driver swapped back in but haven't had a chance to play with REW again; too much Easter craziness yesterday, friends over for dinner, late night, blah, blah, blah. Hopefully know more after tonight...

Well replacing the Vista audio drivers did not help. Pretty sure this is a Vista issue; I can see the volume indicator in the Vista control panel start to respond when I launch REW so Vista apparently thinks it's processing an audio signal. The test signals from the same control panel are audible, the signal from REW is not. I'm using the onboard Realtek support and I've tried both the drivers that came with the MB and the newer versions for Vista 64 on the Realtek site. Anyone else here had success with REW running on Vista 64 bit and if so with what audio support?

Hmm, I've been attempting to use the "Digital output Device" similar to your last option in the primary sound control panel (setting it to default or selecting as the output in REW). I don't want to run the speakers attached to the computer, they're across the room from the main speakers but would still be audible so I haven't checked if there is a digital output associated with the control panel attached to them. Guess that will be on my short list of things to try tonight when I get home.

Thanks.

OK, double checked. No digital output options associated with the speaker properties when using the Realtek. Have to stick to purely to the Digital out. Canadian_dude, if you see this can you tell me if you use the digital output can you get a signal at the receiver? :scratch:

(BTW, I'm originally from Canada myself; southern Ont.)

Some more exploring reveals that my install of Vista does not recognize that I have the SPDIF output on the machine, the driver properties show it's using the ATAPI mini jack. Given the fact I can get Vista to play sound via the SPDIF output I'm not totally convinced that the issue, but I'd be more comfortable if someone could confirm that? Alternately, can someone suggest how I might get a SPDIF output added to my Windows Sound control panel options?
