Hello all. I also have a problem calibrating my soundcard. It always indicates the error "very low signal level". I have a built-in audio from the motherboard. Is this not good enough? The motherboard is the GIGABYTE GA-MA78GM-S2HP

I appreciated any help. thanks.

Hopefully you have the loopback cable in place and are using the correct splitter adapters.

Are you observing any input VU meter level at all?

brucek

Yes I have the loopback cable in place and have the correct splitter in place.

I don't know how to include the picture of the VU meters but on the "out", the level says -4.0 on top and -7.0 on the bottom. I have a left and right VU meters on the right side of the "out" meter and it averages -65 on top and -75 on the bottom.

I have placed the out splitter on both speakers out and line in slots but still no success.

Any more ideas? Is my sound card not good enough?

I'm using windows vista.

Line-in is selected, unmuted and on max. I do not see a playback line-in. Tried every combination out there.
I followed the instructions to the letter. One thing I don't see is the wave volume setting. Don't know if this matters.
I also tried the "use left channel for calibration setting". Same results.
My soundcard is functioning well as I watch movies on the HTPC.
When I try to calibrate, I only use the stereo settings.
Is there any settings within the REW that I missed?

So you are linking the green output jack to the blue input jack on the rear panel connections? If you leave the green output jack connected to your front speakers can you hear signals if you use the REW signal generator?

Just tried it and yes, I can hear the signal.

 

[hanggaw]

OK.

Usually Vista won't allow REW selection to the soundcard (as in XP) and so you must have the card selected as Default in Windows.


The Windows devices menus for Record and Playback should show the line-in muted for playback and unmuted for recording as show in the example jpgs below.

If that's all fine, then you have a problem likely with the cabling or stereo adapter you are using to break out the right and left channels.

Can you show me a jpg of your REW Settings page?

Checked the settings and they're ok. Changed the cables several times. same. Should I be using mono jacks instead?
Having a hard time uploading pics. Sizes are too big. will do it again later.

Here are the pics.
What software do you use to capture the screen images anyway? Thanks.

Windows Paint is the easiest. Simply select whatever application you want captured on the screen with your cursor and then press Alt plus PrtScr keys. This saves the image on the Windows clipboard.

Start Paint and paste the clipboard into it and save as a jpg file.

Well, everything looks fine, so you've stumped me on this one. It simply looks like the line-in is not working, for some reason. I have no idea.

brucek

Thanks. For the help. I really wanted to make this work. I guess I will just try one of the USB soundcards.

FWIW- When I tried on my system, selecting "Default Output" and "Default Input" in the settings, I could not get a reading. I had to select "SPEAKER" and "Line_In". Also every time I brought up the settings screen, for some reason it would disable the Line_In input on the Windows Mixer.

Yep I tried every possible setting combination on that too. I tested my line-in with a signal from a CD player. REW and windows both acknowledge the signal. Used the same cables too. Unbelievable. Still nothing.:gah:

 

[hanggaw]

So if you can hear the test signal on your speakers from the green output connector and you can get signal level on the blue line in with an external source, the problem has to lie with your breakout cables. Are you sure they are stereo breakouts at the jackplug end, not mono?

Yes they are stereo...and these breakout cables were the same ones that I used to test the CD player from the RCA outs. I'm really going nuts with this.

Anybody has a similar soundcard or motherboard? Maybe one of these (realtek alc889a) does not support loopbacks?

 

[hanggaw]

Hi,
perhaps there is a monitoring option which is activated/inactivated. Look at your Sound-Configuration Record -> LineIn -> LineIn-Properties -> Advanced (or General). Maybe there's the reason why...

There is a setting in the LineIn enhancements titled " DC offset cancellation". I tried using with this on/off to no sucess. In fact, i tried all settings possible here.

 

[hanggaw]

Yup, I have tried all of the devices available in the pull-down menu. Still not working. I tried the software with Windows 7 just in case it might help. Nope. The only work-around left is to get an external soundcard.
