Sound Card Calibration Help

I am getting a message that I have a low signal level. Not sure where to look. I appears that I have things hooked up correctly. I am not able to adjust input volume on the settings page because it is greyed out.

Here is what I have so far. The graphs tell me that I am getting a reading from the SPL Meter but is it strong enough?

Any Ideas what this means?

Here is the sound card calibration graph and the impulse graph. The would not attach to the first post.

Here are the missing graphs. Too big on the first attempt

Why is there signal on both the left and right channel. You should have a short cable going from the left channel line-out to left channel line-in. The right channel should be left open.

Adjust the input level with the Windows mixer..

What soundcard are you using?

I am using the Soundmax Integrated digital audio from my PC
It has a plug in for a mic, output, and what appears to be the input to the far right.


I have followed the set up diagram and i am using the stereo splitters in both the line out and line in.

Does the loopback connection split the signal for calibration?

I have also disconnected everything and only used the right(red) out and connected to the right(red) line in. I still show input to both channels. Hmm.

Could it be the sound card not splitting the channels?

Thanks

Or do you perhaps have 'monitor mode' turned on?

brucek

Where do I check for this? I do not see a monitor mode setting for my integrated sound.

It would be a feature of the Soundmax Integrated application itself that would be accessed from the Control Panel.

They sometimes have a goofy name for it like "what you hear", or "mixed", etc..............

Wow, that appears to be the issue. Line in was disabled. Now it is now enabled. I will give it another go.

Thanks

Careful - Line In should be disabled for playback, but selected for record. Worth posting screenshots of your playback and record mixer settings.

Also on your main volume control turn the Room EQ Wizard volume up full.

Thanks for your patience Bruce and John.

I had line in enabled for playback and record line in was enabled. This may be why I was having so much feedback.

Here are shots of my new settings. I will retry again.

When you select the Speakers in Playback, you want to set them to Default. Then when you select their properties, you want to be sure that the Line-in is disabled. When line-in is enabled in Playback, this is the monitor feature. You want it disabled.

In the Record properties, you want the Line-in enabled of course.............

brucek

In device usage there is no selection to Default and in properties there is no Line-in to disable.

I do not seem to be able to get there with this on-board sound card.

I can get there with line-in for record.

If Line In does not appear in the properties of Speakers that's OK. Re-enable Speakers, in the properties for speakers check that there are no odd controls on the "custom" tab (if there is one), make sure the levels are OK on the levels tab, and select the box to "disable all enhancements" on the Enhancements tab. Also disable enhancements on the properties for Line In and make sure the levels are OK on its levels tab.

Make sure the 3.5mm plug on your stereo splitters looks like the picture in this thread: http://www.hometheatershack.com/foru...on-basics.html
There need to be 3 connections on the plug, there are lots of "stereo" splitters that just have a mono 3.5mm plug that is linked to 2 RCA sockets, they are no good for this purpose.

Thanks, I think I am making progress now. I referred to another recent thread showing a comparison of a Turtle Beach card to the Vista card. I did find the settings to get it set up with no feed back.

I adjusted all levels on the sound card tab with good results and good graphs. When I get to the Make a measurement step and check levels I get a level is Low message.
The receiver volume is quite high and there is noticeable hum. When I turn up the receiver more I still get the Low Level message. Any Ideas on what I should try?

Are you checking the Levels with a Subwoofer calibration signal using a subwoofer with the mains turned off?

brucek

I dont think so, still using the noise from the main speaker. Its like at this point the SPL is not giving an accurate read to the line in on the sound card. I will see if I can post screen shots soon.

Just ignore the levels check on the measurement screen and see what levels you get during the measurement itself.

Ok, Here are screen shots of my settings and a graph. Can you see anything that is suspect to causing issues? The first step of the measurement screen runs the tone and says the level is good but when I go to measure this is the message that I get.

I will also mention that I have not been able to completely isolate the signal on the graph to one channell during the sound card calibration but the graph seems to look good.

On the playback line levels I have muted all the choices except playback volume control.
Thanks for the help! I have too much time in to give up
