combination of the ASUS control panel and Windows
Mixer to configure the sound card. The input and output jacks to the
sound card must be plugged in before
Windows Mixer will display the input or output as active and allow
adjustments. Even dummy plugs will work, but something must be plugged
ASUS Control Panel
Change the settings in the control panel to match the above pictures. You may have to click or right click on the input and output icons on the left to obtain all the correct choices. The important settings are to select the Line In option for input (as opposed to microphone. The output should also be checked. It can be either headphones or speaker. Sample rate and bits should be set to 192000 kHz and 24 bits. Make sure input sliders are set exactly the same for both channels (they normally track together).
If your ASUS control panel does not look like this, use the U5/U7 Sonic Studio setup procedure on this page... http://www.telepostinc.com/asus_u5_u7.html
Using Windows Mixer
The mixer panel on the left is accessed by right clicking on the little speaker icon in the toolbar at the bottom of the Windows screen. You will be given several choices after clicking. Choose the one labeled Recording Devices. Scroll up and down until you get to Asus Xonar U7 Line In. Click on the entry and then click on the Properties button to open the Line In Properties window. Click on the Levels tab and use the slider to adjust the audio input level to set the proper ;eve;, approx. 20%. Right clicking on the little speaker icon to the right of the level value will allow you to choose between percentage gain (shown) or dB. Right clicking on the Balance button will allow you to adjust the left and right levels, but normally they will be with 1% of each other and well within the range of the SDR image canceling system.
The advanced tab allows you to set the maximum sample rate for your sound card. It's not required in order to use the Digital Level Meter, but will probably be required to make sure that the mixer works at the full bandwidth of your sound card. Lower left is what it looks like when choosing the setting, and lower right after it has been chosen...

1. Right click on the Line In icon
to bring up the Line In options (brown area). Left click on the Volume
Control option to
choose Volume Control. Set the sliders to between 10% (-20 dB) and 50%
(-6.02 dB). Higher values increase sensitivity slightly, but increase
the noise floor at the left and right edge, along with adding some
spurious spikes. Lower values produce a flat noise floor, but reduce
sensitivity by 10 dB or so. The
values are the same ones that appear in Windows Mixer, BTW.
