Line selection

The default line selection setting is shown below.

The purpose of this setting is that WinMLS will make sure the volume is set only for the selected mixer line (for example line in or microphone). But it has been reported that this default setting will not work on a few sound cards (some of the Sound Blaster cards may have this problem). Therefore when you start measuring, if it seems impossible to control the input or output volume from WinMLS, try one of the other alternatives that are present to handle bugs in the sound card drivers or operating system. We also recommend that you read the Specific sound card settings reference section. It should be possible to work around most problems, especially if you inspect the Sound Card Windows mixer while trying the different alternatives. Otherwise, the WinMLS mixer line selection can be turned off as explained below.

If you have followed the procedure in this section, the sound card settings should now be correct. Click  to close the Sound Card Settings dialog.

Now store the changes. Go to Setup->Store..., make sure the setup name is ‘Sound Cards_Default’. Click the  button to exit the dialog.
