I'm trying to run the Line-in into my MBPro and route the output to my Logitech H800 BT Headphones at the same time (a pass through), but can't get it to work.


I have tried to run the line-in to the Internal Speakers and can not get this to work either.


Steps to taken:

1. Go to the Sound window by selecting the Sound icon from System Preferences.

Next, I route the Line-in by:

2. Selecting the Input button from Sound Effects, Output, Input buttons.

3. Select "Line In" from the Select a device for sound input list.

4. Select "Sound Input" from the Use audio port for drop down list

5. you should see activity on the Input Level.

6. Next, select the Ouput button from Sound Effects, Output, Input buttons.

7. Select "H800 Logitech Headset Stereo (or Internal Speakers) from the Select a device for sound output list.

8. Verify that "Sound Input" from the Use audio port for drop down list is still selected.

9. Also, verify that the Mute checkbox is not selected in either the Input or Output window.

10. NO SOUND :-(

11. If I pull up a radio station in a webbrowser, I can listen to it without issue. So, I think audio out is set correctly.

12. If I install Audacity: 1) It shows the audio input and output to be set as above (Built-in Input/H800 Headset). 2) If I record and then playback, it records the audio going in the Line-In and plays back accross the H800. 3) Also looked for a Monitor function in Audacity but could find one to test simulataneous I/O. 


Any idaes welcome ?
