Q: Audio Line-in input and BT Headset output not working

Hi,

 

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 ?

MacBook Pro, iOS 6.1

    Hi Paul,

     

    I'm trying to route the audio from the Line-In to my Logitech H800 BT Headset (Listed in the Output). I have also tried the same thing (routing the Line-In) to my Internal Speakers with no luck either. Hope this helps clarifiying things.

    so, you want to route the signal going to the line in on your macbook pro to the input of your h800?

    It's cause Mac's don't have powered line-ins. To use the line-in the headset would have to have some sort of power source, perhaps through usb.

    No. That 's not the problem. Normal Line voltage is observed, so no amp is (or should be) needed.

     

    Also, the audio coming in the Line-In (1/8" jack on the side of MBPro when configured as an Input) is registering an audio signal fine on the input mixer. It also records fine. The problem comes when I try to route the audio back out to an Output (either the Internal Speaker or (Ideally) my Bluetooth H800 Headphones.

    ahh sry, thats how the line in works on my Mac Pro, I guess the Macbook is different. This is a program I use in conjunction with another called 'soundflower' to route my audio to all the places it needs to go:

     

    http://www.macupdate.com/app/mac/11333/linein

     

    If you need to run multiple instances, you can open up terminal and type

     

    open -n /Applications/[PUT PROGRAM NAME HERE].app/

     

    It will open up another instance every time you run that script.

    i'm not sure you can route any old audio to your headset. the headset receives only via bluetooth, right?

     

    the soundflower option might be able to do it as already suggested by akwandaltw.

     

    have you or do you need this?
