I've got both my Jabra GN9350 and my laptop speakers playing audio at the same time. :)
Here's the trick (and it's been verified on 3 other Win 7 systems):
- R click on your speaker icon, select 'Recording Devices' (if you have the sounds dialog up, it's the 2nd tab 'Recording')
- R click in the white space, be sure that BOTH "show disabled devices" AND "show disconnected devices" are checked.
- **Now this step is going to take a little bit of thought for each computer being used: on my laptop (HP Elitebook) I get a device "Stereo Mix", ENABLE this device.
- Click on Properties, go to the tab 'Listen'
- Check the box "Listen to this device", also change the drop-down box below "Playback through this device" to be your second audio device
-- To verify that you've done this correctly, go back to the Sound dialog tab Playback, you should now see both of your audio devices showing the little green graphs moving.
Here are the specific settings that I have on my laptop, maybe this will help with your settings:
Speakers- GN9350 (Default Communications Device)
Speakers- SoundMAX Integrated Digital HD Audio (Default Device)
Stereo Mix- 'Listen' feature points this device to my GN9350 headset.
