Hello Stefan,

I would suggest a clean re-installation of the audio drivers. That is, uninstalling and re-installing the audio drivers: 

1. Open Device Manager (Start -- Control Panel -- Device Manager).
2. Expand the tab for Sounds and right click the sound card. 
3. From the drop down menu, select “Uninstall”. 
4. Ensure to check the box “Delete driver software for this device”. 
5. Restart the computer. 
6. Once the drivers are unistalled, re-install the latest drivers from Dell Drivers and Downloads. 
7. Restart the computer and check the functionality.

Hope this helps!

Hi Allan,

thank you for your answer.

I have it made - the result is the same. BUT i have found another issue to solve it without take off and put in the cable:

When you make a double-click under the loudspeaker-icon from Waves Maxxaudio 4 and go to "extended", "Connection Info" and

change the Headset to loudspeaker - it runs.

I think, the error / problem has to do with the one jack for Headset / microphone. Tomorrow i will buy an adaptor for this to change the

one jack to two - separated for microphone and headset. May be, this is the solution.......

Let´s see - i will give you a comment.

Thanks again

Stefan

Excuse me Allan, but i have tried to buy on the weekend the cable / adapter but without any success.

I am living here in Mexico and it looks like, that it´s very difficult to buy this kind of cable......

I am searching for other shops. Gives it a possibility to buy it directely from DELL???

Greetings

Stefan

Thank you - i will search about this.

I also know, that may be isn´t the right solution - but it looks like this problem..... lets see and think positive :-)

Hi Stefan. I don't know if the cable/adapter you are searching for will solve your problem, but I can provide some other information about it. Dell does not sell it. Search for it under the name Headset Buddy. Here is a picture of it. Notice the 4 segmented plug -- that is what you need.

There is another Headset Buddy model that has a 3 segmented plug -- don't get it. Picture below of the WRONG one:

Hello Stefan,

I apologize for the inconvenience. As Jimco said, this cable is unavailable with us. However, you can find them at Amazon.
