Hello Everyone
Last week I was changing my Graphiccard a few times to test another one and finally installed my old one back in. After I restarted my Computer all rear audio jacks as well as the front audio jacks stopped working. I can safely say, that it is not an issue with my Speakers.
I already tried uninstalling and reinstalling the Realtek HD Audio drivers numerous times, everytime getting different results. Sometimes the Speakers are not visible at all on the choose audio output screen and sometimes they are, but they never seem to work. My Headset( Connected via USB) and my Monitor speakers( Connected via Dvi to HDMI Cable) work fine. There is also at all times the Realtek Digital Output listed, which I don't know the use of.
Inside the Realtek Audio Manager i can only choose options for the digital Output. When i chose to disable the front jack recognition inside the Manager the speakers would show up, but the test sound didnt give any sound whatsoever. However when plugging in headphones to the front green jack, the speakers started a deep humming sound. I could even control the volume of this sound with my computer volumesettings.
Here the front jacks arent visible because i disabled them, without any progress, in the bios.
I also had a look at the cables connecting the front jacks with the mothereboard and made sure there was no loose contact. The speakers are connected to the green audio jack. The volume on both the speakers and the pc is turned on. Before the change everything was working fine.
Is there any way, without buying a soundcard, that can fix my issue?
