Currently I ran into a wired problems, the sound device is as the following:
If the Realtek HD Audio 2nd output is default setting: Everything works well. On the contrary, the Speakers also works well, when I unplug the earphone.
If I don't unplug the earphone, I change the Realtek HD Audio 2nd output to Speakers without unplugging the earphone as shown above, the Speakers cannot work well (No sound). Even if I choose either option, it seems to have no effect. :(
Does anyone have any ideas on it?? Or Is this REALTEK DRIVER issue?
I don't know if this is issue is been resolved for you. But did you try to configure Speakers? I've experienced issues myself, and reconfiguring my audio device to stereo instead of 7.2 use my issues have been resolved. I'ts worth the try i guess :)
