Forget this--the problem's in the headphones, not the computer.
I recently upgraded my Inspiron 3505 to Windows 11. Now, my headphones only play the right channel sound, not the left. I've tried switching between Realtek sound and High Definition sound, but I still get only the right channel. The help literature suggests using the mixer, but I can't find it; I can't even find the "Speakers" icon on my taskbar (including the "hidden items" area). How can I get the beastie to play stereo?
