My new PC only has one headphone jack, preventing me from using both my mic and headset simultaneously. On my old PC, I used an adapter that combined both jacks into one, allowing me to use my headphones with both audio and mic functionality. However, on the new PC, I can only hear audio and cannot speak through the mic. Despite searching for solutions, I haven't found any. Is this a PC hardware issue or a Windows issue? Any help resolving this would be appreciated.
