I recently got a HP Envy 4 Ultrabook 1002TX and have a very annoying issue with the sound.
- The laptop detects the headphones as plugged in when they are not. (Because of this I get no sound)
- When I do plug in headphones, it detects the headphones as being plugged out, and I get sound from the inbuilt speaker. (Doesn't matter if they are headphones or external speakers).
- When I plug in both a headphones set and a microphone, the laptop detects both of these as properly plugged in and outputs to the headphones and get input from the microphones.
I am not sure if this problem existed when I bought the PC, since I forgot to test the sound then, but it was definitely there from the first time I played some music.
Also, I dual boot windows 7 and ubuntu 12.04 and the same problem, ( all 3 parts from above) exists in both OS'es.
What could be the issue?
PS: I am guessing hardware or BIOS. The BIOS says it is the latest, i.e. F.OA, according to the HP site. Is this actually the latest BIOS release for my PC?
