HP Recommended
Product: Probook 4530s
Operating System: Linux

Hi,

 

yesterday I renewed CPU's and GPU's thermal paste on my Probook 4530s, however after reassembling again I encountered a strange behavior. Everything works fine except sound control.
When I have auto-mute feature (of speakers in case of headphones plugged in) turned on, then when I have headphones unplugged speakers are muted and when I connect them, output goes to speakers, but nothing goes to headphones.

When I disable auto-mute feature, then output should go to both headphones (when connected) and speakers, but it goes only to speakers in both cases though.

It seems like hardware responsible for identifying state of headphones (plugged/unplugged) is reporting exactly inverted situation than the one which actually arises...and I have no idea at all how this could be fixed up (and what could have cause it).

I already checked twice that everything is inside connected as it should be but problem stays.
I also found out, that if I'm inserting the headphone plug under certain angle and plug it kind of half of a way, the output goes to them at that position...however solving this issue this way isn't very practical.

I'm using Arch linux, however I already tried on several other live OSs and problem is same.

 

I will appreciate any idea or help!
Thanks, Alan
