[opensuse] Compaq Presario V3040TU headphone jack and speaker sensing problem.
Hi, I got another problem on my laptop. My speaker and my headphone jack got no problem. Both got sound out. But the problem is when I plug in my headphone to headphone jack, my speakers still get sound. What happen actually? Sensing problem?

What you have here isn't a software problem, it's a hardware problem. If
the problem were in software, we'd have reports of this problem affecting
all manner of laptop computers. The 3,5mm audio jack is a standard
component, and the way it knows to switch off the speakers is a tiny
microswitch at the back of the jack that is pressured by the end of the
audio plug.
I suggest you have a techie look at it, esp. if the problem is not
reproducible on a computer of similar configuration (which I guess the ML
will tell you).
Good Luck.

Nope, not true Horst. This is no longer done with microswitch, but rather in the sound chipset. I would bet dollars to donuts that this is a Intel High Definition Audio chipset (often referred to as sigmatel) , a true piece of crap if ever one was invented. If the O.P. gets the latest Alsa, either in rpm forma or compile from source chances are the problem will be solved. Its a well known and often posted problem on this board. -- _____________________________________ John Andersen
