Title:
Switching problem between headphone speaker and microphone to laptop
built in speakers and front mic
Status in ALSA driver:
New
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
If I connect my head phone to my laptop it doesn't stop my laptop
built in speaker. Headphone works properly but at the same time laptop
speakers also plays. Headphone microphone behaves as same way.
It supposed to stop as soon as I connect my headphone to my laptop
which is not happening. And when I will remove my headphone from my
laptop the sound should immediately go to my laptop front speaker as
well as headphone mic/ external mic to front microphone.
I'm to restart my laptop every time to switch between headphone
speaker and mic to laptop built in speakers and front mic or vice
versa .
I'm using Ubuntu 12.04
My Laptop Model is -- Acer Aspire 4930G
