Product number of my laptop: QA944EA#AKD
Operating system Windows 8.1 Pro 64 bit
Problem:
Speakers do not play sound unless i plug in headphones. When i plug in headphones both speakers and headphones play sound. When i turn off speakers and plug in headphones none will play sound.
Description:
When i have headphones not connected to my laptop, there is no sound at all. I see green bars (the sound level indicators) in sound mixed under Speakers/HP but the sound is not playing.
When i connect my headphones in the sound is coming from both speakers and headphones. But there is no "green bars" moving next to speakers icon in Control Panel -> Sound (which indicates the sound level in device). The sound also appears in speakers when i plug in a jack into microphone plug (i have two headphones plugs and one microphone, tested both headphone plugs with several headphones).
The strange thing is that when i for example enter to playback devices and i select headphones "communication device" and select "test" option (the one that does short ding ding ding sound) suddenly sound comes back to speakers but as soon as the test is done (that short ding dong sound) speakers go dead.
Same happens when i go to Sound mixer and from view where i have Speakers/HP, then System Sounds etc. i sleect device to communication headphones and for example change its sound level, suddenly speakers play music for a while and when i stop adjusting sound level of heaphones they go dead again.
Another strange thing is is that when i run a test on Speakers/HP (in sound in control panel) it loks like the speakers and communication headphones are linked together because if i right click on them durin test instead of "test" option it displays "stop test".
When i turn off the speakers in Playback devices applications (like winamp ) crashes and returns errors. Also the windows sound mixer becomes unavaliable like if there were no playback devices (even if my headphones are still plugged). After that even if i play sound and i see green bars next to communication headphones (in sound<- control panel) the sound does not come out of headphones.
I also made a test, i removed all devices from device manager audio input/output and when i refreshed it automatically finds 'stereo mixer', 'communication headphones (even if my headphones are unconnected) and internal microphone , and when i connect in my headphones windows is installing External Microphone instead of headphones???? (checked with other headphones too).
Below are some photos of what im doing:
At 1st you can see how it looks with headphones unplugged. There is control panel -> sound menu opened and there is Speakers/HP icon and Communication headphones Icon, also there is mixer. You can see green bars because im playing sounds all the time but they dont come off the speakers at all.
At 2nd picture you can see that in Device in mixer i can select Speakers and Communication device. At 3rd picture you can see how it looks there. Speakers/HP bars are still green, the music is playing but is not coming out of speakers BUT when i start sliding the volume lvl slider in sound mixer under communication headphones a sound comes out of speakers only for the time i do it. When i stop clicking there it goes silent again.
4th picture shows my device manager, you can see Speakers HP, Stereo Mix, Communication headphones, and internal microphone. I went there and try to disable them all/uninstall but somehow when i plugged in headphones sound was coming out (both of headphones and speakers but not alone speaker with unplugged headphones).
What i have tried so far: Uninistall driver from device manager and have it find it again , uninstall IDT HD Audio from add/remove programs, restart computer, update windows with windows update, look for updates in HP support assistant. Turn off my computer, remove battery, remove power cord, press the power button few times to make sure everything is discharged and install battery again. I also tried the windows troubleshooing from control panel for audo playback.
Of course nothing worked as I am here now.
Any help appreciated. If there is anything i have to check/do in order to help with troubleshoting, please let me know.
