Hi, I have new Inspiron 5551 , it was okay for 2 or 3 months then I got on Ubuntu that left input speaker isn't work , when I made test for sound after I found change
I went to dell's site and tried to make diagnostic but not available for Ubuntu , so I tried windows 8.1 and installed all drivers then I tested the sound it said left and right are good but at me no voice from the left port for the speaker , also it can't run output speaker ,
then I made diagnostic on dell site it said left and right are okay as windows but the same thing , just right is working from it's port , the left speaker haven't any voice from it's port
* also the output speaker just can work with Ubuntu and just one that give voice the left output also isn't work
* the headphone is okay , the left and right are okay on Ubuntu and Microsoft windows
* Laptop is Dell Inspiron 5551, run just 3 or 4 months , OS Ubuntu 14.4 at first , now Microsoft windows 8.1 and it just for try not activated , the audio driver installed, the output speakers F&D t-2169 30hz-18khz are good on normal PC , the headphone Creative WA-2 okay left and right.
I want to know the reason and if I can fix it or must go to Warranty.
Thank you
