How do I fix Asus UX32VD internal speakers?

Hello everybody,

I am new on ifixit & this is my first question, hope i'll get help to sort out my issue,

I am facing issue with my Asus UX32VD 13' Laptop, no sound coming from internal speakers!

The headphone jack used to work just fine & external speakers as well using headphone jack but I cannot play the sound from the onboard speakers,

Delete old sound drivers & reinstalled, update with new drivers, reinstalled OS Windows 7, 8, 10 but nothing worked, so its more possible my onboard speakers have hardware problem, is there any way i can fix this issue or take out onboard speakers from laptop & check them some how & confirm whether speakers die or issue is in motherboard?

any help will be high;y appreciated,

Thanks.
