I do not believe it has speaker level output, only line level output for feeding the powered speakers.

BUDM on U26 pin 35,36 , 37 , 38 are the same?
its this chip doing the output for the speakers?

I have replaced U26 with a new one but same issue. That was the first ic that came to mind but that is not the case.

Check the amplifier (U29 - TPA6017) if it is receiving signal from U26.

Sorry. I only replaced U29 so I guess I should do the same wth U26. @whaldsz, I will replace as I have no tools to test signal.

try replacing stereo jack. as far as i know, if plug is removed, the signal will be redirected to line going to speakers. there are switch inside the jack to mute speaker when stereo plug is inserted.

correct me if im wrong

apparently yes!
I had a acer that did the same thing.
it work with headphones but in my case it could have been the jack that did not unlock the internal speakers from that jack.
