i tried speaker mod and i was curious how far i can get with watts
it worked with 5 w 4 ohm,but not with 30 w 8 ohm.
now i have no speaker output at all.
i tried 3 other speakers even standard ones and it didn't work.
what shall i do?

Edit:soldering those would solve the problem or it will burn my mobo?

Edit: If nobody finds a solution i am just goanna use a lm386 solering it's imput on headset soket and use hold switch if i want to use lm386 or simply headphones.

But i don't know if i have enough power from that headset output.

I will post if project successful.

hi it sounds like you blown the fuse or the sound chip i would have just stuck with the 5w and not push my luck and use 30w on such a small out put unless you had a little amp

i have seen no fuse on phat, sound fuse is just on slim.

i don't think it's the chip because my headphones work.

thank you very much, Modded Matt !

I did search but i could only find a post with the photo in my first post and i wasn't sure if that was the solution.

Sorry for that.
