internal speaker not working

Is there a red light in the audio output pot?

Ciao.

The red light indicates that the internal switch is stuck. Try the following:

Insert the earphone jack a few times.

Blow into the port real hard or use compressed air if you have it.

Insert the earphone jack and hold a volume function key (F10, F11 F12) and withdraw the jack.

Use a cocktail stirrer or toothpick and wiggle it inside the port.

Ciao.

If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. If not, the machine needs to be serviced. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.
