No sound through headphones and speakers
Since some time I suddenly have no sound through the headphones output nor through the internal speakers.
When you look at sound settings in system preferences, no internal speakers are shown nor does the headphone output show when something is plugged in.
Do get sound through USB->external audio-bridge but lately the sound is getting distorted more and more and at random.
Tried all I could think of and what was suggested online; PRAM reset, SMC reset, pick tooth in headphone bus, even a rain dance and more.
No success :-(
I slowly suspect that the sound card is broken.
Could this be the case and can this only be repaired by completely replacing the logic/motherboard because the soundcard is integrated with it?
