No sound not the usual problems mac pro

[nracing]

hey guys, i just got a macbook pro. it came with no OS so i installed Yosemite version 10.10.2.

the thing is the macbook has not sound at all. no output device, i use the search tool here to look for something similar but i came with nothing, I've seen some solutions like erase some files, clear memory, etc but i don't hace the files that are mentioned and I've erase the memory a lot of times, i wonder if its maybe a physical problem with the audio card or something because nothing make sense anymore.

here is a shot of what my audio settings looks like, no output device, sound lock.

let me know what you think

thank you! 🙂

Have you tried restarting?

And have you made sure the 3.5mm port is free of dust?

For lack of better data to go with, I will just go with what we have ...

There is no "audio card" in the system, at least not in the traditional sense. It's a chip on the logic board. My suspicion is that your "new" system has been the victim of a drop, or a liquid spill. That's the most common cause of hardware issues encountered in used systems that are sold to unsuspecting buyers.

Most likely will need a new logic board. Cost can be up to ~$1000 USD (easily) for the part alone, depending on the model.

yes, good guess, the system suffered a drop on the audio jack part, but the funny thing is that the previous owner who was a friend had no issues with audio, when he sold me the mac (at an incredible price) he deleted the OS so i asked a guy to install the latest OS, so im also wondering if it could be an OS problem besides the obvious drop problem. if i take out the bottom part where the battery is everything seems to be ok visually.
