Today when i am using my mbp 2015 retina , sound went off suddenly.
Internal speaker or headphones are silent. I can only get sound from hdmi output.
- Sound settings seem ok to me.
- Some unspecified Diagnostic shows no problems.
No red lights in headphone jack.
I have reset the nvram and smc. With headphones, 8 hear sound just for a second but that fades out very quickly. I am running OS X mojave and don’t know how to fix this.
