Macbook pro has intermittent audio when watching video

My daughter's 2012 MB Pro has intermittent audio problems (speakers or earphones). We notice this more when watching Netflix. We have audio at first and then it goes away. We've seen a red light flash at times in the headphones jack but don't know if this has anything to do with the issue. When I run system preferences, normal hardware is identified but when we are having this problem, a digital setting but no speakers show. The laptop is running Yosemite and has had this problem on and off for some time.

I'm guessing we have a software incompatibility but would like to know if others have seen and fixed this problem?

Thanks, Dale

Hello dtsteele,

If you are seeing a red light in your headphone jack, that is a good clue as to why you are having audio issues. Take a look at the resource below:

Troubleshooting issues with no audio from built-in speakers on Macs - Apple Support
https://support.apple.com/en-us/HT203186

Check to see if a red light is lit in the line-out port. If so, your Apple computer may need service.

Contact Apple support for further troubleshooting assistance.

Regards,

Judy
