Have you checked that you can get Audio via the headphone jack via testing in System preferences > Sound? First thing is to check that and that it has the Headphones selected in Output and not muted. Is it just ESO specific or generally?MacBookPro, Mid 2012. Running Mavericks.
I have a Turtle Beach PX51 headset. I know this isn't a "PC" headset, but was trying to get an all-in-one or 3 systems in one solution. I wanted to avoid having to use 2/3 different headsets for my Mac, Xbox and PS systems. Anyway. I was able to get the headset working through a combination of Bluetooth audio for my TeamSpeak and Headphone jack for the in-game sounds, then one day my headphone audio just fell to Nothing! I can't get it back, I've tried the Audio Midi set-up. I see this is a common problem for the MacBook systems. Is there anything I can do other than getting a USB headphone adapter? I welcome your thoughts.
Looking around it seems the most plausible reason. Not sure I can offer any other advice other than checking Google for possible solutions. There seem to be some suggestions but I don't have a MBP to check myself.Yes, thanks. I do go into Systems Pref>Sound then select output HEADPHONES input my TB headset. I go into the setting in Team Speak and use my Bluetooth for that audio. I get both Audio streams, but I noticed about a week ago my headphone audio is VERY low. When I go into Audio Midi settings, I notice the gain setting stops at 0 and I can't get positive values.
This seems to be a well-observed issue with the MacBook Pros, but I cannot find a solution anywhere on the web. I've looked and looked!
