Keep your system up-to-date and out of trouble.Download: For newer Macbooks: Incase the above download link does not work, google “CirrusAudio.10.6.1.zip”.As we know, sometimes a simple restart can fix some minor glitches, including audio issue that Mac sound is not working. If the progress bar is moving but you don't hear anything, there is definitely no sound. Play a music to check if the Mac really doesn't play sounds.There are two variants of the driver included: Cirrus Logic High Definition Audio MacBook Cirrus Logic High Definition Audio MacBook, No S/PDIF Out. New drivers are available from Cirrus Logic. If it's on, it thinks you have a S/PDIF connector plugged in and audio will never work until you fix that.Windows XP driver 1.0.0.32 is not fixed, while 1.0.0.38 appears to fix audio playback but not recording. Apple has tweaks in them that break if you download a newer vendor driver (like the screen brightness keyboard buttons or volume buttons).Īlso note: Look inside your headphone jack to see if there is a red light on in there. NOTE I would uninstall the Realtek driver you downloaded and just rely on the BootCamp drivers. To choose one, just select it and hit the Set Default button. It should just be a matter of figuring out which one output is going to. Under the playback tab, it will show all the output devices available: To change it, open the Sound control panel. The wrong one is probably selected in Windows. Anyway, only one output can be active at a time. Also, the discrete GPU can send audio through the Thunderbolt port, but I don't know if 2010 models have Thunderbolt. Mac laptops have three different audio outputs the internal speakers, the headphone jack, and the S/PDIF output (a digital fiber-optic connection that is also inside your headphone jack). Is there anything else I can do to fix it? I've also tried my headphones and had no luck with those either. Even when I go to configure my sound in the control panel (when I have a YouTube video playing) the visualisers (if thats what theyre called?) appear to be moving, as if to suggest that my system can detect the sound, but without anything actually coming out of my speakers. I downloaded a Realtek driver for Windows 7 (two in fact, alas one didn't appear to be compatible and wouldn't install) and installed it successfully. I read that MacBooks typically have Realtek sound cards in them. When I double click on one of them, it says that the device is working properly. It has this listed about 5 times in fact. When I look in the device manager and look under sound, it says the following: I think everything installed correctly except for some drivers (bluetooth etc) but the main thing that bothers me is that the sound isn't working.

I have installed Windows 7 on my 2010 model MacBook Pro using Bootcamp.
