The Core MIDI (Musical Instrument Digital Interface) framework provides similar interfaces for working with MIDI data and devices. You can access the HAL using Audio Hardware Services in the Core Audio framework when you require real-time audio.

Audio signals pass to and from hardware through the HAL. In OS X, the majority of Core Audio services are layered on top of the Hardware Abstraction Layer (HAL) as shown in Figure 1-1. Core Audio in iOS and OS XĬore Audio is tightly integrated into iOS and OS X for high performance and low latency. Read this chapter to learn what you can do with Core Audio. It includes a set of software frameworks designed to handle the audio needs in your applications.

If you can't fix an important issue in your Mac, check out our guide for how to reset a MacBook, before you sell it or give it away. That included the speakers, which fixed the audio problem. We've got a happy ending, folks! When I took my MacBook Pro into a Genius Bar to get its battery replaced, the physical design of the laptop required the company to also replace most of the parts in the top of the notebook deck. Oh, and this doesn't make me feel too confident about how many more months my MacBook Pro has left, so I'm making sure to back up my Mac. Now, I've got even more reason to get a new MacBook and I'm hoping that the rumored Retina MacBook Air actually comes out, as I'm well out of warranty.

I've reached out to Apple and will update this story if I get an answer. This is not a true fix it's just all that I've been able to do. Yes, using only one speaker means I have less sound coming from my laptop, and I don't have stereo sound anymore. I heard no distortion when the audio came only from the right side. I then loaded up the musician DRAM's "Broccoli" - a particularly bass-heavy track - and slid the Left-to-Right audio balance slider. To find that, open System Preferences, click Audio and then click Output. Then, I saw a suggestion to use the audio balance slider to find out which speaker was busted (if it was only one). After I copied and pasted those three words into a new Terminal window, hit Return and typed in my password, the sound quality remained fuzzy.Īnd while those solutions didn't work, I provide them here in case any of them work for someone else. The final fix I found online suggested opening Terminal to run the command sudo killall coreaudiod, to discover if the issue was rooted in Apple's Core Audio, a low-level API that manages sound. Unfortunately, videos and songs sounded equally bad on the guest account. If Guest isn't available, open System Preferences, click Users, click Login Options and enable guest login. To do that, you restart your computer and select Guest when logging in. The next suggestion had me sign on as a Guest user, to see if the issue was limited to a setting for the account.

The first trick I found was to reset the NVRAM and PRAM, which you do by booting the computer while holding down Command, Option, P and R, until you hear two chimes.īut as those two chimes rang, each with the same distortion I'd heard before, I knew that wasn't the right trick.
