For example, you may see the Intel GPU with EFI boot, which is not mean to be seen. Your Cirrus or Realtek Audio devices do not show up correctly.
First: Volume & Headphones Before you spend all day resolving a non-existent issue, check that you have one at all. Adjust your volume (make sure it’s not muted) and check your device’s audio out port doesn’t have any earphones or other external devices plugged in. You can’t play music from your internal speakers while another output device is connected in this port.
Check Your Sound Settings Head to System Preferences Sound Output (you can search for it using Spotlight too) and check your sound settings for discrepancies. If you’re using a laptop, you’ll probably want to choose “Internal Speakers” (or “Headphones” if you’re using them). You may also see “Digital Output” if you’re not on a laptop. Make sure the desired output is selected. Note: You can also open Activity Monitor and search for the coreaudiod process and If you want to be a fairly proficient Mac user, it is necessary to know what Activity Monitor is, and how to read and use it. As usual, that's where we come in.
If your issue still isn’t resolved at this stage, you should try a full restart. Reset PRAM & SMC There are many reasons you might want to Having trouble with your Mac?

Third Party Software Problems You may run into an issue where your sound works in all but one app, in which case you’ll probably have to define your desired output device in that app’s settings. This is most often an issue associated with audio and video editors, like Audacity and Adobe Audition. Instructions for each app will differ, but you’ll want to ensure you choose the same output device that appears in your Mac’s System Preferences Sound Output option panel. Some software may require you to, which allows you to use multiple audio interfaces at the same time.
Update Your Old OS Mavericks had a lot of sound problems, many of which cleared up with the release of Yosemite. Distorted, crackling audio and random periods of complete silence were not uncommon (killing Core Audio usually resolved it). You should update to OS X Yosemite if you’re still having Mavericks-era sound problems, particularly as 10.11 While the changes don't seem that big on the surface, there's a lot going on under the hood that could make this incremental upgrade one of the most significant to date. Before you upgrade your OS make sure you’ve backed everything up, then head to the App Store and on the Updates tab you’ll see an option to upgrade to the latest version. The download may take some time, and once finished installation is straightforward. You can even It's really easy to save the macOS installer to avoid multiple downloads, and worth doing even if you only have the one Mac. Without having to download it again.
Microphone and Input Devices Just like output devices, input devices like audio interfaces and microphones can also be mis-configured. Head to the System Preferences Sound Output menu to define your output device. This particularly handy if you have connected a microphone and want to make sure you’re not using your computer’s internal one instead.
USB microphones and interfaces will appear here, alongside microphones connected via your audio port. Can’t See “Internal Speakers” or Other Outputs? This is a rare but fairly well-documented problem as asked on message boards and in blog comments with little in the way of a fix. It seems most common after performing an operating system upgrade, in particular the leap from 10.09 (Mavericks) to 10.10 (Yosemite).

Does anyone else use a Saffire Pro 24 audio device, or similar Focusrite/Saffire device for an audio I/O? Gradually over the last week it has sounded like my Mac's audio system has descended deeper and deeper into some global bit crushing filter. In other words, like it was losing bit depth! Very strange.
I'm not sure why this was happening. I was desperately flipping switches in the SaffireMix program that comes with the box, switched on SettingsSPDIF AC3 Device, then heard silence. Then switched it off again and boom, clear audio once again. Asking here because I think the problem might involve the computer itself, not just the saffire box. Also, I'm wondering if someone can't enlighten me as to the digital audio encoding/decoding processes, and what better a forum for that than stack overflow!
Hey, i'm the person who asked at stackoverflow. Checked that just now, settings are normal (32 bit).
Tried 16, 24 as well. It's interesting - the problem only occurs with input into the Focusrite/Saffire device, and with output from system sounds, like iChat. In fact, when the iChat app makes noise, it crackles - but not always in the same way, and not 100% of the time. It might make a noise one time, and then the next, no distortion. I've also experienced a symptom where I'm working on a file in Ableton/Logic/etc, and over time, the distortion gets worse, until it's practically cutting audio out completely.
I tried another audio interface, a RigKontrol setup for Guitar Rig, and that also creates the same issue. I tried messing with the sample rate coming in, examined latency factors in Ableton, etc, and no luck. This seems to me like some buffer is getting overloaded, since it gets progressively worse when performing heavy audio operations, but I have no idea what OTHER buffer exists that I could check.
