Running Xcode 12.0 simulator causing cracking speaker sound (MacBook Pro 2020 13')

I am going to test this out. I have the same issue, happens allot, and installed blackhole just now. Will report back.

Same issue an a brand new MBP 13" M1.

I even had my MBP swapped for a new one and the new one has the same issue.

Did you route the BlackHole audio to an aggregate device? Or did you pass to another software?

To nothing.. The equivalent of /dev/null

I have this issue too, it's maddening. I also notice when I press "run" on the Touch Bar I get a crackle, every time.

Hey!

Thank you i try it.

I am experiencing the same problem on a MacBook Pro 16" 2019 running 10.15.6 with Xcode 12.0.

The problem occurs when running the simulator or previewing SwiftUI interfaces.

All sound is affected. (Videos, system sounds, video conferences, etc.)

The sound is very crackly making speech almost unintelligible.

Running macOS 10.15.7 and Xcode 12.0.1 seems to have mostly addressed the problem. Out of the last 5 times I have used Xcode, audio was unaffected 4 times. The 1 time it was affected, I was able to quit the simulator and start it again and the audio problem was cured.

Problem seems intermittent. Some days I experience it, some days I don't. I'm running the latest version of Catalina and Xcode.

When the problem occurs, closing Simulator and Xcode and reopening sometimes resolves the problem.

Hi, everybody! There may be a solution you want here. This problem has been bothering me before. Until today, when I tried to test with Airpods Pro, it still made a popping sound, not only that, the sound quality became very poor. It reminds me of the iPhone’s sound quality when it’s screen recording. This inspired me. Maybe we got the wrong idea, not to set the output, but the input. Try to switch between different input device, hope it work. Good luck!!!

So I have had 10 days of use with BlackHole 2ch.

Setting your Simulator Audio output under I/O > Audio output has been working pretty well. Not having the speaker issues..

So if you have this issue, give it a try. The Blackhole installer is referred to in this discussion further up.

I hope Apple are aware of and working on this issue.

Big Sur 11.1

I don't see 11.1 as update. It's 11.0.1, up to date.
