Hey Apple,
I'm experiencing cracking speaker sound when simulator is launched and running on my Xcode project. The fans will go high and after a while cracking sound will gone, but when I change my codes and build/preview Swift UI, the jet fans go high again and speakers sound is cracking again.
Please help. I have reset my PRAM and still having the same issue.
MacBook Pro
I think there is a way to solve this in the quickest way: killing the simulator and audio process from the terminal
```
xcrun simctl shutdown all
```
and
```
sudo killall coreaudiod
```
Still a workaround but at least I don't need to restart my mac.
I don't see 11.1 as update. It's 11.0.1, up to date.
My apologies, I forgot to mention. It's the Big Sur 11.1 public beta.
Hi. This is my fix:
Go to Sound Preferences -> Input -> completely reduce the microphone Input volume.
Running on MacBook Pro 2020 13' Quad-core i5 with 16GB 3733 MHz RAM. Catalina 10.15.5 with Xcode 12.0.
I have the same version as you and I have this issue when I open the simulator.
I just got my MacBook Pro 16’’ 3 days ago
me too, but I try to open it again, the sound will return to normal, hopefully it will return to normal when the version is released
Same here, super annoying.
Brand new MBP 16" / 32 GB RAM / 1 TB SSD / i9 CPU / macOS 10.15.7 / Xcode 12.1
This problem literally makes developing SwiftUI projects impossible because of Live Preview.
WHAT THE **** IS GOING ON APPLE? I'm facing this issue too....I just purchased my MacBook Pro 2020 13" 5 hours ago!!!!
HOW CAN I EXPECT AN EXPERIENCE LIKE THIS WITHIN 5 HOURS? What's going on?
Same issue here
MacBook Pro (15-inch, 2019)
2,4 GHz 8-Core Intel Core i9
32 GB 2400 MHz DDR4
XCode Version 12.2 (12B45b)
I'm having the same issue when in SwiftUI. I'm currently running the latest version of MacOS and Xcode on MacBook Pro (16-inch, 2019).
I tried that but I still doesn't fix it unless I'm doing something wrong. 🤷🏻♂️ But I ran the Simulator and then changed the IO from the system one but still does the same. Thank you though!
I hope Apple are aware of and working on this issue.
My solutions was go to simulator open I/O menu -> Audio Output -> MacBook speakers, if you are using headphones (use different audio output)
Mine seems to be working now after the last update.
