I'm having audio glitches even under the device is underload a little bit just a little bit and I don't know how to fix that thing. It happens just after the macOs Tahoe update. I didn't have any problems in previous Os.

Original Title: Audio Glitches
MacBook Air 13″, macOS 26.0
I did not notice this response when browsing the thread initially. I too had Xcode Developer Tools iPhone/iOS Simulator app open and yes it clearly causes/amplifies the problem. Closing iOS Simulator removed all audio glitches! My guess it's not just iOS Simulator but simultaneous open active apps interfacing with macOS audio services do not play well together in current Tahoe system. Maybe.
I'm not sure if there was an update yesterday, but today, when I used my MacBook, the sound problem was resolved.
This is false :( Issue still there..
Hey bro thanks my right speaker is working

As of Tahoe 26.2 on my machine mini with M1 chip it is NOT fixed
Adding my upvote to fix this issue as soon as possible. The `sudo killall coreaudiod` only works for a few seconds in my case. I'm not going to constantly reset this daemon. I might as well switch to another device in that case.
I'm only trying to listen to Apple Music. This is not third party software and shouldn't be difficult for Apple to fix as it controls both the OS and the application.
Subject: Right Speaker Crackles / Stops Working After Sleep or Restart – macOS Tahoe 26 (MacBook Pro 14” M1 Pro 2021)
Description:
After updating my MacBook Pro (14‑inch, M1 Pro, 2021) to macOS Tahoe 26, I’ve encountered a recurring audio issue affecting the right internal speaker. After waking from sleep or restarting, the right speaker starts crackling (“zzz / krrrr”) and often stops producing sound entirely.
If I keep the Mac awake continuously, both speakers work perfectly — so this seems tied to power management or the CoreAudio driver, rather than a hardware defect. Both left and right channels appear in System Information, showing the device is still recognized correctly.
Temporary workarounds tried:
Despite all these steps, the issue persists consistently after every restart or sleep–wake cycle.
Impact:
The right speaker becomes unusable until I manually restart CoreAudio or reboot several times. This severely affects media playback and everyday usage.
Request:
Please investigate this potential macOS Tahoe 26 audio driver or power management bug on M1 Pro models, as multiple users are reporting the same symptoms online. Any acknowledgment or fix in an upcoming update would be greatly appreciated.
System:
Thank you for your attention and support.
Same here on v26.0.0 and on 26.0.1. It goes on for weeks now! v26.0.1 update helped nothing!!
(BTW the machine is casually getting hot, which has never happened before.)
Some of my colleagues have this issue as well.
This fix works, but only for a short period of time:
sudo pkill coreaudiod

This was the solution for me, I had a simulator running without realizing it. After removing it, I haven't experiences any sound issue anymore!
