🎧 Headphone jack stops working after sleep on MacBook Air M4 (macOS Sequoia)
I have a recurring issue with my new MacBook Air M4.
After waking up from sleep mode, the 3.5 mm headset (AUX) is no longer detected — it completely disappears from the sound output list in System Settings → Sound → Output.
Physically unplugging and reconnecting the headset doesn’t help.
The only workaround so far is to restart the Mac, after which the headset is recognized again and works normally — until the next sleep/wake cycle.
I’ve already:
- Cleaned the audio jack
- Checked Sound preferences
- Installed all latest macOS updates
Nothing fixed it so far.
Seems like a software bug affecting the audio driver or sleep/wake handling on the M4 chip.
Has anyone found a reliable workaround or fix for this issue?
