# macOS Tahoe Audio Glitch: Diagnosis & Workaround
## Symptom
On macOS Tahoe (26.x, tested on 26.3 / M3 MacBook Air), system audio **gradually degrades** over time — volume drops significantly and sound becomes muffled across **all outputs** (built-in speakers, Bluetooth headphones, etc.) at the same volume setting.
- Onset is intermittent: anywhere from hours to days after a clean reboot.
- `coreaudiod` sometimes shows elevated CPU usage during the degraded state.
- A full reboot reliably restores normal audio. The issue then eventually recurs.

# fixaudio — workaround for macOS Tahoe audio degradation bug
# Kills all CoreAudio clients + all audio daemons to restore normal audio.
#
# Usage: source this file and run `fixaudio`, or add the function to your .zshrc/.bashrc.
# Requires sudo for killing system audio daemons.
