Troubleshooting › Fix: Microphone Not Detected in OpenCode
Symptom: Typing /ptt shows "🎤 Recording..." but transcription returns "⚠️ No audio captured" or sox errors appear in logs.
⚠ sox not installed
→ Install sox: sudo apt install sox (Linux) or brew install sox (macOS).
⚠ Mic permission denied (Linux)
→ Add user to audio group: sudo usermod -a -G audio $USER && exec su -l $USER.
⚠ Mic permission denied (macOS)
→ Grant mic access in System Settings > Privacy & Security > Microphone. Grant it to Terminal/iTerm2.
⚠ Wrong default input device
→ Test with sox -d -t wav - -n stat. Speak — you should see levels. If not, set default input in system audio settings.
⚠ sox fails with device error
→ Try sox --default-device -t wav - or specify the device explicitly with -t alsa plughw:0,0.
Walkie-talkie requires a working mic. For text-only use, the plugin's TTS and text-based interruption still work without mic access.
