Fix: sox Errors in OpenCode Interrupt

⚠ sox not installed

→ Install sox: sudo apt install sox (Ubuntu), brew install sox (macOS), sudo pacman -S sox (Arch).

⚠ sox cannot open audio device

→ Test: sox -d -t wav /dev/null. If it fails, check that no other process has exclusive access to the mic. Close other audio apps.

⚠ Permission denied (Linux)

→ Add user to audio group: sudo usermod -a -G audio $USER. Log out and back in for the change to take effect.

⚠ ALSA vs PulseAudio conflict

→ If sox tries to use ALSA directly while PulseAudio is running, set the device: export SOX_DEVICE="pulse".

⚠ sox binary mismatch

→ Some distros package "sox" but the binary is named "rec" or "play". Verify: which sox or which rec.
