Audio HP/Speaker toggle scripts

Audio output control scripts

Simple shell scripts to force audio output to Speaker or Headphone,
useful for boards affected by the bug where both speaker and
headphone play sound at the same time.

Files

• audio-hp.sh — forces audio output to headphone (HP)
• audio-speaker.sh — forces audio output to speaker (SPK)
• audio-toggle.sh — toggles between HP and SPK based on last saved state

Installation

1. Copy the desired script(s) to /roms/tools/

2. (Optional) If the script won't launch, make it executable:
   chmod +x /roms/tools/audio-hp.sh /roms/tools/audio-speaker.sh

3. Launch from the Tools menu in EmulationStation like a regular game/tool.

Notes

• Scripts automatically create /var/local if it doesn't exist yet.
• The chosen output path is saved to /var/local/audio_path, so it can be
  restored on boot/resume (e.g. paired with a custom audio-reinit.sh).
• Tested on board Y3506_V04_20250523 with an aftermarket Panel 5
  (HL-MP35HD-B-V5) display replacement, using dtb Y3506_V05_20251215 (2551).
