New sysfs attributes documented: - sidetone_level: Control microphone monitoring volume - inactive_time: Auto-sleep timeout configuration - chatmix_level: Game/Chat audio balance (read-only) - mic_mute_led_brightness: Microphone mute LED brightness control - mic_volume: Internal microphone gain control - volume_limiter: EU hearing protection volume limiter - bluetooth_on_power: Bluetooth auto-enable on power-on - bluetooth_call_vol: Bluetooth call audio attenuation settings The SRW-S1 LED documentation is preserved and moved into the new unified documentation file.
