==== Stupefying OpenWRT Configuration ==== | |||
''Burying the Lede'': remove --disallow-module-loading from the command line start parameter for PulseAudio in /etc/inid.d/pulseaudio | |||
The default configuration in the /etc/init.d/pulseaudio 'start script' makes it impossible for the 'BlueZ' software to add BlueTooth Speakers. Why? Not a clue. Wait! Let's ask ChatGPT;<syntaxhighlight lang="text"> | |||
What would the effect / affect be on BlueTooth Audio if PulseAudio's init.d startup script had this directive?: --disallow-module-loading | |||
Speculate why that would be added to PulseAudio's init.d startup script and explain what would happen to a system's ability to play audio through BlueTooth Speakers. | |||
Effect on Bluetooth Audio: | |||
The --disallow-module-loading flag can have significant consequences on Bluetooth audio, as PulseAudio often dynamically loads modules related to Bluetooth support during runtime. For example, PulseAudio uses the module-bluetooth-discover to handle Bluetooth devices like A2DP sinks (for streaming audio) and HSP/HFP (for hands-free profiles). | |||
If --disallow-module-loading is enabled, PulseAudio will not be able to load any Bluetooth-related modules, effectively disabling Bluetooth audio functionality. This means: | |||
Bluetooth devices (headphones, speakers, etc.) that rely on PulseAudio to manage A2DP or HSP profiles would not be usable. | |||
If someone tries to manually load a Bluetooth module after PulseAudio has started (e.g., using pactl load-module), it will fail because dynamic module loading is disabled. | |||
Speculation on Why Someone Would Use This for Bluetooth: | |||
System Configuration Control: In some specialized environments (e.g., headless systems, embedded devices, or systems that should not handle Bluetooth audio), disabling Bluetooth audio might be a desired action. By using --disallow-module-loading, you ensure that no Bluetooth modules are loaded at startup or after startup. | |||
Prevent Unwanted Audio Connections: In environments where only certain audio outputs are allowed (e.g., using a dedicated audio interface or a fixed set of speakers), disallowing module loading might prevent accidental or unwanted use of Bluetooth audio devices. | |||
Security Reasons: As mentioned, controlling what modules can be loaded might be part of a security strategy to prevent rogue or insecure Bluetooth devices from being accessed via PulseAudio. | |||
</syntaxhighlight>The OpenWRT developer that made that decision is insane. It is equivalent to unplugging a network cable to keep a server secure. Yes it is secure, but also useless. See the insanity of it? | |||
Solution: remove --disallow-module-loading from /etc/inid.d/pulseaudio | |||
