I gave a Raspberry Pi Zero W a Bluetooth soundbar to drive

I've had a Raspberry Pi Zero W sitting under my soundbar for about a year. The job description was simple: be the one device on the soundbar's Bluetooth allowlist so I never have to repair anything, and play whatever audio my MacBook shoves at it. That's it. No screen, no DAC, no hat. Just a tiny board acting as a permanent Bluetooth client.
