Just an FYI: that the "Integrated audio" setting (for <= Pi4) in the Audio Config screen that controls whether the Headphone jack is enabled for Audio output does this by switching the between the Firmware (legacy) and Kernel mode video drivers.
Below is the help. Note the limitations when using Firmware mode.
Kernel mode: Default vc4-kms-v3d driver for advanced HDMI capabilities.
Firmware mode: Legacy snd-bcm2835 driver to support Pi Headphone only configuration. No other audio, video or system features are supported.
