Firmware Test Suite - hda_audio test

HDA audio pin configurations are set by firmware and normally this is sufficient for audio setup (automatic probing). However sometimes the default configuration is not correct and requires a HDA audio quirk to override the defaults. This test compares the default firmware HDA audio configuration against that currently set by the driver. Any differences will indicate that the driver had to work around a broken firmware HDA configuration.

Example output from the test:

Check HDA Audio Pin Configs.
Test 1 of 1: Check HDA Audio Pin Configs.

BIOS pin configurations required software override to make HDA audio work
The driver or user provided overrides should be corrected in BIOS firmware.
