This HP All-in-One desktop (model 27-ca1xxx) uses an ALC274 codec and has no sound from either the internal speakers or the headphone jack. The audio output requires a combination of a specific verb setup and GPIO configuration to become functional. Additionally, the power_save feature must be disabled; otherwise, audible clicks or pops occur during power state transitions.
