Recently Intel added a new audio driver in the Linux kernel, it is called sof driver. This driver is needed on the laptops which connects the digital mic to the PCH instead of the codec. To make the sof driver work with pulseaudio, the ucm is mandatory. With the ucm, the multi-function audio jack has different port names in the pulseaudio from the one without ucm, these are the port names with the ucm: [In] Mic1: Digital Microphone [In] Mic2: Headphones Stereo Microphone [In] Headset: Headset Mono Microphone [Out] Headphones: Headphones [Out] Speaker: Speaker To make the audio device selection work on the machines using the ucm, the pulseaudio introduces a change to add 2 new members in the device port structure from the PA_PROTOCOL_VERSION=34, with these 2 members' help, we could consolidate the port finding and setting for both with ucm and without ucm. And this patch maintains the backward compatibility with the PA_PROTOCOL_VERSION < 34.
