I installed the ubuntu hirsute on a Dell machine which enabled sof audio driver and enanbled -proposed ppa, installed the pulseaudio 1:14.2-1ubuntu1.2 and alsa-ucm-conf 1.2.4-2ubuntu1.4. now the speaker and headphone has separate volume from gnome-sound-setting, this verified the pulseaudio's SRU. And adjust the external microphone's volume, the Mic Boost is changed accordingly. This verified the alsa-ucm-conf. And all audio output and input worked as well as before.
