HDMI/DP digital audio output is related to iGPU config. Though video output is fine, digital audio only works when connecting both onboard HDMI and DP ports. Connecting only one of them or disconnecting either one will result in the audio device failing to refresh, thus front panel headphone jack will not work. From this discussion

TRIM support for SATA SSD is turned off by default. The performance may be affected. However, some say APFS do not TRIM, since both have garbage collection mechanism. To turn on TRIM
sudo trimforce enable
