No HDMI or speaker sound on Samsung Book2 Pro Ubuntu 22.04

Installed UEFI Ubuntu 22.04 on new Samsung Book2 Pro and HDMI output and speakers do not work. Headphone plugged into jack works. HDMI and sound both work on Win 11. Sound output device indicated as: "Speaker-sof-hda-dsp". Digital Mic indicates input when talking and is also "sof-hda-dsp".

I also modified /etc/default/grub to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=on,igfx_off loglevel=3"

Per this post: HDMI Audio Issue Ubuntu 22.04

Suggestions would be appreciated. Rick
