Many thanks for your prompt response. If I remove, "options snd-intel- dspcfg dsp_driver=1" from /etc/modprobe.d/alsa-base.conf, then on pavucontrol, I see "Dummy Output" on the "Output Devices" tab and the speakers will not work. Attaching alsa-info here:

I only have "Dummy output" in pavucontrol. To fix this, I modified /etc/modprobe.d/alsa- base.conf and added "options snd-intel-dspcfg dsp_driver=1" so that now "snd-hda-intel" is loaded instead of sof-audio-pci. While the speakers are working fine, I do not have the internal microphone working (suspect a digital array).
