I guess v3 kernel will work successfully, after boot up, you could run alsa -l to check if there is valid sound card.
and pulseaudio will have an error on your machine, so if the kernel has no error, please backup /usr/share/alsa/ucm2/sof-hda-dsp/Hdmi.conf, and I uploaded a new Hdmi.conf in https://people.canonical.com/~hwang4/25skipi915/v3/, please copy this file /usr/share/alsa/ucm2/sof-hda-dsp/
Please test v3 kernel: https:/ /people. canonical. com/~hwang4/ 25skipi915/ v3/
