Title:
PCI/internal sound card not detected. Lenovo X1 Carbon Gen 7 Comet
Lake
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
It looks like 20.04 is now using sound open firmware (sof), however, sof does
not have a driver(?) for Intel Comet Lake processors (which my Lenovo X1 Carbon
Gen 7 laptop has). Here is the relevant output of dmesg:
