Title:
audio card not detected after upgrade to 20.04 (Only Dummy Output
appears)
Status in alsa-driver package in Ubuntu:
New
Bug description:
Since upgrading to 20.04 the sound card is no longer detected.
This means that I can only see "Dummy Output" in the sound settings.
The audio works if I use Bluetooth headphones but not if I try to use
the speakers or the 3.5mm headphone jack.
My machine is a Lenovo ThinkPad X1 Yoga (4th gen).
