Bug Description
There is no sound output from the laptop internal speakers when running Ubuntu 20.10.
This is a dual-boot system;
- Booting Windows first and then rebooting to Ubuntu -> sound works fine
- Booting Ubuntu first and then rebooting to Windows -> Windows identifies sound as not enables and runs its troubleshooter to enable it
The card seems to be recognised OK (system sound settings report output device as Speaker - Tiger Lake-LP Smart Sound technology Audio Controller. VU meters etc all appear as if sound is playing, but no sound.
Headphone socket works perfectly.
Similar bug reports for different laptops in the HP x360 series suggest this is a pinning problem and that the extract below from the boot logs may support this.
