Lenovo 13s Gen2 sound problems
I'm not new to ubuntu but it has been a long time since I installed it on a new laptop and had to troubleshoot problems so i may as well be new.
Laptop = Lenovo 13s Gen 2
Ubuntu 20.04.2 LTS
Issue = Sounds plays fine on Windows. On ubuntu there is no sound from the internal speakers. If I plug in wired headphone it just gives a screeching sound whether or not sound is playing. If I use HDMI to connect to a tv the sound plays just fine. If I connect to bluetooth headphones the sound plays just fine.

seems to indicate codec is Realtek ALC287. If i read this bug report

right it seems I'm out of luck and there is no solution at this time?
Although on

Any insights into how I may be able to get wired headphones or the internal speakers to play would be appreciated.
