Lenovo miix 3 1030, running dualboot win10 and lubuntu 20.04, can't get sound to work, it's recognized as bytcr-rt5640, i've tried downloading ucm files and blasklisted hdmi audio, but it didn't help.
Here are some commands i ran https://pastebin.com/Lp6UcNrY , in pavucontrol i have "speakers" and "headphones(unplugged)" and when i try to switch to headphones it says "establishing connection to pulseaudio please wait" then window is realoaded and it's switched to speakers again.
Also i should mention that this device has only one speaker, when other tablets with same sound, like acer aspire switch 10 or asus t100 have 2.
