Hi, first of all i want to say thanks for your work.
I got the beelink mxiii ii mini 905x. I tried to upgrade to newer versions from 8.0.1l. In 8.0.1l everything works fine. In the newer versions i got no sound. Also im running in errors installing dependencies when trying to install addons. Tested serveral Versions of 8.0.2 and 8.1.x without success, all of them show the same behaviour.
Went back to 8.0.1l and everything works fine again.
I did no update, just clean install with new dtb placed on the sd.
forgott to say: i also got problems getting connected to some online sources through file manager, in 8.0.1l there is no problem.
