issue with Virtual box 6.1.3

[Reza-DATA-Engineer]

Hi,

After upgrading VBox from 6.1.26 to 6.1.3 and installing VBox guest client on VM server, Audio driver stop working (input & output). Please see below details, I found from VM log. Also, I was trying to revert it back from 6.1.3 to 6.1.26 along with installing the previous VBox guest client. however, still it does not work. Please share your feedback to solve the issue.
