Hello! I recently install recent version of windows on separate partition and got garbaged sound on booth OS! My old version of windows was 1803 and everying was ok, I updated to 1909 and it got broken sound. Probably due to some firmware / configs / updates on sound chip. I let Windows to update drivers and notice my sound card driver got replaced by realtek drivers and sound got fixed on windows! But linux still not working propertly! I put more details with alsa-info output to the ubuntu bug reporter, for now: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1876459 -- AK
