Linux 5.14 Picks Up Support For New Sound Hardware, Including Alder Lake M

Linux 5.14 is ready to begin supporting some new sound hardware while some recently proposed USB audio latency improvements were rejected for now. The sound subsystem updates were sent in on Friday. As written about last month there has been work on lowering the latency for the USB audio driver. While sent in as part of Friday's merge request, Linus Torvalds ended up rejecting that change. After pulling the changes he was getting a hang on one of his systems. There is already a possible fix pending so we'll see if the USB latency audio reduction work is re-sent in next week for Linux 5.14 or held off until 5.15.
