It's not a subsystem issue, it's an issue with the half baked support for enumerating modern audio hardware on ACPI systems. Unfortunately we have to enumerate hardware based on having data tables instantiated via DMI information for the system which doesn't work well with a generic kernel like Linux, on Windows they're per-machine custom drivers. There is some effort at putting some of the data into ACPI tables on newer systems which is helping a lot but it's partial.
