I could be wrong, but this looks to me like your system needs to fallback to a different module due to the one you are trying to use being on the blacklist (or denylist).
This probably relates. Had you done any troubleshooting on your sound issue where you checked the contents of /etc/modprobe.d/blacklist.conf
or other contents of /etc/modprobe.d?
Had you used modprobe to try troubleshooting your issue initially?

Then check with the cat command, again (You should be able to up arrow key in your terminal to retrieve it from history, then just hit enter to act on it.
There is a file in the same directory called power_save_controller with "Y".
Perhaps this one is of influence on the power_save file, just thinking along.
