You're welcome. I'm going to mark the bug Invalid since it appears the kernel module got borked (probably as a result of you "trying several threads and guides"), which makes diagnosing the original issue impossible. If you encounter the issue again, please file a new bug (with ALSA info) before trying to fix it. Enjoy your sound!
