+Subject: [PATCH] ALSA: hda/realek: extend quirks for Clevo V5[46]0
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+The mic in those laptops suffers too high gain resulting in mostly (fan
+or else) noise being recorded. In addition to the existing fixup about
+mic detection, apply also limiting its boost. While at it, extend the
+quirk to also V5[46]0TNE models, which have the same issue.
