From bd25b7cae1e763b292f359170e16bccd01c7ee5c Mon Sep 17 00:00:00 2001 From: Ville Syrjala Date: Mon, 4 Sep 2006 12:28:24 +0200 Subject: [ALSA] ac97: Fix AD1819 volume range AD1819 volume registers can hold extra bits which do not affect the actual volume. Add a res_table to the codec patch to fix the problem. PCM, line and mic volume were tested.
