From 8c7dd8907637d863bdd175f24e895cbcfe03e1e5 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sat, 12 May 2012 09:38:05 +0200 Subject: [PATCH] ALSA: hda - Disable FLOAT format support It turned out that the FLOAT format on CS4206 results in simple noises, which implies that this is no right format as is. Since CS4206 is the only codec supporting the float, let's disable it until we find the correct format.
