From 4b3acaf5b56f53ef259a6ddf8e17dcb529631d9b Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 10 Jun 2005 19:48:10 +0200 Subject: [PATCH] [ALSA] hda-codec - Feed front signals to all surrounds HDA Codec driver Feed front signals to all surround channels if no data is given for surround channels. It seems that CLFE works as expected (only center outputs) even if connected from the front line - at least on my test system. If this change causes problems on other system (e.g. only the left channel is transferred to the center channel), please let me know...
