[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... Signed-off-by: Takashi Iwai <tiwai@suse.de>
