[ALSA] hda-codec - Avoid overload of PCM volume on Cx5045 codec
The PCM volume of Cx5045 codec has overload that isn't useful but rather harmful. Add a hack to override the amp info to set the max level 0 dB. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
