[PATCH 4/4] ALSA: hda - hdmi: Disable ramp-up/down for non-PCM on AMD codecs

2013-10-01 Thread Anssi Hannula
Recent AMD HDMI codecs (revision ID 3 and later, 0x100300 as reported by procfs codec#0) have a configurable ramp-up/down functionality. The documentation ( http://www.x.org/docs/AMD/AMD_HDA_verbs_v2.pdf ) specifies that 180 (meaning 180/256 =~ 0.7) is recommended for PCM and 0 for non-PCM.
