From 4f34760787c3751a3146f0eecdc79c3e97b94962 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 20 Aug 2010 09:41:59 +0200 Subject: [PATCH] ALSA: hda - Fix conflict of sticky PCM parameter in HDMI codecs Intel and Nvidia HDMI codec drivers have own implementations of sticky PCM parameters. Now HD-audio core part already has it, thus both setups conflict. The fix is simply remove the part in patch_intelhdmi.c and patch_nvhdmi.c and simply call snd_hda_codec_setup_stream() as usual.
