From 28009d3918aabba0e0713baa49f8f6367604af51 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 18 Jun 2013 16:14:22 +0200 Subject: [PATCH] ALSA: hda - Cache the MUX selection for generic HDMI commit bddee96b5d0db869f47b195fe48c614ca824203c upstream. When a selection to a converter MUX is changed in hdmi_pcm_open(), it should be cached so that the given connection can be restored properly at PM resume. We need just to replace the corresponding snd_hda_codec_write() call with snd_hda_codec_write_cache().
