| Subject: ALSA: hda - Cache the MUX selection for generic HDMI |
| |
| From: Takashi Iwai <tiwai@suse.de> |
| |
| 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(). |
