ALSA: hda - Turn on PIN_OUT from hdmi playback prepare.
commit 9e76e6d031482194a5b24d8e9ab88063fbd6b4b5 upstream. Turn on the pin widget's PIN_OUT bit from playback prepare. The pin is enabled in open, but is disabled in hdmi_init_pin which is called during system resume. This causes a system suspend/resume during playback to mute HDMI/DP. Enabling the pin in prepare instead of open allows calling snd_pcm_prepare after a system resume to restore audio.
