So I want to ask if I can do it by just adding SOC_DAPM_PIN_SWITCH("Speakers") and SOC_DAPM_PIN_SWITCH("HDMI")? Correspondingly, dapm widget and route path need to be added. That is "SND_SOC_DAPM_SPK("Speakers", NULL)/ SND_SOC_DAPM_LINE("HDMI1", NULL)" and "{"Speakers", NULL, "Speaker"}/ {"HDMI1", NULL, "TX"}".
Yes, that's what I'd expect to see.
So if I open the "HDMI Switch" amixer control, it will call 'hdmi_codec_startup', which in turn calls "audio_startup()" in 'hdmi_codec_ops'. Conversely, if I close it, it will call 'hdmi_codec_shutdown', which in turn calls 'audio_shutdown' in 'hdmi_codec_ops'. Is this understanding correct?
The audio stream will still run, the DAPM path attached to it will get shut down.
