Dear brown,

I agree with you, in fact the speaker is indeed doing this way. But
about the hdmi that on the board, I did not find a defination link
snd_soc_dapm_hdmi, so I use snd_soc_dapm_line to replace. The purpose
is to control it link speaker. Or what do you suggest I should do?

Thank you very much.
