Initialize audio_comp when audio starts and wait for audio_comp at
dp_display_disable(). This will take care of both dongle unplugged

Changes in v2:
-- add dp_display_start_audio()

This doesn't need to be done early anymore? Please mention why in the
commit text.
This is my mistake, it still need signal audio here, will fix it
