I tried to register an unsollicited event with CORB_SET_UNSOLICITED_RESPONSE
with a COP_AWCAP_UNSOL_CAPABLE headphone pin, checking it was set
with CORB_GET_UNSOLICITED_RESPONSE, but then in hdafg_unsol, when I
plugged in the headphone, the event was tagged with a different number,
making it tricky to say "the head phones have been plugged in, swap
streams".
