I can do a dirty fix by either pactl load-module module-detect or pactl load-module module-alsa-sink. In other words, once I run either of them, I got the sink shown from pactl list sinks. Even I do 3, the card profiles are still not available. I don't know if this is a driver problem, but even I manually fix the problem, the sound is sometimes unstable.

Every time I open a sound-related app I hear "bzzz". So my question is why this happens? It seems my hardware and drivers have no problems.
