Short answer: virtually any HDA codec is supported and there are good chances that sound will just work on this laptop. Long answer: The HDA spec. allows the driver (i.e. azalia(4)) to control all HDA-compatible codecs in a uniform way, so any past or future codec is supposed to just work with the current driver, provided the codec is HDA compatible. There are rare hardware bugs or "creative" ways of connecting the codec to the HDA host that cause problems, most of them are handled by quirks in the azalia(4) driver. There are few laptops that have HDA codecs that require firmware to make advanced features work. Certain recent laptops come with microphones that are not physically connected to the HDA codec (instead they use a secondary audio device OpenBSD doesn't support yet).
