The problem is that SOF tries to do reverse-select the legacy HD-audio codec, but it doesn't work in general. Or it must be done very carefully.
If something gets selected, all dependencies have to be reverse-selected, too. But the legacy HDA is built up in a way of standard top-down selection (i.e. SND_HDA_CODEC_* depends on SND_HDA, not other way round).
