It's not that hda-intel cannot detect the sub-model but that
many BIOSes incorrectly initialise their codecs, hence the
foo_cfg_tbl quirk entries.

It is my understanding that ALSA issues, like the ones you describe above,
originate mostly from one single driver, the driver for Intel HDA cards. Is it
the fact that the driver has difficulty detecting the audio card's
sub-model(sub-models are the vendor specific versions of these audio cards that
have changes made to them by the OEM) that many of these issues happen. The way
the driver is designed is that it uses the BIOS to automaticly detect the
sub-model, but many OEMs do not specify the sub-model in the BIOS like they
should.
Perhaps there is some other method this driver can use to try to detect the
Intel card's sub-model?
