Maybe this is old news but when i browsed through the dmesg output via novacom I found this:
Registering wm8994 device.
wm8994 4-001a: Device registered as type 1
wm8994 4-001a: Audio Codec Device ID: 8994
wm8994 4-001a: revision D
wm8994 4-001a: WM8994 revision D
...and so on
So if only....at least the device should be able to provide HQ audio as well
