Thanks.

The alsa-info.sh output for the Yoga Duet 7 is here:

http://alsa-project.org/db/?f=5500aa1b489d2ef4ee6ac3ee613f11f3ed8ecfa8

This confirms that the codec is different, so I've asked
@nikitashvets to test the below patch you suggested and
he has confirmed that this fixes things (thank you @nikitashvets).

Takashi, if you can turn this into a proper patch (-series?)
and merge it that would be great!

Regards,

Hans
