It's not about PCI SSID but the codec SSID.  It's found in the
corresponding /proc/asound/card*/codec#* file.  It might be the same
number as PCI SSID, though.  Please check both Vendor Id and Subsystem
Id lines.

And we need to know those numbers from the conflicting model (Yoga
Diet 7 13ITL6), too.
