I can imagine the backlog (of dedicated devices) is very high but it would be nice to see some laptops with integrated audio codecs tested here (dac + HP power test). As I am a long time Lenovo/Thinkpad fan, I've compiled this short list of chips they use. I'd suggest to test some model with Realtek ALC3287, as it is most widely incorporated in recent mainstream/mid models. ALC3306 is another candidate, used in higher end models.
It's been a while we have had some laptop reviewed here (only one until this day I think).
