The Dell Inspiron Plus 16 has top speakers connected on NID 0x17, which the codec reports as unconnected. These speakers should be connected to the DAC on NID 0x03. --- I don't possess this Laptop myself. The owner of this Laptop reports that the speakers are now active, though there are still problem's.

There are still 2 small issues present:

1. 0,5s delay before the top speakers turn on
2. Popping sound from headphones 5s after the music stops playing

and afterwards when it starts playing again. This can be fixed by disabling power save on the audio driver [...].

I've only written this patch because the issue seemed similar to that on my Lenovo Yoga 9 14IAP7.
