I have a Lenovo Ideapad 330-151KB, and on fresh install the laptop's internal speakers weren't working but the headphone jack was working. My goal is to have both working and also have the laptop speakers turn off when headphones are plugged in.
Here's what I've done so far:
I was able to get the speakers working by adding a hint for nid20 in /boot/device.hints, but now the headphones don't work. I also added a hint for the headphones, putting them and the speakers in the same association with the Headphones having a sequence 15 and Speaker sequence 0, as this was recommended by shepper in another post here to get the speakers to cancel out when headphones are plugged in.
When the headphones were working (on fresh install), they were originally as=1 seq=0, and the Speaker (not working) was originally as=2 seq=0.
Thanks in advance for help getting the headphones working and having them cancel out the speaker when plugged in.
Here's the pertinent output / configs:

Code:

hint.hdaa.0.nid33.config="as=1 seq=15 device=Headphones"When the headphones were working (on fresh install), they were originally as=1 seq=0, and the Speaker (not working) was originally as=2 seq=0.
