Hello, all;

I've discovered that on the Thinkpad Z13 latpop the builtin speakers don't work. When plugging in headphones through the headphone jack sound is played from the headphones, however no sound has ever been heard from the speakers.

There's already been many complaints leveled against the codecs used by this laptop, namely ALC3306 and ALC287 (the Lenovo spec sheet says the codec used is ALC3306 however alsa displays ALC287).

I'm wondering if there's anything I can do to resolve this issue, and more importantly how can this issue be prevented for other laptops with similar specs.

Below is an output of some relevant commands
