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
$ aplay -l
