The tas2781 smart amp is generally supported as of kernel 6.6... but now
it's a question of if firmware for your laptop is available.

Without your alsa-info, I can't tell if your laptop is supported...

But you can just try the firmware for yourself from here:

Just copy the files into /lib/firmware/ and reboot. Hopefully you have

A number of Lenovo laptops with tas2781 are supported, but I don't think
the list is anywhere near comprehensive so we'll see..?

Good luck!

I'm not sure if these firmware files are yet in the pipeline to be
commonly redistributed at this time... I'll see if there's something I
can do to get that process started.
