“Audio volume is very low.”

Well, it is low because the speaker hardware is set to low levels in the mixer.
You can just “fix” that by increasing it:

  1. Run “alsamixer”.
  2. Select sound card - choose the second sound card SC8280XP-LENOVO-X13S (despite the first sound card control works, the amplifier is in the second sound card).
  3. Keep moving to the right until you can see “SpkrRight PA Volume” and “SpkrLeft PA Volume”, set them to like 80…90.
