The speakers in (at least some) Pinebook Pro are out-of-phase. If your audio level seems low, this is probably the cause. I just corrected this on mine, and I strongly encourage everyone to do this. Don't wait for a software band-aid for this hardware problem; that is bad practice.
Of course, you need to remove the bottom of the PBP, and follow all the precautions that normally go with that. Next it's a matter of unplugging the speaker connection from the mainboard. Note the order the wires on the plug are in. Then, mercilessly tear the red and white wires out of the plug. Pull them out by lifting them from the plug, not by pulling in the direction the plug inserts. Swap the positions of the red and white wires, and press them back into the connector with a small flat blade screwdriver. Plug the connector back in. reassemble the PBP, and enjoy better audio.
