No audio in Ayaneo Air 1s

I've done ujust install sound firmware, rebooted, still no audio. Did I miss something?

Solution

delete the 2 text files and run this

cd /usr/local/firmware
sudo ln -s aw87xxx_acf_minipro.bin aw87xxx_acf_airplus.bin
sudo ln -s aw87xxx_acf_minipro.bin aw87xxx_acf_air1s.bin

cd /usr/local/firmware
sudo ln -s aw87xxx_acf_minipro.bin aw87xxx_acf_airplus.bin
sudo ln -s aw87xxx_acf_minipro.bin aw87xxx_acf_air1s.bin
