Speaker

largely inspired by https://github.com/maximmaxim345/yoga_pro_9i_gen9_linux , but I only had the right side working

This little script find the address of sound card .


for addr in $(seq 3 119); do
  hexaddr=$(printf "0x%02x" $addr)
  echo -n "Probing $hexaddr... "
  sudo i2cget -y 17 $hexaddr 0x00 b 2>/dev/null && echo "Found!" || echo "Nope"
done

0x38 and 0x3e , address are the same of maxim345 code

sudo pacman -Sy i2c-tools

then simplify

#!/bin/bash

i2c_bus=17
amp_addresses=(0x38 0x3e)

for i2c_addr in "${amp_addresses[@]}"; do
 echo "Configuring amp at address $i2c_addr on i2c-$i2c_bus"

and now the sound work perfectly 🙂

create a service :

sudo nano /etc/systemd/system/yoga-16imh9-speakers.service

sudo systemctl daemon-reload

Si on veut savoir dans les logs si le son était « faible » ou « normal », il faut :

Logger un message clair : « SON FAIBLE détecté » ou « Son normal »
