Re: debian on apple powerbook

Hi Giuseppe!

Battery:
If the battery status is not displayed correctly then open up the 
terminal and type:
sudo modprobe pmu_battery

To make this permanent type the following:
sudo nano /etc/modules

Add the line

pmu_battery

sound:
To get sound working install alsa-utils and launch alsamixer

sudo apt install alsa-utils
alsamixer

Then hit fn+F6 (SoundByLayout)
go to the right and make sure you have PCM at 80<>80
ESC to exit alsamixer

You should have sound now…

Regards,
Jeroen
