# Audio section

<abstract>
The CM-Home uses an audio section electrically similar to the Raspberry Pi 4 but using 
different GPIO lines. This article explains how to configure your Raspbian distribution to
be compatible with this hardware. Making a little change on the config.txt file all the other 
behaviour is the same as with Raspberry Pi 4.
