Changing the /boot/config.txt to Add a Soundcard Driver
If you have an own soundcard for your Raspberry Pi or do want to have the kernel configuration of your FMB, please follow these steps
- Remove the microSD card from the FMB.
- Insert it into your PC
- A drive called “boot” should appear now. Open it with your file viewer.
- You should see now a file called “config.txt”. Do not change it. Instead, make the modification in the file “config.local.txt”. For example, you may add lines such as
dtoverlay=hifiberry-dacplusadcpro # dtoverlay=hifiberry-digi # dtoverlay=hifiberry-dacplusadc # dtoverlay=fe-pi-audio lcd_rotate=2
- Eject the microSD and insert it into the FMB. Now, reboot, wait for 3 minutes, and reboot again. Then, the settings are active.
