I have installed RuneAudio v0.3-beta on my Raspberry Pi 2B plus Digi+ sound card.
In the audio output menu the Digi+ option is missing however.
I can only choose analog or HDMI output.
I'm I doing something wrong?

You need to enable I2S in Settings before the option becomes available for selection.

Hi,

you have to edit the file /boot/config.txt see here.

This is correct for the older PIs, but not for Pi 2B.
On a Pi2 there is a help text on the settings page:

Enable I2S output by selecting one of the available sets of modules (in this version you have to edit /boot/config.txt), specific for each hardware. Once set, the output interface will appear in the MPD configuration select menu, and modules will also auto-load from the next reboot.

Thnx, looks like I missed the small print.

I do not understand what this is telling me to do. Anyone willing to lay it out for this newbie? Thanks.

Hi pzwief,

From here:

As it's an embedded platform, the Raspberry Pi doesn't have a BIOS like you'd find on a conventional PC. The various system configuration parameters, which would traditionally be edited and stored using a BIOS, are stored in an optional text file named config.txt. This is read by the GPU before the ARM CPU (and Linux) is initialised; therefore it must be located on the first (boot) partition of your SD card, alongside bootcode.bin and start.elf. This file is normally accessible as /boot/config.txt from Linux and must be edited as root; but from Windows or OS X it is seen as a file in the only accessible part of the card. If you need to apply some of the config settings below, but you don't have a config.txt on your boot partition yet, then simply create it as a new text file.

Any changes will only take effect after you've rebooted your Raspberry Pi.

Put your sd card into your PC or Mac and navigate to the folder /boot.
Now you have to edit the file "config.txt".

Code: Select all: # Uncomment one of these lines to enable an audio interface #device_tree_overlay=hifiberry-dac #device_tree_overlay=hifiberry-dacplus #device_tree_overlay=hifiberry-digi #device_tree_overlay=hifiberry-amp #device_tree_overlay=iqaudio-dac #device_tree_overlay=iqaudio-dacplus

For the HifiBerry Digi+ it should look like this:

Code: Select all: # Uncomment one of these lines to enable an audio interface #device_tree_overlay=hifiberry-dac #device_tree_overlay=hifiberry-dacplus device_tree_overlay=hifiberry-digi #device_tree_overlay=hifiberry-amp #device_tree_overlay=iqaudio-dac #device_tree_overlay=iqaudio-dacplus

Put the card back in your Pi and power it up.
Now you should be able to select the HifiBerry Digi+ under MENU->Mpd
