Hi Friends,
In previous post I write about the problem with wolfson pi which is later on resolved.
So I forgot to mention about how to use wolfson pi with raspberry pi.
In real using wolfson pi is simple just to execute a script to select the playback and recording device.
The script is placed in home folder in use_case_scripts folder.
Simply execute those scripts to select your choice of playback and recording device. Or you can just enter the following in terminal to execute the script to select your choice of recording or playback device. First go to the use_case_scripts folder in terminal using
$ cd ~/use_case_scripts
Then enter from the following to select playback and recording device.
Command in Terminal | Function |
./Playback_to_Headset.sh | Play an audio files to your headphones |
./Playback_to_Lineout.sh | Play an audio file to the line out jack |
./Playback_to_Speakers.sh | Play an audio files to loudspeakers |
./SPDIF_playback.sh | Play an audio files to the SPDIF output |
./Record_from_DMIC.sh | Record from onboard digital microphones |
./Record_from_Headset.sh | Record from the boom microphones |
./Record_from_lineIn.sh | Record from the analogue Line in socket |
./SPDIF_record.sh | Record from the SPDIF input |
./Reset_paths.sh | Reset all audio paths |
Simply enter one of these commands in terminal to select the playback and recording device.
You will also need some of the other software in order to play the Hi-Def audio files. I installed these packages using
$ sudo apt-get install lxmusic xmms2 xmms2-plugin-all volumeicon-alsa mpg123 mplayer
These will install the important packages that you’ll need to play Hi-Def audio.
Other than this I installed the VLC player in my raspberry pi.
I installed the VLC player in terminal using
$ sudo apt-get install vlc browser-plugin-vlc
See my VLC player in action

You can also use your basic audio output of raspberry pi which is bcm2835 in VLC player.
Just go to Tool-> Preferences -> and select your bcm2835 as output device. As shown in image.

This will select your base audio output of raspberry as playback device for VLC player. You can switch back to wolfson or if you have connect USB sound card you can select that too as output device.
This is what I have done till now.
