This chip does not support sample rates larger then 48kHz. It is cheap, but features the Burr Brown PCM2902 audio chip which provides a good audio quality. Therefore an additional sound card is needed. Unfortunately the Raspberry Pi does not feature a analog or digital sound input. It could also be a media server that broadcasts music stored on an attached hard disk. Every receiver just listens to the RTP stream that it is interested in:Īudio source must not be a sound card with a line input. Think about different audio source that can be distributed to different receivers. The simplest setup is a point-to-point setup with one sender (the Raspberry Pi with a sound card as line input) and a receiver on the other side (this could be another Raspberry Pi, a PC or a RTP enabled streaming client).īut there are much more interesting (and complex) setups possible. Interested in a add-on sound board? Check out our Raspberry Pi DAC project HifiBerry Mini .ĭo you want to control the volume of external sound sources with your Raspberry Pi? Check out our Quad Volume Control circuit, that is Raspberry compatible! Schematic setup You should use the HDMI audio output or an external sound card. Note that the audio quality of the internal “sound card” of the Raspberry Pi is very unsatisfactory. That means the utilization of a 100Mbit/s LAN is less than 2%. Using uncompressed audio a stereo audio transmission uses about 180kByte/s on your LAN. This can be used for audio distribution in your house. It broadcasts music from the Line input of the sound card to your local network.

Take it as a guideline and adapt it wherever necessary. Since this time, the software used in this project has changed a lot. Note: This guide has been written in 2011.
