The simplest way to stream music from a Raspberry PI <\/strong>to an external amplifier is to connect the headphone jack to the AUX Input of the amplifier with the help of a corresponding connector cable. From a quality point of view a better approach is to use an external Digital to Analog Converter (DAC)\u00a0<\/strong> connected to the I2S pins<\/strong> of the Raspberry PI<\/span> and for a PI Zero<\/strong> this is the only way because it does not have a phone jack.<\/p>\n

Today I received my USD $5.33 I2S DAC from AliExpress<\/a>. I did not expect that this is arriving so quickly: It took less then 2 weeks<\/strong> to have it shipped from China to Switzerland – and this in spite of all the problems with Corona !<\/p>\n

Naturally I wanted to test it and the easiest I figured, might be to connect it to a Raspberry PI<\/strong>. Unfortunately this seems to be quite tricky with Raspian<\/strong>, so I installed the Volumio Music Player Operating System.<\/a><\/strong> In the configuration I just selected the Generic I2S<\/strong> as output.<\/p>\n

I was struggling a bit with the Raspberry PI Pinout<\/strong>:
