GPIO #18 is also known as PWM0 and in the original Pi was coupled with a very basic RC filter to create the audio output: If you don't mind getting a few 150 and 270 ohm resistors, and two each of about 33nF (also known as 0.033uF) and 10uF capacitors, you can basically recreate those two filters. Now all you need is access to PWM0_OUT and PWM1_OUT, …

Therefore, to force the Raspberry Pi to use the analog output: amixer cset numid=3 1. Sound Check. With this done, you should be ready for a simple test. Plug a speaker into the (RPi) Audio Output 3.5mm jack. I used a simple battery powered iHM60 iHome speaker. The jack will not deliver much power, so the speaker needs to be powered.

Audio Output. Audio output on the Raspberry Pi is done through either the HDMI connector or the 1/8" blue headphone connector. Control of which connector the audio is present on is done through the amixer command. amixer is one of a suite of the ALSA control tools. ALSA is the Advanced Linux Sound Architecture and provides a set of utilities to configure and control …

Audio is 20Hz to 20KHz, and the PWM output from the Pi is 50MHz so we can easily filter the high 50MHz out (and anyways it cant be heard). Looking at the Pi B schematic, we can see PWM0_OUT and PWM1_OUT are the left and right channels. R21 and R20 are voltage dividers to get the 3.3V signal down to
