The first thing to do is run : lsmod | grep snd_bcm2835ДЄnd check snd_bcm2835 is listed. So I decided to hook up a rechargeable powered speaker I had using a short 3.5mm jack plug lead and see if I could play some WAV and MP3 files.

#PLAY SOUND COMMAND DRIVERS#

One thing that has changed in the latest Raspian image is that the alsa sound drivers have improved and are enabled by default.

IвЂ™m making slow progress with my remote controlled car project but I figured I might as well shoe-horn some audio in there as well. So I decided to take another look as I wanted to start adding some audio to my experiments.

Formulas 1.1.Things have moved on a bit with the Raspbian image since I wrote my Raspberry Pi Speakers & Analog Sound Test post.

In Praat, this key is sometimes used together with the Command key for destructive actions that are the reverse of the actions invoked by using the Command key only.

#PLAY SOUND COMMAND MANUAL#

When mentioning the Option key, this manual refers to the key marked 'alt' or 'option'.

#PLAY SOUND COMMAND WINDOWS#

When mentioning the Command key, this manual refers to the key that is marked with an apple or the word 'command' on Apple keyboards or to the key that is marked 'Ctrl' if you are on a Windows or Linux computer. All of these commands can also be chosen from a menu. To accelerate menu commands in Praat, you can sometimes choose them with the keyboard, sometimes while also pressing the Command key, Option key, or Shift key.
