Raspberry Pi and audio

first make sure your audio is going to where you want it to (i.e. not going through your HDMI cord to a screen that has no speaker).
- ```
sudo raspi-config
```
- Advanced Options
- Audio
- choose the output you want
Next test the output by typing
- ```
aplay /usr/share/sounds/alsa/*
```
- You should hear files being play as they appear in the terminal.
if still having problems
- make sure the speaker is plugged in
- make sure the speaker is on
- consult the raspberry pi documentation https://www.raspberrypi.org/documentation/configuration/audio-config.md
For text to speak on the Raspberry Pi, install espeak
- ```
sudo apt-get install espeak
```
Test it installed correctly with:
- ```
espeak "Text you wish to hear back" 2>/dev/null
```
- also can write:
```
echo "Text to speak" | espeak2 >/dev/null
```
- The “2>/dev/null” gets rid of the clutter. check out this for more explanation. https://askubuntu.com/questions/350208/what-does-2-dev-null-mean
To modify the voice of espeak try:
- ```
espeak -vfr "Bonjour" 2>/dev/null
```
- ```
espeak -ven+f4 "Hello World" 2>/dev/null
```
- for more options check out this tutorial: https://www.dexterindustries.com/howto/make-your-raspberry-pi-speak/
To use espeak with python type
- ```
sudo apt-get install python-espeak
```
  - To download both espeak and python-espeak at the same time type:
```
sudo apt-get install espeak python-espeak
```
