# AUDIO

## PURE ALSA

Here is how to get sound on a minimal install without the insanity of pulseaudio:

1. Erase .asoundrc in your home directory and asound.conf in /etc.  

2. Purge pulseaudio. And when I mean purge, I mean it.  

3. Identify your available devices in /proc/asound/modules, do:  
`$ cat /proc/asound/modules`

Here is an exampl of /proc/asound/modules:  
`0 snd_usb_audio`  
`1 snd_hda_intel`  

4. Select from the above and put them in the order you want in the file /etc/modprobe.d/alsa-base.conf, by assigning an index from -2 to 2, making the preferred output the lowest number. As I know I have two devices I want the one that says usb because that is my headphone, so in /etc/modprobe.d/alsa-base.conf I put:  
`options snd_usb_audio enable=1 index=0`  
`options snd_hda_intel index=1`  

Notice the index.  

5. Restart the computer.  

6. To run Firefox without pulseaudio install apulse.  

7. Go to about:config and enter "__/dev/snd/__" under __security.sandbox.content.read_path_whitelist__ and __security.sandbox.content.write_path_whitelist;/dev/snd/__.  

8. Every time you want to use firefox with this setting issue the command:  
`$ apulse firefox`  

8. Save it in a script or .desktop file to automate this.
