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

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