# 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 example of what you will see in __/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, marking the preferred device as the lowest number.
As an example if you have two devices and want the one that says usb because that is your headphone, on __/etc/modprobe.d/alsa-base.conf__ you will put:
```
options snd_usb_audio enable=1 index=0
options snd_hda_intel index=1
```
Notice the index.
5. Restart the computer.
### Run Firefox without pulseaudio
1. Install __[apulse](https://github.com/i-rinat/apulse)__.
* Install _"cmake"_, _"libasound2-dev"_ and _"libglib2.0-dev"_ with your package manager.
* Download _"apulse"_:
`git clone --depth 1 --single-branch https://github.com/i-rinat/apulse.git`
* Change to that directory:
`cd apulse/src`
* Build:
```
$ cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release ..
$ make
# sudo make install
```
2. On Firefox open __about:config__ and enter "__/dev/snd/__" under __security.sandbox.content.read_path_whitelist__ and __security.sandbox.content.write_path_whitelist;/dev/snd/__, IF they exist.
3. Every time you want to use firefox with this setting issue the command:
`$ apulse firefox`
Alternatively save _"$ apulse firefox" in a script or in a .desktop file for automation.
