# 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.
