Audio backend

As Telegram makes use of OpenAL, it is possible to configure the audio settings by editing its config files, i.e. , or the environment variables listed here.

In case sound is not working due to an invalid audio backend being used, it can be overwritten by setting the environment variable or the property in the [general] section of the OpenAL config. The drivers value for example would try pulseaudio first and then fallback to the default driver list.

On environments where the environment variable is unset (like when not running desktop environments, i.e only window managers) telegram-desktop falls back to a very basic file browser. Using the above mentioned variable, the user can change the default one to the one they like that belongs to a certain desktop environment. Valid values for this variable can found here. For example to use Thunar from the XFCE project:

gollark: That *might* not be a *terrible* way to do it.

gollark: It could, yes.

gollark: It strips all markdown except wikilinks, even.

gollark: There is, yes.

gollark: It reminds me of this great pairing.
