I am writing my own greeter for lightdm based on https://github.com/surlykke/qt-lightdm-greeter.
I wanna to play sounds to notify user if the password is not right for authentication.
I use alsa to play sounds and this works fine when I have already logged in, but on the system login screen I can not play the sounds and get this error:
Can't open audio default: No such file or directory.
I use snd_pcm_open to open the audio device and pass "default" as the device name.
It seems like the audio device does not load if I am not log in.
