Pulseaudio is a brand new sound server system for linux.
command line
* list devices/clients: pactl list
- list ESOUND handlers
elwood ~ # eselect esd list Available ESounD implementations: [1] ESounD original * [2] PulseAudio elwood ~ # eselect esd set 2
Use flags
- list me the packages actually using pulseaudio use flag:
equery hasuse pulseaudio
- from how I've understood it, (I've been studying about several sound systems like oss,esd,alsa,sox specialized all in different branches of "the sound" and all are following the evolution of GNU projects)...
