Hi, I'm developing a LFS system and since I installed Pulseaudio-0.9.21 I'm running with some problems to play audio on my box. I first notice this when I started gnome and no sound applet was showed in the Notification area, so I thought at first that this was related to gnome, but after reading and talking with some friends on #gnome (irc.gimp.org) I saw that the problem was with pulseaudio not being loaded properly so the Sound apple (gnome-volume-control-applet) was trying to connect to pulseaudio daemon and like no connection could be made it tries and tries and keep trying to connect and this is why it wasn't showing: $ gnome-volume-control-applet ** (gnome-volume-control-applet:1369): WARNING **: Connection failed, reconnecting... ** (gnome-volume-control-applet:1369): WARNING **: Connection failed, reconnecting... So I tried to ran pulseaudio with -vvvv option, this is the output: $ LANG=c pulseaudio -vvvv I: main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted I: main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted D: core-rtclock.c: Timer slack is set to 50 us.
