I've installed ArchLinux on a Dell XPS 15 L521X. For some reason when Gnome boots it finds no audio devices.If I switch to a virtual terminal and use the terminal based music player cmus to play some music, all of a sudden they appear.  The devices in question:mike@longshot:~  lspci -nn | grep -i audio00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)01:00.1 Audio device [0403]: NVIDIA Corporation GK107 HDMI Audio Controller [10de:0e1b] (rev ff)Interestingly, even running that lspci -nn | grep -i audio command causes Gnome to suddenly find the audio devices. How can I get Gnome to reliably find these devices by itself on startup?
