Dear list, I have spent now many hours trying to understand why pulseaudio is not working when I boot with systemd, but works when booting with sysvinit. I found the culprit could be this: [gabx@magnolia:~]$ aplay -l aplay: device_list:252: no soundcards found... What is strange is that all my devices are recognised and modules loaded. $ lspci -v 01:00.1 Audio device: NVIDIA Corporation GF114 HDMI Audio Controller (rev a1) Subsystem: ASUSTeK Computer Inc. Device 838b Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at fa080000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) Subsystem: ASUSTeK Computer Inc.

E: [pulseaudio] main.c: pa_pid_file_create() failed. when I open the volum control in XFCE panel: GStreamer was unable to detect any sound device. Some sound system specific GStreamer package maybe missing. It may also be a permissions problem. To sum up, I don't understand why my sound devices are not recognized. I may have misconfigured something in systemd set up, but I have no idea. Thank you for your help, as this is the only issue when booting with systemd.
