Public bug reported:

$ lsb_release -rd
Description:	Ubuntu 14.04.1 LTS
Release:	14.04
--------

Sound has been troublesome on my system.

I noticed this happened twice. I have two different system settings
programs (because of the first time this happened). In one program (KDE
system settings), my soundcard is listed, in the other (Ubuntu's default
system settings),  it is not listed. I cannot play sound out of it with
graphical desktop programs, but `aplay
/usr/share/sounds/alsa/Front_Center.wav` does play sound fine.

I followed these instructions:
https://help.ubuntu.com/community/SoundTroubleshooting

`pacmd` looked fine. My chosen sound card had an asterisk next to it.

`aplay /usr/share/sounds/alsa/Front_Center.wav` ran as user fine

`sudo aplay -l` lists it accurately

`find /lib/modules/`uname -r` | grep snd` gave an appropriate driver:
/lib/modules/3.13.0-37-generic/kernel/sound/pci/echoaudio/snd-layla24.ko

`lspci -v | grep -A7 -i "audio"` showed my sound card:
03:00.0 PCI bridge: Pericom Semiconductor PI7C9X111SL PCIe-to-PCI Reversible Bridge (rev 02) (prog-if 00 [Normal decode])

	Subsystem: Echo Digital Audio Corporation Layla24
	Flags: bus master, medium devsel, latency 192, IRQ 18
	Memory at fa200000 (32-bit, non-prefetchable) [size=1M]
	Kernel driver in use: snd_layla24

I tried `modprobe snd_layla24` and `modprobe snd-layla24` with no
difference being made.


I tried adding it to /etc/modprobe.d/alsa-base.conf, but it still doesn't show up in the ubuntu system settings (gnome I think), which I think is the one that determines if it'll play through regular desktop applications or not (7th to last line snd_layla24):
