Same old trick to this one

1. Edit the pulse rules

sudo gedit /lib/udev/rules.d/90-pulseaudio.rules

add the following line

SUBSYSTEMS=="pci", ATTRS{vendor}=="0x1412", ATTRS{device}=="0x1712", ATTRS{subsystem_vendor}=="0x1412", 
ATTRS{subsystem_device}=="0xd634", ENV{PULSE_PROFILE_SET}="m_audio-audiophile-2496.conf"

2. Create the following file

sudo gedit /usr/share/pulseaudio/alsa-mixer/profile-sets/m_audio-audiophile-2496.conf

; M-Audio Delta Audiophile 2496
;
; This card, based on the Via ICE1712 chipset, has two stereo audio channels
; (1 in and 1 out) and a separate S/PDIF digital stereo channel. Like with
; all ICE1712-based cards, this is exposed by ALSA as a single 10-channel
; device with some of the channels not connected.
;
; See default.conf for an explanation on the directives used here.

Don’t forget to turn up the device DAC 0,1

optionally, if this setting goes after reboot, make a startup script and put the following into it

amixer -c 0 sset  'DAC',0 100% 100%
amixer -c 0 sset  'DAC',1 100% 100%

Note* -c 0 might change depending on your setup!
