Comment 6 for bug 459046

But.. if you've fixed yours in the way i've suggested, after pulse gets updated, just do:
sudo nano /lib/udev/rules.d/90-pulseaudio.rules

Add this as last 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"

Then "sudo alsa restart", and you're back on track. Sad little buggy this is.
