I could not find an rpm containing "hda-jack-retask" for CentOS 6.5, nor could I compile it from source as it requires newer libraries than CentOS provides. I therefore booted into Ubuntu 14.04, ran hdajackretask, and saved the pin reassignments that fix my particular laptop.

From Ubuntu 14.14 /lib/firmware/hda-jack-retask.fw

[codec] 0x111d76e0 0x103c190d 0

I created the following /etc/modprobe.d/hda-jack-retask.conf in CentOS 6.5:

options snd-hda-intel patch=hda-jack-retask.fw,hda-jack-retask.fw,hda-jack-retask.fw,hda-jack-retask.fw

Now when CentOS tries to load the snd-hda-intel module, I get the following error:

snd_hda_intel: Unknown parameter `patch'

Is there another method I can use to set the pins? This is the only way I've managed to get "Beats Audio" working on my HP Envy k025dx.

You need to rebuild your kernel with proper configs. The patch option is available via CONFIG_SND_HDA_PATCH_LOADER.

BTW, which pin setup is missing? It's better to add the static fixup in the kernel code.
