 ctefx-r3di.bin

Hi Connor,

The bug was filed at Launchpad [1], I think the most notable error is
[    3.768667] snd_hda_intel 0000:00:1f.3: Direct firmware load for  
ctefx-r3di.bin failed with error -2

The firmware is indeed listed in patch_ca0132.c, but looks like there’s no  
corresponding file in linux-firmware.

Can you please take a look at the bug?
