As of f36afe4 (Linux-libre 3.16.3, eudev 1.9), the codec module of my
sound card doesn’t get loaded.

‘lspci’ identifies the device as:

--8<---------------cut here---------------start------------->8---
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)
	Subsystem: Dell Device 0492
	Flags: bus master, fast devsel, latency 0, IRQ 46
	Memory at e2e60000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 2
	Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
	Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
	Capabilities: [100] Virtual Channel
	Capabilities: [130] Root Complex Link
	Kernel driver in use: snd_hda_intel
--8<---------------cut here---------------end--------------->8---

To work around the problem, I end up running this sequence:

--8<---------------cut here---------------start------------->8---
# rmmod snd-hda-codec-analog snd-hda-codec-generic snd-hda-intel snd-hda-controller snd-hda-codec snd-hwdep snd-pcm snd-timer snd soundcore
rmmod: ERROR: Module snd_hda_codec_analog is not currently loaded
rmmod: ERROR: Module snd_hda_codec_generic is not currently loaded
# modprobe snd-hda-codec-idt
# udevadm trigger
--8<---------------cut here---------------end--------------->8---

This was also fixed by commit d460204 (so it’s a duplicate of
<http://bugs.gnu.org/18525>.)

Now I get this directly when booting:

--8<---------------cut here---------------start------------->8---
[    5.632899] snd_hda_intel 0000:00:1b.0: irq 30 for MSI/MSI-X

Closing the bug!
