Dell XPS 13 (9343) alsa unable to find pch audio card for Kernel 4.11

So after a recent update I find that yet again sound has been broken for my xps 13.
This time alsa has lost my pch sound card, yet it still appears in lspci

$ lspci -v | grep -A8 Audio
00:03.0 Audio device: Intel Corporation Broadwell-U Audio Controller (rev 09)
	Subsystem: Dell Device 0665

However aplay -L does not appear to find the card

$aplay -L

I believe that I have all the right modules

Any ideas?

Anything in dmesg? if ALSA doesn't find the card it's likely to be a kernel issue, try to downgrade to the last kernel and if that fixes it, try to bisect the bad commit and open a corresponding bugreport upstream.-

Re: Dell XPS 13 (9343) alsa unable to find pch audio card for Kernel 4.11

$ dmesg | grep audio
[    1.770088] snd_hda_intel 0000:00:03.0: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915])

This doesn't help me. I will try downgrading the kernel and see if that fixes anything

You might rather want to grep for

dmesg | grep -iE 'snd|hda|alsa'

Re: Dell XPS 13 (9343) alsa unable to find pch audio card for Kernel 4.11

Okay this looks much more helpful

$ dmesg | grep -iE  'snd|hda|alsa' 
[    1.729316] snd_hda_intel 0000:00:03.0: enabling device (0000 -> 0002)
[    1.729452] snd_hda_intel 0000:00:1b.0: enabling device (0000 -> 0002)
[    1.732806] snd_hda_intel 0000:00:1b.0: no codecs found!
[    1.770088] snd_hda_intel 0000:00:03.0: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915])
[    1.785954] input: HDA Intel HDMI HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:03.0/sound/card0/input7
[    1.785972] input: HDA Intel HDMI HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:03.0/sound/card0/input8
[    1.785990] input: HDA Intel HDMI HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:03.0/sound/card0/input9
[    1.786007] input: HDA Intel HDMI HDMI/DP,pcm=9 as /devices/pci0000:00/0000:00:03.0/sound/card0/input10
[    1.786025] input: HDA Intel HDMI HDMI/DP,pcm=10 as /devices/pci0000:00/0000:00:03.0/sound/card0/input11

So it looks like I'm failing to load the snd_hda_intel codec, but lsmod lists it...
Any reccomendations?

I have an XPS 13 9343 like the OP and sound works fine with linux 4.14.8-1.
