Intel Audio disappears

I have a MSI GS70 that has both intel and nvidia audio cards:

➜  ~ lspci|grep -i audio
00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 05)
01:00.1 Audio device: NVIDIA Corporation GK106 HDMI Audio Controller (rev ff)

recently the intel one stopped showing up:

➜  ~ sudo arecord --list-devices
**** List of CAPTURE Hardware Devices ****
➜  ~ aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)
pulse
    PulseAudio Sound Server
hdmi:CARD=NVidia,DEV=0
    HDA NVidia, HDMI 0
    HDMI Audio Output
hdmi:CARD=NVidia,DEV=1
    HDA NVidia, HDMI 1
    HDMI Audio Output
hdmi:CARD=NVidia,DEV=2
    HDA NVidia, HDMI 2
    HDMI Audio Output

any reason for this?  I've tried both with and without pulseaudio, but same results.  Perhaps it's the kernel:

Linux stealth 4.7.2-1-ARCH #1 SMP PREEMPT Sat Aug 20 23:02:56 CEST 2016 x86_64 GNU/Linux

Re: Intel Audio disappears

Still trying to work out what is going wrong, upon reinstalling arch my card was working right off the bat, but after installing all the desktop stuff and moving my user in I find it borked again.  There is no ~/.asoundrc and /etc/asound.conf is default, and all kernel mods appear to be loaded:

➜  ~ sudo lsmod|grep intel|grep snd
snd_hda_intel          32768  4
snd_hda_codec         106496  2 snd_hda_codec_hdmi,snd_hda_intel
snd_hda_core           65536  3 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel
snd_pcm                86016  4 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel,snd_hda_core
snd                    65536  14 snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_pcm,snd_hda_codec,snd_hda_intel

cat /etc/asound.conf 
# Use PulseAudio by default
pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

Re: Intel Audio disappears

I am seeing very similary issues on another machine of mine, this one greybox with an MSI mobo and NVIDIA card

lspci -vvn

It seems the NVIDIA is overtaking the Azalia controller?
