What audio driver for intel multimedia soundcard?

I recently installed arch on an asus T102h tablet. I'm really happy with how well it's worked - almost everything is working perfectly. But I can't get any sound.

lshw -C sound shows:

  *-multimedia UNCLAIMED    
       description: Multimedia controller
       product: Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series Imaging Unit
       vendor: Intel Corporation
       physical id: 3
       bus info: pci@0000:00:03.0
       version: 36
       width: 32 bits
       clock: 33MHz
       capabilities: pm msi cap_list
       configuration: latency=0
       resources: memory:91000000-913fffff

So it looks to me like I don't have a driver for that device. If I run lsmod | grep snd:

snd_intel_sst_acpi     16384  0
snd_intel_sst_core     69632  1 snd_intel_sst_acpi
snd_soc_sst_mfld_platform    86016  1 snd_intel_sst_core
snd_soc_sst_match      16384  1 snd_intel_sst_acpi
snd_soc_core          196608  1 snd_soc_sst_mfld_platform
snd_compress           20480  1 snd_soc_core
snd_pcm_dmaengine      16384  1 snd_soc_core
snd_pcm                90112  3 snd_pcm_dmaengine,snd_soc_sst_mfld_platform,snd_soc_core
snd_timer              28672  1 snd_pcm
snd                    65536  5 snd_compress,snd_timer,snd_soc_sst_mfld_platform,snd_soc_core,snd_pcm
soundcore              16384  1 snd
ac97_bus               16384  1 snd_soc_core

I don't know much about audio drivers but the snd_intel_sst_acpi module looks to me like it's probably the one that's supposed to be controlling the device. I suspect I might need a different version, or something like that, but I can't find any information on those modules.

I have the default alsa installation that arch installs with. I tried searching alsa's wiki and intel's website but found nothing for my device.

also, uname -r:

4.10.1-1-ARCH

aplay -l:

aplay: device_list:270: no soundcards found...

ls /dev/snd:

seq  timer

dmesg: http://pastebin.com/ygV35J5L
Of which, this seems maybe relevant:

WARNING: CPU: 2 PID: 212 at drivers/i2c/busses/i2c-designware-baytrail.c:106 baytrail_i2c_acquire+0x139/0x1f0 [i2c_designware_platform]

I'm stuck. Does anyone know if there's a driver I need or something else that's going on? Thanks!

Re: What audio driver for intel multimedia soundcard?

Your processoor appears to be a cherrytrail / baytrail type, and those tend to be poorly supported by linux.

The freeze may be related to this kernel bug #109051 .

As for the soundcard you can try with the latest kernel (linux-mainline in AUR ) or with  a patched kernel like aur linux-ct .

Keep in mind you will be using experimental stuff, things could go wrong easily.

Re: What audio driver for intel multimedia soundcard?

"Imaging Unit" sounds like camera to me. There's some snd_soc_sst stuff loaded so probably the SOC/CPU has integrated (outside of PCI) soundcard of some sort but it doesn't work because reasons. Run dmesg and see what this driver says when it loads.
