How to find config options from module names? (For sound card NM10/ICH7)

How to find config options from module names? (For sound card NM10/ICH7)

[Naman Shekhar Mishra]

Hi,
I am using kernel 3.17.0 and need sound working with my Intel sound card
NM10/ICH7. I have "Sound card support" option turned on with ALSA and I am
trying to compile and install the card driver.

Card details:
$ lspci -nn | grep -i audio
00:1b.0 Audio device [0403]: Intel Corporation NM10/ICH7 Family High
Definition Audio Controller [8086:27d8] (rev 02)

lsmod output on a kernel with working sound:
$ lsmod | grep -i sound
soundcore              12600  2 snd,snd_hda_codec
$ lsmod | grep -i snd
snd_hda_codec_hdmi     46621  1
snd_hda_codec_realtek    70636  1
snd_hda_codec_generic    62873  1 snd_hda_codec_realtek
snd_hda_intel          29336  3
snd_hda_controller     30673  1 snd_hda_intel
snd_hda_codec         120485  5

snd_hwdep              13272  1 snd_hda_codec
snd_pcm                95778  4

snd_timer              28527  2 snd_pcm,snd_seq
snd                    57153  17

soundcore              12600  2 snd,snd_hda_codec

I tried searching for the device id in include/linux/pci_ids.h but it
wasn't there.
$ grep 27d8 include/linux/pci_ids.h
$

Can someone please tell me how to find all the config options for this
sound card?

Thanks,
Naman

$ git grep -i 0x27d8
[...]
sound/pci/hda/hda_intel.c:      { PCI_DEVICE(0x8086, 0x27d8),
$ git grep -w hda_intel.o
sound/pci/hda/Makefile:snd-hda-intel-objs := hda_intel.o
$ git grep -w snd-hda-intel
[...]
sound/pci/hda/Makefile:snd-hda-intel-objs := hda_intel.o
sound/pci/hda/Makefile:snd-hda-intel-$(CONFIG_SND_HDA_I915) +=  hda_i915.o
sound/pci/hda/Makefile:obj-$(CONFIG_SND_HDA_INTEL) += snd-hda-intel.o

So it seems you have to start with SND_HDA_INTEL. But its Kconfig help
contains this line:
    Don't forget to choose the appropriate codec options below.

I don't know how to choose those "appropriate codec options", sorry.

Hope this helps.
