Cannot find soundcard driver [SOLVED]

I have been following the wiki page on ALSA in order to set up sound, but I cannot find what I assume to be the correct driver in menuconfig. My soundcard, according to lspci:

B10bot,

Its not where you have been looking.

Use the search. snd_hda_intel is correct.
In menuconfig, press / and enther snd_hda_intel
Press the number to the left of the item to go there.

So I went to the search and entered snd_hda_intel and found that I had already enabled it, just under a different name(HD Audio PCI). It was in Device Drivers ---> Sound card support ---> Advanced Linux Sound Architecture ---> HD-Audio. What now? Should it be a module instead? Is ALSA the problem?

B10bot,

You need to configure your codec driver as built in.
Until the codec leads, you can't tell which one you need. Its just bloat if you enable them all but otherwise harmless.

You can configure the codecs as <M> but don't do that. Its more difficult to make work.

While you have missing codecs, you will see something in dmesg about ... unable to bind to codec.
Once all the bits come together,

Does the modulization make any difference? Also do you have the same soundcard as me?

I am not sure if you have same sound card. You need to find out most likely Realtek.

also pastebin your dmesg.

I think a module is built so we can load it and unload it. However, for some reason when I built it in my sound didnt work.

I learned this because I built it in first ans when I read dmesg ALSA wasnt getting loaded made it a module and after that it was fixed.

lets see a couple of things first..

try command lsmod and post results; post results of dmesg | grep -i sound

also cat /usr/src/linux/.config | grep SND_HDA

Just to be clear, I am doing this from a already installed machine, so I'm unsure about how useful lsmod will be.
I'm pretty sure the driver is Realtek.
dmesg before your edits: http://dpaste.com/22RN4YN
dmesg after your edits: http://dpaste.com/0CYHNSZ
dmesg | grep -i sound before:

[ 1.514887] snd_hda_intel 0000:00:1b.0: bound 0000:00:02.0 (ops 0xffffffff9b08eb00)
[ 1.522399] hdaudio hdaudioC0D0: Unable to bind the codec
[ 1.522845] hdaudio hdaudioC0D3: Unable to bind the codec

That looks like the issue.

You have Alsa as a module or built in?

CONFIG_SND_HDA_I915 should be module

tmcca · Tux's lil' helper Joined: 24 May 2019 Posts: 120

here is my

take out
CONFIG_SND_HDA_I915=y make it [ ] I think that maybe issue as well the CONFIG_SND_HDA should be m not y as well the Alsa itself

Build all CONFIG_SND_HDA_CODEC_* to =y and let alsa pickup the good one for you, see https://forums.gentoo.org/viewtopic-p-6339697.html#6339697

My ALSA is a module. I found the CONFIG_SND_HDA_I915 in the search but I dont have a way to edit it. The search entry looks like this:

B10bot,

Lets stop working through a keyhole.
Please post the output of

NeddySeagoon:

So I made all the codec drivers built in, here are the outputs
lspci -knn output: http://dpaste.com/37C38RZ
/usr/src/linux/.config: http://dpaste.com/2J30F4J
dmesg output: http://dpaste.com/0VY6KXM

Side note: How do you get wgetpaste to go to pastebin.com? It isn't in the default options.

B10bot,

You only have one sound card. That's good. Sorting out multiple sound cards is an extra step.

So aplay -l and aplay -L both return devices now. The problem was that I did not mount my boot partion before running make install. Since it didn't return any errors I thought it was fine and therefore never had a kernel that fixed my problem. I narrowed the correct driver down to the Realtek one after I figured this out, so it works now. Thanks!

B10bot,

For completeness, you have two different places on you system called /boot.
When the boot partition is not mounted /boot refers the the directory on the root filesystem called /boot. Under these conditions, it should be empty.

You also have a boot partition (no leading slash). This is read by grub without mounting it. When grub runs, the concept of the file system tree does not exist.
When you want to update the boot partition, so grub can see the changes, it gets mounted at /boot (with the slash), hiding whatever was in /boot the directory on the root filesystem.

When you forget to mount /boot, your kernel is correctly installed to the wrong place. Its not an error to put files into the /boot the directory on the root filesystem.
Grub won't find them though.
