[SOLVED] No sound with Intel CM238 HD Audio

Message

egrep,

dmesg is missing.

Its certainly a kernel issue as

00:1f.3 Audio device [0403]: Intel Corporation CM238 HD Audio Controller [8086:a171] (rev 31)
	Subsystem: Lenovo CM238 HD Audio Controller [17aa:3803]
	Kernel driver in use: snd_hda_intel
	Kernel modules: snd_hda_intel

is correct and you still don't have any sound devices.

Why do you think that

Code: Select all

CONFIG_SND_HDA_CODEC_REALTEK=m

is the correct codec?

@egrep: did you update GRUB configuration after installing the kernel?

fturco,

dmesg will tell :)

I'm sorry for the missed dmesg output. Here it is: https://pastebin.com/raw/mKV7rT0z

It was just may try because of this:

from what I understand).

Yes, I should disable this of course.

I did this once when I updated the kernel version.

Btw, Lenovo says this is Realtek: https://pcsupport.lenovo.com/us/en/prod ... s/DS120220

egrep,

Code: Select all

[    0.000000] Linux version 5.7.10-gentoo (root@saturn) (gcc version 10.2.0 (Gentoo 10.2.0 p1), GNU ld (Gentoo 2.34 p4) 2.34.0) #31 SMP Fri Jul 24 18:51:26 EEST 2020

Thats 31 kernel builds and this one was built at Fri Jul 24 18:51:26 EEST 2020.
Good. Many people with sound problems are not running the kernel they think they are. Thats not you though.

Code: Select all

[    1.356128] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915])

Thats the the HDMI output but there is no entry in /dev/snd for it.

Code: Select all

[    1.488692] snd_hda_intel 0000:00:1f.3: CORB reset timeout#1, CORBRP = 0

comes from ./sound/hda/hdac_controller.c
The code is

Code: Select all

        for (timeout = 1000; timeout > 0; timeout--) {
                if (snd_hdac_chip_readw(bus, CORBRP) & AZX_CORBRP_RST)
                        break;
                udelay(1);
        }

Either something is missing, or the timeout is not long enough for your hardware. I suspect the former.
If you want to try a longer timeout, change the timeout = 1000 for a bigger number and rebuild the kernel.

There is this kernel bug report.

Code: Select all

[    1.490220] snd_hda_intel 0000:00:1f.3: no codecs found!

is consistent with having some other codec that the one in the kernel.
Enable them all as modules. It may not matter unless that timeout is fixed.

Does this happen on a power on boot or resume from suspend or both?

Educated shot in the dark ... add the INTEL_LPSS options to your kernel.
There are about half a dozen.

Don't use

Code: Select all

[    1.571293] ntfs: driver 2.1.32 [Flags: R/W MODULE].

It won't do what you think it does but al least it no longer trashes NTFS filesystems.

Changing sound/hda/hdac_controller.c does not help at all.

I changed it a bit from:

Code: Select all

int timeout;

for (timeout = 1000; timeout > 0; timeout--) {
  if (snd_hdac_chip_readw(bus, CORBRP) & AZX_CORBRP_RST)
    break;
  udelay(1);
}
if (timeout <= 0)
  dev_err(bus->dev, "CORB reset timeout#1, CORBRP = %d\n",
	  snd_hdac_chip_readw(bus, CORBRP));

to:

Code: Select all

int timeout;
int reads = 0;

for (timeout = 100000; timeout > 0; timeout--) {
  reads++;
  if (snd_hdac_chip_readw(bus, CORBRP) & AZX_CORBRP_RST)
    break;
  udelay(1);
}
if (timeout <= 0)
  dev_err(bus->dev, "CORB reset timeout#1, CORBRP = %d (performed reads: %d)\n",
	  snd_hdac_chip_readw(bus, CORBRP), reads);

Now dmesg looks as follows:

Code: Select all

$ dmesg -w | grep snd_hda_intel
[    1.365090] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915])
[    1.658443] snd_hda_intel 0000:00:1f.3: CORB reset timeout#1, CORBRP = 0 (performed reads: 100000)
[    1.659746] snd_hda_intel 0000:00:1f.3: no codecs found!
[    2.445595] snd_hda_intel 0000:00:1f.3: CORB reset timeout#1, CORBRP = 0 (performed reads: 100000)

I've tried setting "snd_hda_intel.single_cmd=1" and "snd_hda_intel.probe_mask=1" as proposed here, but this does not change anything.

Adding "intel_idle.max_cstate=0" and "intel_pstate=disable" boot options as mentioned here changes nothing.

egrep,

There is lots of good reading in
/usr/src/linux/Documentation/sound/hd-audio
In particular, notes.rst and models.rst. Start with notes.rst.

Both files give module parameters you can pass to
snd_hda_intel when it loads.

As you have CONFIG_SND_HDA_INTEL=m and CONFIG_MODULE_UNLOAD=y, that makes life easy.

Do

Code: Select all

modprobe -r snd_hda_intel

That will fail if other modules are using snd_hda_intel, they must be removed first.
Its a bit of trial and error but lsmod can help.

Once snd_hda_intel has been removed, it can be reloaded with

Code: Select all

modprobe snd_hda_intel <some list of parameters>

Code: Select all

modinfo snd_hda_intel

will show a list of possible parameters.
It will make you head hurt, as one invocation of modprobe snd_hda_intel can be used to set up lots of HD-Audio cards differently, hence the Array of ...

Once snd_hda_intel is reloaded, have a look at the end of dmesg. You want the timeout message to have gone away and your codec to be detected.

Rinse and repeat for the next

Code: Select all

modprobe snd_hda_intel <some list of parameters>

that you want to try.

I'm pleased that its working but I don't understand what resetting the CMOS did.

NeddySeagoon,

I decided to check if it would work after reading this comment. It was just a theory. However, it looks like it works. It is interesting that I have never changed the CMOS settings before.

You don't actually need all of this.

All you have to do ( for me at least ) was the enable CONFIG_SND_HDA_CODEC_REALTEK in:

Code: Select all


-> Device Drivers              
                                                                                     
         -> Sound card support (SOUND [=y])                                                                                          
           -> Advanced Linux Sound Architecture (SND [=y])                                                                           
             -> HD-Audio

                     <*> Build Realtek HD-audio codec support

You can also enable these just to be sure:

Code: Select all


CONFIG_SND_HDA_INTEL
CONFIG_SND_HDA_HWDEP
CONFIG_SND_HDA_RECONFIG
CONFIG_SND_HDA_INPUT_BEEP
CONFIG_SND_HDA_PATCH_LOADER
CONFIG_SND_HDA_GENERIC

Also I don't really think taking out and putting back your CMOS battery really does anything since I didn't do it and it worked.
