TAS2781 firmware is missing

[arkc80087]

Hello, this is my first post, so please let me know if there's anything I'm missing.

---

Switching over to Gentoo, I've noticed that 2 of my speakers failed to play sound, and only 1 speaker directly below my laptop's screen was playing. As a result, I could only hear the higher frequencies from my speakers.

It seems like there's a TAS2781 speaker amplifier inside of my laptop, which seems to not work due to missing firmware in the /lib/firmware directory.

arkc80087,

Welcome to Gentoo Forums!

I can see you have a (brand new) MeteorLake machine ... a Dell machine. I am unsure if I can help, because ... what I do when I get new error messages is: googling for it. So I googled for "TAS2XXX0C96.bin" ... and Google gave me 0 result

Next was googling "TAS2781 firmware" and "TAS2781 dell". I found this patch: https://lore.kernel.org/lkml/2024101107 ... @ti.com/T/ from 2024-october ... and it is already in 6.12.6

It is a bit strange that the driver is looking for a 0C96 and all firmware files from TI are already at 1EB3 and higher.

So, what we would need is the exact model of your machine and please do the "lspci" again with "-nnk" parameter, because of:
https://wiki.gentoo.org/wiki/User:Pieti ... lspci_-nnk

Please give us also a "dmesg | grep -i tas" (to get all messages from it)

Maybe your machine is too new ... and then you have to wait for new ... ... maybe you miss some options in your kernel ... so we would need your kernel .config and your (complete) dmesg (use wgetpaste for this as mentioned in above link).

Extra info

• The audio codec listed on the laptop manual is a Realtek ALC3254, which showed up as ALC295 on Windows 11 before, if I read it correctly back then (I do not have my Windows installation on my drive anymore, so I can't easily check it if I need to right now.)

[pietinger]

I see that you are a kernel expert and have configured your kernel perfectly. Your kernel is also partially hardened. I now see the exact model name: Dell Inc. Inspiron 16 7640

And unfortunately I only found 7620 and 7630 in the source code. This means it could really be that your model is not yet supported ... but ... I have already experienced crazy things with the communication of modules ... OR ... you must update your BIOS?

Why is it trying to load a firmware that doesn't exist? Maybe because it's a fallback and it wasn't told which firmware to load? Sometimes the communication between modules goes strange ways. I have already experienced that sometimes communication takes place via the DEBUG_FS [*] ... and that sometimes all MEI modules are needed to unlock something. So if all the following does not help, then you have to wait ... but it's worth a try.

(* yes, I am also not a fan of DEBUG_FS and I have it also disabled because of security reasons ... but unfortunately it is sometimes absolutely necessary ... if nothing helps, just disable it again)

Enable all these:

Code: Select all

# CONFIG_INTEL_MEI_TXE is not set
# CONFIG_INTEL_MEI_GSC is not set
# CONFIG_INTEL_MEI_VSC_HW is not set
# CONFIG_INTEL_MEI_HDCP is not set
# CONFIG_INTEL_MEI_PXP is not set

# CONFIG_I2C_CHARDEV is not set

# CONFIG_SPI_DESIGNWARE is not set

# CONFIG_SND_SPI is not set

# CONFIG_SND_DESIGNWARE_I2S is not set

# CONFIG_DEBUG_FS is not set

Save your current system log with “dmesg -t > kernel-log.old” beforehand and do the same afterwards so that we can compare the two.

Old dmesg log: https://dpaste.com/G5FBJAM2H

New dmesg log: https://dpaste.com/5QZNTZG74

(Not too sure about what happened to the timestamps in the old log.)

[pietinger]

(Not too sure about what happened to the timestamps in the old log.)

You did the first dmesg WITH parameter -t (as I wanted) ... and now WITHOUT ...
Please do NOW again WITH parameter -t so NO timestamps will be recorded ... AND THEN we can compare both logs

(but I have already seen that we have again the problem with that firmware file )

[Hu]

The timestamps can be stripped off readily enough, if you just want the ability to use diff. I think sed -e 's/^.\{15\}//' will work here, since the timestamps are all small enough that they remain within a fixed width.

[arkc80087]

Ah, I see, my bad.

Here's the new kernel log without timestamps.

https://dpaste.com/FK7RR9YHZ

[pietinger]

I feared it ... nothing has changed, except that now (of course) these messages are missing:

Code: Select all

intel-lpss 0000:00:15.0: Failed to create debugfs entries

The last thing you can check is: Boot with the latest UbuntuLiveCD and check everything as well: Does the sound work there? If yes, then we need (again) dmesg and lsmod (and the contents of /lib/firmware) after booting Ubuntu. If no (which I think), then we still have to wait for new versions of kernel and/or firmware.

Thank you very much, Hu. Saved it into my tips+tricks file

Sorry for the delay, got busy yesterday.

Here's the kernel config of the 24.10 Ubuntu LiveCD (in case we need it):
https://dpaste.com/C33HNPCSM

Here's the dmesg:
https://dpaste.com/C33HNPCSM

Kernel version: 6.11.0-8-generic

What I've noticed was that the TAS firmware messages were never seen in the live CD's dmesg.

Hmm ... you gave me the same link twice ...

The reason Gentoo kernel prints the loading of firmware into syslog is a special patch we have (Gentoo Linux -> [*] Print firmware information that the kernel attempts to load )

Have you looked into /lib/firmware of the Ubuntu ?

Also missing: "lsmod" from Ubuntu.

[arkc80087]

Sorry about the missing information and duplicate link.

---

Ubuntu 6.11 kernel config: https://dpaste.com/EUATATXL9

Ubuntu lsmod: https://dpaste.com/6JMGH46P7

Ubuntu firmware directory (full): https://dpaste.com/29BFMWXEF
Ubuntu firmware directory (ti/tas2781): https://dpaste.com/EVX2JU4WT

Ubuntu dmesg: https://dpaste.com/8MRUGZL8A

[pietinger]

Unfortunately I can't access your kernel .config anymore (because the link became invalid after one day), so you need to check if you have the following in your .config:

Code: Select all

INPUT_SOC_BUTTON_ARRAY
SERIAL_MULTI_INSTANTIATE
SND_HDA_SCODEC_TAS2781_I2C
SND_SOC_TAS2781_I2C
SND_SOC_TAS2781_FMWLIB
SND_SOC_TAS2781_COMLIB

(but I assume you have already checked all modules from the Ubuntu-lsmod for presence in your .config)

If so, there is still the possibility that Ubuntu applies some patches that are not yet in the kernel main line ... because the firmware file "TAS2XXX0C96.bin" does ALSO NOT exist in Ubuntu.

Apart from one difference, the output of the sound modules looks identical:

Code: Select all

Gentoo: sof-audio-pci-intel-mtl 0000:00:1f.3: Booted firmware version: 2.11.1.1
Ubuntu: sof-audio-pci-intel-mtl 0000:00:1f.3: Booted firmware version: 2.10.0.1

[arkc80087]

Didn't have INPUT_SOC_BUTTON_ARRAY and SERIAL_MULTI_INSTANTIATE in my kernel, but nothing different after enabling them in my kernel.

I think my best route would be to wait for an update to the firmware/kernel.
Should I submit this issue to Dell/TI or no need to?

[pietinger]

I think my best route would be to wait for an update to the firmware/kernel.

Yes, I think so too.

Should I submit this issue to Dell/TI or no need to?

No. If it works on Ubuntu then there is already software (kernel module/firmware) that works properly and TI's answer would just be that Gentoo is lagging behind. I even suspect that it is the kernel module itself, because in the firmware folder of Ubuntu I don't see any firmware (from TI) that we don't also have. In addition, the attempt to load a non-existent firmware with TAS2XXX0C96.bin is also an indication of a problem with the kernel module itself.

[arkc80087]

I see, thanks for the help though.

Hi, I also have no sound from the bottom speakers on a 7640. Nowadays I'm using Fedora though, I just found this thread using a search engine
I opened an issue on the sof GitHub repo a month ago: https://github.com/thesofproject/linux/issues/5271
Support by TI seems to be required for this, but personally I haven't done any further steps / contact attempts besides what I wrote inside this issue.
Maybe it would be good to post something on the TI audio forum?

Yeah, I think it'd be a good idea to post it to the TI audio forums. When I have some time, I'll try posting this on the TI forums.

TAS2781 is mentioned here: https://www.phoronix.com/news/Linux-6.1 ... d-Hardware

Thank you, in my case using that firmware + the patch from here got the bottom speakers working.

[arkc80087]

I can confirm that it works on my end as well now; just had to tweak the patch that d3d9 used to match my ID.

Thank you all for the help!
