TAS2781: Firmware Fails to Load

Part Number: TAS2781

Tool/software:

Hi,

I'm attempting to run Arch on a Lenovo X12 Gen 2 tablet. Audio works with headphones, but the built in speaker fail to output audio. When checking dmesg and journalctl for errors I found these related to the TAS2871:

$ sudo dmesg | grep TAS
[    4.562429] tas2781-hda i2c-TIAS2781:00: Direct firmware load for TAS2XXX2326.bin failed with error -2
[    4.562434] tas2781-hda i2c-TIAS2781:00: tasdevice_dsp_parser: load TAS2XXX2326.bin error
[    4.563870] tas2781-hda i2c-TIAS2781:00: dspfw load TAS2XXX2326.bin error
....

[ 12.208012] tas2781-hda i2c-TIAS2781:00: tasdevice_prmg_load: Firmware is NULL
[ 151.850002] tas2781-hda i2c-TIAS2781:00: tasdevice_prmg_load: Firmware is NULL

I am running kernel 6.13.1.

Linux archbpm 6.13.1-arch1-1 #1 SMP PREEMPT_DYNAMIC Sun, 02 Feb 2025 01:02:29 +0000 x86_64 GNU/Linux

Is there a mechanism to make the firmware available? This is what is currently available after installing Arch and supporting package.

ls /lib/firmware | grep TAS
TAS2XXX1EB30.bin.zst
TAS2XXX1EB31.bin.zst
TAS2XXX1EB3.bin.zst

We are upstreaming the bin file to Linux Community. We will cc you mail with which you registered.

Thank you. I was copied on the patch email and the merge update. Is there any guidance on how I can use the firmware, or load the required parts of the patch to my test machine ahead of this being part of a main line kernel release?

Thanks!

Does your machine work now? If so, I will transfer your new request to our audio acoustic expert. One more thing, have you download the PPC3 tool for your machine, which to make the coef.bin file?
