工具与软件：

您好！

我正在尝试在 Lenovo X12 Gen 2平板电脑上运行 Arch。 音频可以与耳机配合使用、但内置扬声器无法输出音频。 检查dmesg和journalctl查看错误时、我发现这些与 TAS2871相关：

$ 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

我运行的是内核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

是否有提供固件的机制？ 这是安装 Arch 和支持包后当前可用的功能。
