Manjaro on teclast f5 - sound not working and touchpad after resume

Support
1

I am here to show what works and what don’t work on this laptop Teclast F5 - TECLAST

Installation went without problem.

I needed to upgrade the kernel to have wifi working fine, now I am using kernel 5.13.11-1 and I have only this warning in dmesg

rtw_8821ce 0000:01:00.0: timed out to flush queue 1

Bluetooth works fine but using it to connect to my cell phone via tethering/bluetooth was not affordable.

Sound is not working as I cannot see the sound board. In dmesg I see these lines

[    4.012906] snd_hda_intel 0000:00:0e.0: DSP detected with PCI class/subclass/prog-if info 0x040100
[    4.418863] snd_hda_intel 0000:00:0e.0: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915])

The command

inxi -A

gives this result

But alsamixer shows only hdmi output and this does not work: I found something in 213065 – Gemini Lake snd-hda-intel no HDMI audio but I cannot check more.

Touchpad works fine but sometimes after the suspend it did not work.

I found some help in in this page about ubuntu on this laptop GitHub - ijonglin/teclast-f5-ubuntu-finalizer: Current HW/SW Kernel/System/ACPI Modifications To Get a $400 Dream Ubuntu Linux Laptop but trying to remove (along with i2c_hid_acpi) and reinsert i2c_hid module did not work

Oops, you are right.
My intention was to save this post as draft but I save it without actually asking nothing.

I’m sorry for being dumb, but I don’t understand:

  • lnoferin’s issue is solved
  • lnoferin’s issue is not solved
