I've recently installed Ubuntu 20.04 on my new Asus BX425EA (in dual boot with Windows). So far, so good, everything seems to work fine. Except when I use my headphones, I have a crackling sound. Also, if the sound level is low, I got interruptions.

With the laptop internal speakers, no issue. Also, I tried with another headphones Bluetooth connected (not mine, I borrowed it), no issue. My headphones don't have Bluetooth, I can only connect it with the wire. But the thing is, the laptop does not have 3.5mm audio jack plug: there is a USB-C to jack adapter (furnished with the laptop, see images). So, I'm pretty sure the issue is with this adapter.

I've already tried a buch of things without sucess:

Here is some information:

$ cat /proc/asound/card0/codec* | grep Codec
Codec: Realtek ALC294
Codec: Intel Tigerlake HDMI

And:

$ dmesg | grep usb

  • Perhaps you are facing this bug. You can try this workaround. It works for me, though my headphones do have 3.5 mm audio jack. Feb 22, 2021 at 19:19
  • I mean my laptop also has 3.5 mm audio jack plug. Feb 22, 2021 at 19:31
  • Hi, thanks for the suggestion. Actually I tried but after the execution, Terminal gives me: nid = 0x20, verb = 0x500, param = 0x67 value = 0x0 nid = 0x20, verb = 0x400, param = 0x3000 value = 0x0 So, I'm not sure the commands executed properly. And problem is still here.

After days of trials without success, I've taken the risk to buy the Apple USB-C to 3.5mm jack adapter (10€ on the French Apple Store). Based on this post, I had a little hope it would work. And I guess I'm lucky because the sound is crystal clear! Plug and play, nothing to configure.
