How did the sound card was configured? Was PipeWire used? Interesting that the headphones don't work. Check Chromebook/Sound_configuration.

Added some notes.

The bug with jack was known at least since 2022. When I've bought the laptop, I tried to connect wired headset and it did not work. For now I don't have any wired headset to test it.

My laptop has the same wireless card and is affected by the bug described here. Is this laptop also affected by it? I see you suggest to use iwlwifi.power_save=1, can you explain why? --Lars Hint (talk) 11:09, 25 March 2024 (UTC)

There was an issue where the card would pull 5W of power without this set, it needs more testing to see if this is still an issue to worry about in 6.x kernels but that's the history of it.

(BTW nice work around the wiki, please do consider joining #gentoo-wiki on IRC as we are all big fans of what you do around the wiki :) )

After almost two years of using this laptop it is not easy to remember, why I suggest this parameter. It seems, that I had an issue with power consumption. I will test later what happens if I remove this parameter, but I restart this laptop not often at all

Aruslantsev (talk) 07:29, 26 March 2024 (UTC)

Had time to check it today. Without this parameter power consumption is higher, but wifi still works and does not crash at any load

Sometimes laptop losts AX201 after resuming after suspend to ram with kernel >= 6.6.8-gentoo with throwing kernel bug with kernel NULL pointer dereference. After this system becomes unusable, and only reboot helps to fix this issue. I don't know what is the best way to provide this information in wiki, especially because this version is not available anymore. Of course I will provide this information in gentoo bugzilla and kernel bugzilla a bit later.
