linux-realtek-alc287's Issues

Did not work for me :( (Lenovo Legion 7 2021)

Tried the main patch, followed the instructions exactly and then rebooted. Opened up Lofi girl but alas. Tested on Ubuntu 20.04.2 with kernel 5.8.0-59-generic. However, it does seem that sound is recognised in Settings -> Sound -> Output (I think it wasn't recognised before this).

As a side note, the alternative 1 also didn't work. (In your instructions, verbs-working.txt is basically verbs-legion.txt right?)

How to make patch of other alc287 laptop

My friends have Legion laptop with same problem. But we found your patch not work for like Legion 7 2022. I know maybe I should make different patch for it. But could you tell me how?

Lenovo Legion 7 methods not working

Are there other requirements? Does this work with Pulse Audio? I'm using Pulse Audio for bluetooth headset compatibility.

Method 1 does nothing.

Method 2 returns an error:

sudo python3 realtek-verb-tools/applyverbs.py verbs-working.txt
Applying verbs...

Hi,

thank you for this patch.
I tried to apply it to my machine, it doesn't work at all, though according to dmesg patched is used:

python based patch(sudo python3 realtek-verb-tools/applyverbs.py verbs-legion.txt) fixes my sound but after reboot/suspend/just some amount of time sound disappear again. Any ideas why patched firmware doesn't work?

Is the patch by any chance also applicable to Lenovo Yoga 7?
