Internal mic not work, AMD laptop, MSI Alpha 17 C7V

SmileYik · 2024-09-09 12:06:26

I got a new AMD laptop these days and installed archlinux on it. And i found that the internal mic can't record voice.

I tried any suggestion on wiki but they are not work. After that, I found some post like https://bbs.archlinux.org/viewtopic.php?id=278886, https://forum.manjaro.org/t/built-in-mi … x/152373/2.

The issue in the post is similar with mine, and I try to patch kernel as same as these posts, but it is not work to me, too.

After i tried patch kernel, I found that their driver of “AMD ACP/ACP3X/ACP6x Audio Coprocessor vendor” is different to me, theirs is snd_pci_acp6x, mine is snd_rpl_pci_acp6x.

Please let me know if you have any suggestions on how to approach this further.

After I put snd_rpl_pci_acp6x to blacklist. It's noting changed but driver of "AMD ACP/ACP3X/ACP6x Audio Coprocessor vendor" turned to N/A.
It's there has some way to change it's driver to "snd_pci_acp6x"? I really don't know how to solve it

Hi, did you ever get this working, I have the same problem. After long hours, I've noticed that even though we have the same device id as the snd_pci_acp6x driver, we don't have the same revision which I'm my case it's 62 and I'm yours it must be since snd_rpl_pci_acp6x there is a hardcoded revision check. Although I've searched I can't seem to find an answer, although I'm on day 2 on this journey, but now the kernel is 6.18.3 and it's still doesn't seem to work. Just for completeness I'm running an HP omen 16 AMD 8940hx laptop.
