Re: [SOLVED] ALSA: no input through internal microphone (Ryzen 6000)

I also had the same problem on my brand new Thinkpad P14s (AMD) Gen4 Type 21K5, produced in March 2024. Pavucontrol was reporting the internal mic as Microphone (unplugged). I've built the current kernel version 6.8.2-arch2-1 with the following patch (which is kinda borked, a diff adding a separate LENOVO / 21K5 section to the quirks array would be nicer. but anyway):

diff --unified --recursive --text a/sound/soc/amd/yc/acp6x-mach.c b/sound/soc/amd/yc/acp6x-mach.c

                }
        },

Additionally to make it work, I had to turn off ucm as pointed out by others. I've created the following file ~/.config/wireplumber/main.lua.d/50-alsa-config.lua:

alsa_monitor.rules = {
  {
    apply_properties = {
      ["api.alsa.use-ucm"] = false,
    },
  },
}

Many thanks to the posters in this thread, as I would't have come up with the solution on my own, and a working microphone was kind of crucial for me.

The above patch also fixed the microphone issue I had with my Z16 gen 2. Also, this patch appears to now be in place in 6.8.3: https://github.com/zen-kernel/zen-kerne … mach.c#L59. It will likely be hitting arch shortly.

I am having the exact same issue I think.

I also tried to see the if there were any message in dmesg for this device with

sudo dmesg | grep '\(acp6x\|DMIC\)'

but the there was no output of this command. All this while i was thinking that this ALC285 is my laptop's internal microphone but as pointed out by zdbiohazard that this may be speakers or jack or hdmi so i was may be barking up the wrong tree this whole time and my internal microphone may not have even loaded up by the kernel I am still not 100% sure that this is the reason for my problem. I created a post for this issue here https://bbs.archlinux.org/viewtopic.php?id=298290. PS my laptop is ASUSTeK COMPUTER INC. ROG Zephyrus G14 GA401IHR_GA401IHR

$ uname -a
Linux dusty 6.10.2-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 27 Jul 2024 16:49:55 +0000 x86_64 GNU/Linux

i am even on kernel 6.10 but i think there is no patch for my laptop

Re: [SOLVED] ALSA: no input through internal microphone (Ryzen 6000)

Thanx guys for information, it works for my Redmi G Pro 16 2022 Ryzen 6800 laptop

then add configuration file for wireplumber
/home/user/.config/wireplumber/wireplumber.conf.d/51-alsa-pro-audio.conf
and restart services
