Microphone array not detected in linux

drildhar · July 19, 2025, 11:28am

Hello, i recently tried a couple of linux distro and finally settled on using fedora. However, there is a problem with the audio, specifically the microphone being undetectable, in all linux distros. A little bit of background, my laptop is HP Victus 15 and back when i was using windows, the microphone is detected as Microphone Array and can be used to record audio.

Some sites that i found:

Someone mentioned that the solution for the 2nd link requires to add device to quirks table, recompile kernel, and disable ALSA UCM. However, i don’t know if that applies here.

Here is some commands that i’ve run:

$ lspci -nn | grep Audio
01:00.1 Audio device [0403]: NVIDIA Corporation GA107 High Definition Audio Controller [10de:2291] (rev a1)
06:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Radeon High Definition Audio Controller [Rembrandt/Strix] [1002:1640]
06:00.5 Multimedia controller [0480]: Advanced Micro Devices, Inc. [AMD] Audio Coprocessor [1022:15e2] (rev 60)
06:00.6 Audio device [0403]: Advanced Micro Devices, Inc. [AMD] Family 17h/19h/1ah HD Audio Controller [1022:15e3]

Based on the sites above, i suspect that the Audio Coprocessor is the microphone, but i don’t know how to prove that.

Good news! I found someone with the same laptop that has solved this issue in this link Ben Leskey | Fixing HP Victus 15 internal microphone drivers by compiling patched auto-updating kernel with openSUSE Tumbleweed Open Build Service. I currently have no idea how to auto-patch (if that were possible, temporarily until proper fix is found) the kernel to fix the microphone issue. If anyone knows how to do this, please reply! Any help appreciated. Thanks

anotheruser · July 19, 2025, 1:59pm

this has already been merged into the mainline kernel.

gnwiii · July 19, 2025, 2:09pm

Looks like the patch is in kernel 6.15.7: https://www.kernelconfig.io/config_snd_soc_amd_acp6x

There is Fedora build in Koji: https://koji.fedoraproject.org/koji/buildinfo?buildID=2750317

drildhar · July 19, 2025, 2:11pm

Ah yeah my bad, i forgot to add context. My DMI_PRODUCT_NAME is Victus by HP Gaming Laptop 15-fb1xxx. Due to this single digit (fb1xxx, not fb2xxx), my laptop isn’t detected and so I want to patch the kernel myself. If possible, I want to make it available to upstream kernel too.

drildhar · July 20, 2025, 3:38am

I found the exact solution for my laptop but it involves building a custom kernel which i don’t know how to do that. Possible fix for built-in mic no detection on HP Victus Laptop series / Multimedia and Games / Arch Linux Forums. If anyone knows, please help! Thanks

grumpey · July 20, 2025, 12:15pm

I would start with the below.

gnwiii · July 20, 2025, 12:15pm

Did you try the Koji build of 6.15.7? If it doesn’t work you should report that so it gets fixed before release.

drildhar · July 20, 2025, 2:04pm

I’ve recently tried this, but unfortunately the microphone didn’t show up at all. All commands that i’ve run is exactly the same as my first post. Is that a bug? Should I report it?

computersavvy · July 20, 2025, 2:39pm

There are 2 commands that may provide additional information about the microphone and aid in troubleshooting.

(you posted the result of one above [without the -k option], but the other has not been posted)
lspci -nnk and lsusb.
Even though internal, the mic might be on the usb bus.

drildhar · July 20, 2025, 4:11pm

This is taken using fedora default latest kernel (same as first post)

Where did which “it” not show: snd_pci_acp6x in inxi -A or in the GUI?

The “Possible fix” checks for your specific laptop model, but kernel devs prefer methods that use the specific ID of the microphone array. Did you check for your model with modinfo snd_pci_acp6x? I hoped to see a line like:
alias: pci:v00001022d000015E3sv*sd*bc04sc80i00*. Maybe an issue was discovered with the proposed fix.

I built custom kernel by following the fedora docs with the patch and finally the microphone works properly. Now, here are the commands that I’ve run while in the custom kernel. I’m gonna try the Koji kernel after this.

From the modinfo output, it appears that the patch removes support for all the other devices, which may mean additional logic is needed to handle the full range. I assume that should be done eventually by the vendor(s) as part of the normal process when releasing a new product, so glad you have a workaround.

Hello please I have the same problem from months can you guide me step by step? I’m the author of this thread: HP Victus 15-fb0160nf Microphone not detected on Fedora 41 Workstation

Have you tried upgrading to Fedora 42 and the recently released 6.15.7 kernel?

anotheruser · August 3, 2025, 4:03pm

patch is queued for the next 6.15.10 kernel

iksnorten · August 3, 2025, 5:12pm

Sorry my English and technical abilities are very limited but what does “patch is queued” means?

The patch for the kernel will be in effect when kernel 6.15.10 comes out. Simply, you just need to wait until kernel 6.15.10 gets released, update your system kernel, and done.
