mic not working in HP laptop

Could you guys please help me make the mic in my new laptop work? HP 14s-dq2012ur , MX Linux AHS, XFCE. When I first installed the system, the sound wasn't working, I tried the trick from this forum

Code: Select all

echo 'options snd-intel-dspcfg dsp_driver=1' | sudo tee -a /etc/modprobe.d/sound.conf
and it helped. But I can't get the mic to work on my own. Not a very experienced Linux user here. The mic from the earphones works, the stereo mic from the laptop doesn't. ALSA says there's only 1 Input device, Microphone (unplugged)

With applications like Zoom, you may have to configure which input to use within the application itself.

Yes, but that's already a known side-effect of that parameter. So, you must've seen either that note & workarounds in the same thread / post (by me)

... like adding model=xxx in the options..


You can do this: First disable that file to prevent confusions (rename it to ...conf.old ) :

Code: Select all

sudo mv /etc/modprobe.d/sound.conf /etc/modprobe.d/sound.conf.old

Then from "MX Package Installer" , Test repo tab, install the latest 5.14 kernel and try the sound when booted with that ...

Tried to do that, Zoom just gives me 2 options to choose from, Analog Stereo or Same As System, neither option works (inbuilt mic doesn't work). Zoom works fine when I plug my headphones with mic in.

Did that, renamed the file, then installed kernel 5.14 ("Liquorix"), but still no result. Alsa mixer still shows Input Devices: Port: Microphone (unplugged).

What about sound? (with 5.14)

( Also , just to make it sure: In Alsamixer you did this, right? : F6 "Select sound card" , then F5 "All" )

Sound continued to work after kernel change (although I lost wifi again, as after MX was installed fresh, and had to reinstall wifi package).
When Alsamixer starts in Terminal first, there's just Master, press F5, now there's L R Capture bar (in the reds). This laptop has left and right mics, hence L & R.
If I choose another sound card with F6 (Chip Realtek ALC236), there are two bars for Mic Boost, also both in their red zones.
But still no luck with the mic :)

But... rtl8821ce is present in the kernel by default :

Code: Select all

$ modinfo rtl8821ce
filename:       /lib/modules/5.10.0-9-amd64/updates/rtl8821ce.ko
version:        v5.5.2.1_35598.20191029
author:         Realtek Semiconductor Corp.

...
Even in 4.9 :

Code: Select all

$ modinfo rtl8821ce
filename:       /lib/modules/4.9.0-276-antix.1-amd64-smp/updates/rtl8821ce.ko
version:        v5.5.2.1_35598.20191029

...
Meanwhile, particularly first F6 select Intel (rather than "default") , then F5 after that.

(Also select (and Apply) Intel in "MX Select Sound" from Menu )

No idea!

Got tired of fighting that mic issue, decided to reinstall the operating system, right at the time when MX21 came out, so I installed it. Wifi, sound, mic now all work from fresh installed OS, no hassle

Glad to hear all are fine now :)

(Though this is also odd: 5.10.0-5 vs. 5.10.0-9 only )
