Recently I installed Ubuntu 20.04 on my Acer Swift 3 laptop.
The internal microphone doesn’t seem to work. Input Device drop-down menu is empty in Sound settings. But the external mic from earphones is detected and works fine.
Here are a few outputs that might be helpful,
reyansh@acer:~$ cat /proc/asound/card0/codec* | grep Codec Codec: Conexant Generic Codec: Intel Icelake HDMI
Multimedia audio controller output from
lspci -v command,
00:1f.3 Multimedia audio controller: Intel Corporation Smart Sound Technology Audio Controller (rev 30) Subsystem: Acer Incorporated [ALI] Smart Sound Technology Audio Controller Flags: bus master, fast devsel, latency 32, IRQ 164 Memory at 601d160000 (64-bit, non-prefetchable) [size=16K] Memory at 601d000000 (64-bit, non-prefetchable) [size=1M] Capabilities: <access denied> Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel, snd_sof_pci
Last few lines from /etc/modprobe.d/alsa-base.conf,
#Keep snd-usb-audio from beeing loaded as first soundcard options snd-usb-audio index=-2 #options snd-hda-intel model=auto options snd-hda-intel dmic_detect=0
I tried this but no luck.
Any kind of help will be greatly appreciated. Thanks!
