No microphone sound in Librewolf and Firefox too

bimon · 2022-02-01 17:45:22

Hello,

I have sound working fine in Zoom (both Mic and Headphones), but unfortunately there is no microphone sound in Firefox.
On the other hand Firefox plays any sounds to the headphones fine.

It is a Chimaera installation.

dpkg -al | grep pulse
ii libpulse-mainloop-glib0:amd64 14.2-2 amd64 PulseAudio client libraries (glib support)
ii libpulse0:amd64

I have following asound.conf:

root@chimaera:/etc/alsa# cat asound.conf

##### Hardware Aliases #####

pcm.system_card {
        type hw;
        card 0;
}

ctl.system_card {
        type hw;
        card 0;
}

ctl.system_dm ctl.system_card;

I have found a workaround of executing browser by apulse command.

But then why headphones work even without apulse via ALSA while microphone works only via apulse for me ?

So I presume it works without apulse if you remove asound.conf?

Removing /etc/alsa/asound.conf still keeps sound in zoom working, but it does not influence firefox at all, so Mic still does not work anyway.

Is /etc/alsa/asound.conf file taken into account by the ALSA at all?

Can you please suggest an URL with modern guides for custom configuration of ALSA in Debian v11 or Chimaera without pulseAudio?

Maybe this one.

I don't think so.

From /usr/share/alsa/alsa.conf:

# pre-load the configuration files

@hooks [
   {
      func load
      files [
         "/var/lib/alsa/conf.d"
         "/usr/etc/alsa/conf.d"
         "/etc/alsa/conf.d"
         "/etc/asound.conf|||/usr/etc/asound.conf"
         "~/.asoundrc"
         {
            @func concat
            strings [
               {
                  @func getenv
                  vars [
                     XDG_CONFIG_HOME
                  ]
                  default "~/.config"
               }
               "/alsa/asoundrc"
            ]
         }
      ]
      errors false
   }
]

And there's also https://wiki.archlinux.org/title/Advanc … chitecture & https://wiki.gentoo.org/wiki/ALSA

All I have ever needed to do is set the default card from HDMI to analogue to get both speaker output and microphone input working with firefox-esr in my Debian systems, as per the link kindly supplied by Camtaf.

What exactly do want ALSA to do? What sort of customisation is required?
