    Default Internal Microphone not working anymore

    Hi,

    I have an Acer laptop with built-in mic and webcam. I have looked in the internet but can't get me internal mic working in 42.3 with KDE. It worked fine in 42.2 and also in 42.3 for a while.

    Here is my /usr/sbin/alsa-info.sh: https://paste.opensuse.org/86745560

    Many thanks

    Nothing muted? If you don't have installed already, consider using pavucontrol (graphical PulseAudio volume control utility) to adjust as necessary.

    This should show if mic muted...
    Code:
    amixer -D 'hw:0'

    Hi,

    I think that nothing is muted.

    Code:
    amixer -D 'hw:0' | grep Capture
      Capture exclusive group: 0
      Capture channels: Mono
      Mono: Capture [off]
      Capture channels: Front Left - Front Right
    Simple mixer control 'Capture',0
      Capture channels: Front Left - Front Right
      Limits: Capture 0 - 31
      Front Left: Capture 20 [65%] [13.50dB] [on]
      Front Right: Capture 20 [65%] [13.50dB] [on]
      Capture channels: Front Left - Front Right
      Limits: Capture 0 - 120
      Front Left: Capture 60 [50%] [0.00dB]
      Front Right: Capture 60 [50%] [0.00dB]
      Capture exclusive group: 0
      Capture channels: Mono
      Mono: Capture [on]
      Capture channels: Front Left - Front Right
    Also, in the "alsamixer" seems to be fine.

    Level not turned down? Can you run it unfiltered like this?
    Code:
    amixer -D 'hw:0'
    Also, check PA active profile...
    Code:
    pacmd list-cards| egrep "active|output"
    If necessary, you can set graphically with pavucontrol.

    The mic and mic boost levels are turned down.

    Run alsamixer and press F6 to select your system card. Now the actual hardware controls should be exposed. Use the arrow keys to navigate to the mic level, unmute it and adjust the level upwards. If necessary, adjust the mic boost level as well.

    I changed it but still without recording level.

    I can't change that "auto-mute" enabled there.

    Can you not simply toggle it with the 'M' key?
