Hey there

I Installed arch new, everything is fine except i don't get any Microphone input.

[harry@harryonarch ~]$ arecord -vvv -f dat /dev/null

I've found similar issues but not yet the solution. Here the outputs which where asked in other threads.

Sorry but I don't find the needle in the hay, reading those outputs.

Do you see any wrong configs?

Thank you

Re: [solved] No Microphone input (internal and external mic)

Your mic is muted:

* index: 3
        name: <alsa_input.pci-0000_00_1b.0.analog-stereo>
        driver: <module-alsa-card.c>
        flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY DYNAMIC_LATENCY
        state: RUNNING
        suspend cause: (none)
        priority: 9039
        volume: front-left: 27904 /  43% / -22.25 dB,   front-right: 27904 /  43% / -22.25 dB
                balance 0.00
        base volume: 6368 /  10% / -60.75 dB
        volume steps: 65537
        muted: yes

do yourself a favor and install and check pavucontrol if you use pulseaudio it would make this immediately apparent. You also shouldn't manually define ALSA hw sinks/sources if it isn't necessary they will only lead to confusion:

pacmd set-source-mute alsa_input.pci-0000_00_1b.0.analog-stereo false

Thanks V1del

that easy.

pavucontrol really helps
