Microphone not working

Post by Torpus »

Hey Gentooers 8)

I just configured my ALSA and sound seems to be working pretty well on Gentoo, but there's something weird in my microphone which is that after recording something and playing the sample audio, what I actually hear from it isn't my sound or anything, EDIT: Well, actually the recording is completely silent, the speaker DOES play other audios downloaded online etc...

Anyway, this is what I've been doing:

Code: Select all

localhost ~ # arecord --list-devices
**** List of CAPTURE Hardware Devices ****

  Subdevices: 1/1
  Subdevice #0: subdevice #0

         with 8-bit sampling. Use '-f' to increase resolution
         e.g. '-f S16_LE'

See, recording is only 8000Hz, which I guess is pretty low :(

I don't have pulseaudio or anything yet (though I'm planning to use PipeWire)

Thanks in advace 8)

stefan11111,

It's better and less bloated than PulseAudio

I forgot to set the dbus daemon, just turned it on again.

As you can see I already have

Code: Select all

CONFIG_SND_USB_AUDIO=y
CONFIG_SND_USB_AUDIO_MIDI_V2=y
set
