[Solved]Mic doesn't show up in Alsa

I'm not sure if this is the right board or should be in laptop issues, feel free to move it to another area if necessary.

I recently got a new laptop (Sony Vaio VPCSC41FM) and the internal mic doesn't show up in alsamixer but mic boost and capture both show up, but don't give me sound on the mic.

There is a patch on the ubuntu bugtracker but I am not sure if it is relevant, as it is posted for a different model laptop. Also, I don't know where to get the Alsa source that I would need for the patch.

Any help is greatly appreciated!

Re: [Solved]Mic doesn't show up in Alsa

  1. Have you checked the wiki's page on Alsa? 

  2. Try

    arecord -l

  3. aplay only shows playback devices: 

    $ aplay -l

I have tried internal microphone not working from the arch wiki using snd_hda_intel instead of snd-hda-intel.

Re: [Solved]Mic doesn't show up in Alsa

Underscores and hyphens are synonymous in module names.

Did you try going into alsamixer, pressing F4 and using spacebar to put a red "CAPTURE" label underneath "Capture" and "Mic"?

Great things come in tar.xz packages.

Re: [Solved]Mic doesn't show up in Alsa

That fixed it. I was confused because I didn't see Mic listed at all in alsamixer, but I needed to turn capture on I guess. Thanks! big_smile
