Raspberry Pi is not recording from USB Microphone

Question

I've an USB hub (Plugabble) with a usb Daffodil sound card. The Speakers are working great, but the microphone is not working. I don't know what to do anymore to get it working. The usb sound card is set as default The arecord command records but no sound is recorded. The aplay play sounds nicely. Here are some of my settings: ``` pi@raspberrypi ~ $ arecord -L null Discard all samples (playback) or generate zero samples (capture) default:CARD=Set C-Media USB Headphone Set, USB Audio Default Audio Device sysdefault:CARD=Set C-Media USB Headphone Set, USB Audio Default Audio Device front:CARD=Set,DEV=0 C-Media USB Headphone Set, USB Audio Front speakers surround40:CARD=Set,DEV=0 C-Media USB Headphone Set, USB Audio 4.0 Surround output to Front and Rear speakers surround41:CARD=Set,DEV=0 C-Media USB Headphone Set, USB Audio 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=Set,DEV=0 C-Media USB Headphone Set, USB Audio 5.0 Surround output to Front, Center and Rear…

Accepted Answer

This depends on you distribution, since different distributions handle the devices differently.

So i think you are running a raspian jessy but tried to configure it like you where on a wheezy.

So if I am right you should go into the file `alsa.conf` with the command `sudo nano /usr/share/alsa/alsa.conf` and edit the lines

```
 defaults.ctl.card 0
 defaults.pcm.card 0 
```

to

```
 defaults.ctl.card 1
 defaults.pcm.card 1
```

then go to the file `.asoundrc` with the command `sudo nano /home/pi/.asoundrc` and edit it so it looks like following:

```
pcm.!default {
    type hw
    card 1
}

ctl.!default {
    type hw
    card 1
}
```

do an reboot and hopefully it will work.

If i was wrong with my guess please comment under the answer and i will update it :) hope it helped.
