I couldn't find a hardware device. You don't have a valid microphone

[Dani3lSun]

During the installation process, exactly when asking "Do you want to set up and check the speech recognition options?" I get the error message "I couldn't find a hardware device. You don't have a valid microphone" and the installer closes. I have an USB sound card plugged in (for headphone and microphone), and the hardware seems to work correctly. card number is 0.

Take a record:
Command: arecord -D plughw:0,0 -f cd test.wav
Works perfectly.

Play the recorded wav-file:
Command: aplay test.wav
Works also.

Config Files:
/etc/modprobe.d/alsa-base.conf
I edited it to
options snd-usb-audio index=0

/etc/asound.conf
I added this:
pcm.!default {
type plug
slave {
pcm "hw:0,0"
}
}
ctl.!default {
type hw
card 0
}

So I think that my audio input and output configured correctly...What else can be the mistake?
Thanks for your help!

In voicecommand.cpp I look for the word "card" and the word "device":
fscanf(cmd, "%d:",&card);
You don't have that because it's in a different language.
So just edit the config file manually. You can do this by running voicecommand -e
Then you can add your hardware information manually with a line like this one:
!hardware==plughw:0,0

Thanks, that helped. All is working now.

Hi Steven ,
I have a little bit the same problem like highlite86.
I have pluged in a soundcard too and it still not working.

Take and play a record works fine.
I don't edit my config files to 0 because the card is card 1

/etc/modprobe.d/alsa-base.conf

Keep snd-usb-audio from beeing loaded as first soundcard

options snd-usb-audio index=1
/etc/asound.conf
cm.!default {
type plug
slave {
pcm "hw:1,0"
}
}
ctl.!default {
type hw
card 1
}
voicommand -e
#This is the default config file
#These are the special options you can set (remove the #)
#!verify==1
#!keyword==pi
#!thresh==0.7
#!continuous==1
#!response==Yes Sir?
#!quiet==0
#!ignore==0
#!filler==0
#!duration==2
#!com_dur==3
#!hardware==plughw:1,0
#Here are the commands

But it's still not working when i want to test the speech recognition.
I hope you can help me.
