Installing USB Soundcard using seperate USB Mic

@mrcoffee
give it a try

pcm.!default {
  type asym
  capture.pcm "mic"
  playback.pcm "speaker"
}
pcm.mic {
  type plug
  slave {
    pcm "hw:0,0"
  }
}
pcm.speaker {
  type plug
  slave {
    pcm "hw:0,0"
  }
}

or

pcm.!default {
  type asym
  capture.pcm "mic"
  playback.pcm "speaker"
}
pcm.mic {
  type plug
  slave {
    pcm "hw:0,0"
  }
}
pcm.speaker {
  type plug
  slave {
    pcm "hw:1,0"
  }
}

then restart with sudo /etc/init.d/alsa-utils restart
under alsamixer can still adjust the volume level

@NoNameRo

Thank you for your fast response.
Unfortunately it is still not working. I tried both versions and restarted with the command you told me.
I even rebootet just to be sure.
What I didnt do is switching the cable from jack to the usb soundcard, because it is late and the mirror on the wall again. But I expect, that it would be mute if it works, right?

I forgot to write above, that I can see all 3 devices in the alsamixer.

I have seen solutions to this here: https://raspberrypi.stackexchange.com
search there.

Also, only use ONE sound card for AUX (ouput) and MIC (input). Otherwise you will get confused and so your Pie will be unhappy too. It is also highly recommended to disable the internal broadcom sound card when using a USB card. That you can do in the boot config IIRC.

Now it is getting weired.
I disabled the internal broadcom by adding it to the blacklist:

sudo tee /etc/modprobe.d/blacklist-snd_bcm2835.conf

blacklist snd_bcm2835

After reboot it is correctly not shown again:

aplay -l

**** Liste der Hardware-Geräte (PLAYBACK) ****
Karte 0: Device_1 [USB Audio Device], Gerät 0: USB Audio [USB Audio]
  Sub-Geräte: 1/1
  Sub-Gerät #0: subdevice #0

But if I start playing a media, the sound still comes from the audio jack.
How can that be?

dtparam=audio=off

@e3v3a
Thanks for the help.
I didn´t tried it yet because meanwhile my mic has some problems too. The “beep” from Alexa ist still there but sounds already not round. After that the mic does not react at all.

Guess I will reset the whole system. Unfortunately I did not have a backup.
By the way: If anybody of you knows a raspberry backup programm which I can use under windows please let me know.

I will inform you when I reseted my system.

@MrCoffee I don’t think resetting it is gonna be helpful, unless you know you have installed a bunch of other apt packages, and messed with system settings without writing down what you did.

Try this: https://github.com/shivasiddharth/GassistPi/tree/master/audio-drivers/USB-MIC-JACK/scripts

Hi, I tried the steps from “cloning” to "sudo /home/pi/GassistPi/audio-drivers/USB-MIC-JACK/scripts/usb-mic-onboard-jack.sh " (I have got Alexa not google assistant;-))
The alexa beep sounds normal again, but after that there is silence. And I can still force the beep only once per reboot.

I just tried it. Unfortunately with no luck.
Sound still comes from the audio jack.
