Installing USB Soundcard using seperate USB Mic

E3V3A

@mrcoffee
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.

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.

MrCoffee

I reinstalled the whole system using another SD-card.
Now I can use the seperate USB-Mic and the audio Out comes from the other USB-Soundcard.
After that I installed all my modules like MMM-Podcast.
I played the video and … sound comes from the audio jack again:-(
However the usb mic and alexa are still working fine. It is just MMM-Podcast which uses the audio jack.
How can that be? I installed the dependecies especially the omxplayer. But that can´t be the reason, or what do you think?

Do you have an idea? Seems like I am almost there.

Thanks.
