Pi Zero W with USB Souncard and Lav Mic

[maleko]

Hi,

I received a Pi Zero W and the following usb sound card and mic for Christmas:

Soundcard:
https://www.amazon.co.uk/gp/product/B00IRVQ0F8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Mic:

Clip on Microphone, Gyvazla 3.5mm Lavalier Lapel Omnidirectional Condenser...

I am trying to get a standalone instance of Rhasspy working on the Pi Zero W so I followed the instructions in the docs to install via Docker, however I am struggling to get it working successfully.

My first question is, is this possible or can the Zero only be used as a satellite in a master / satellite setup (due to hardware limitations)?

If it is possible to use the Zero as a standalone instance then I need some advice about the setup of the soundcard and mic.

My Setup:
Pi Zero W, with Raspbian Lite and Rhasspy 2.5.8 (installed via Docker)

My Rhasspy Settings:

I am using Send events to Home Assistant.

Questions:

1. In Audio Recording, which device should I select?
   
   

From reading the docs and posts online I know that the working device should have a star beside it or say working! - however the only option that has this is for a null device.

I tried most sensible options (basically every one except those that start “Number Surround Output” but I get no response when I say the wake word (porcupine).

2. This is my log when I start Rhasspy:

It seems like I am having some sort of MQTT error about using port 12183? Although it does seem to successfully connect to the MQTT broker after this error has occurred?

I tried switching to using External MQTT (using my MQTT broker from Home Assistant) however I seem unable to use an External Broker - Rhasspy errors and then locks me out of the web interface. I have to ssh in and edit the profile.json file manually back to default Internal settings to get back online.

I would be really gratetful for any suggestions or advice as to how I can get this working.

Thank you

I think I have the same Lav Mic but a TRS one and not TRRS so don’t need an adapter.

Tiny thing that seems quite good but I pulled off the sponge ‘dead cat’ and clip ring.

Pi Zero is boarderline depending on what you have running with load but many have them running successful.

As a tip to setting up any Pi create a file /etc/modprobe.d/alsa-base.conf

Mine currently is :-

options snd_usb_audio index=0
options snd_aloop index=1 pcm_substreams=2
options snd_bcm2835 index=2
options snd slots=snd-usb-audio,snd-aloop,snd-bcm2835

That will make your usb soundcard be index 0 and just my OCD but makes things cleaner and easier to set up.
You just set up the indexes and the slots will then re-order and yeah it is underscore for indexes and hyphen for slots just to confuse you.
The 2nd device is a loopback as I also use EC but can be omitted.

If you boot your pi with no audio hardware attached.

cat /proc/asound/modules will show you the default state so when you plugin what ever you have you can run again and find out what modules have been added.
/proc/asound/ is where and how alsa accesses and organises audio hardware on linux.

Before you run Rhasspy arecord -Dplughw:0 -r16000 -fS16_LE -c1 test.wav and copy that and play in audacity.
amixer controls
If your soundcard has AGC amixer cset numid=agc 1
You will just have to change agc to the index that control resides on.
alsamixer and f5 to get capture inputs and whack it up to max.

Again arecord test and listen

In fact here I knocked the gain down to -21db on one of those cheap white usb souncards.

Then if I select the voice part of the waveform without the nasty start click and go to effects in Audacity and select amplify it tells me I need 4.8db to normalise to 0db.

So I will up the gain to 25.5db (nearest +4.8db befor clipping) and I have set my mic up to what I expect loudest voice close field 0.3m and the rest is what ever the mic and AGC can provide.

In fact mine is not the same as I got a uni-directional from ebay but was a ‘does size matter’ comparison with my boya. The uni-directional are not a beam just cardinoid with some rear and side rejection that can help with echo and noise rejection that omni’s can not.

Which are the same price https://www.ebay.co.uk/itm/BOYA-BY-MM1-Shotgun-Microphone-3-5mm-TRS-TRRS-Output-For-Smartphone-Camera-DSLR/402621215738?

Prob with shopping can get the 1st mic much cheaper.

I think the Sabrent is a CM108-Chipset

I prefer the Pi3A+ as its only 10$ more but 10x what a Zero can do and for me the $15 vs $25 is a no brainer 10x the Ooomf for 1.66x the price is just such a good deal.

Thanks a lot for the tips @rolyan_trauts
I had no luck getting this mic to work at all with my pi zero. Wasted days on it and then finally gave up in frustration.
I just picked up a pi 4 4gb. Using your steps and some other stuff I found on Google, plus a bit of trial and error, I have managed to get the mic working using arecord in terminal and using PyAudio in Rhasspy 2.5.9 which is great. My intents are recognised and successfully executed as events by Home Assistant.

The one thing that I can’t get to work is my speaker using aplay in Rhasspy.
In terminal I can successfully record a test.wav file in arecord and play it back in aplay, however in my aplay settings in Rhasspy I can not get any sound back out of my speakers no matter which dropdown option I select.

These are my current Rhasspy settings:

I tried every single option in the aplay dropdown but none of them worked:

This is the output from the command cat /proc/asound/modules

0 snd_usb_audio
1 snd_bcm2835

and in raspi-config I made sure to select the index 0 device in my audio settings.

Do you or anyone have any idea where I am going wrong here?

Thanks

This is my basic /etc/asound.conf

pcm.!default {
  type asym
  playback.pcm "play"
  capture.pcm "cap"
}


pcm.play {
  type plug
  slave {
    pcm "plughw:2,0"
  }
}



pcm.cap {
  type plug
  slave {
    pcm "plughw:2,0"
    }
}

But due to my OCD sometime I like to make sure the USB is always the first in the order and always index 0
sudo nano /etc/modprobe.d/alsa-base.conf

options snd_usb_audio index=0
options snd_bcm2835 index=1
options snd slots=snd-usb-audio,snd-bcm2835

A reboot should do that.
Now though we are using docker and that pulseaudio is now installed by default (desktop at least) things can get a bit trickier.

Sometimes I will specify speexrate as its a low load convertor with still good results but you need to install libasound2-plugins and you would think it would work but rhasspy is in an isolated docker container and its only installed on the host so things like that will not work.

What you need to do is connect to the container and install in the container as a seperate asound is also in there.
docker exec -it <container name> /bin/bash is just a a ssh connection but local to your container.

So enter the container and have a look just as you would on the host, if you have anything esoteric make sure its also installed there.
Do a aplay -l or arecord -l and to get pcms its a capital -L

Then the last thing is because of pulse audio as if it is installed it will get sole rights inputs and outputs unless you use the pulse entries in the GUI.
Do a search here for alsa dmix, dnsoop as often examples are posted.

But ignore what anything says on the host connect to the docker container and what does it say in there

If you create a asound.conf the exact same needs to exist in the right place in the container or stop the raspby docker delete and add another share to the initial run command and run again to get it up and running.

docker run -d -p 12101:12101 \
      --name rhasspy \
      --restart unless-stopped \
      -v "$HOME/.config/rhasspy/profiles:/profiles" \
      -v "/etc/localtime:/etc/localtime:ro" \
      --device /dev/snd:/dev/snd \
      rhasspy/rhasspy \
      --user-profiles /profiles \
      --profile en

-v “$HOME/.config/rhasspy/profiles:/profiles”
So host $HOME/.config/rhasspy/profiles is shared and in the container it becomes /profiles
So -v /etc/asound.conf:/etc/asound.conf means its shared and in the same place
