4 Mic Linear Array not recognized

Products & Technology Raspberry Pi
#1

I am little stuck when trying to install the 4 Mic linear array with my raps 3 B+.

I have installed the kernel drivers (seeed-voicecard) and rebooted.

However the mics are not recognized:



arecord -L

null

Discard all samples (playback) or generate zero samples (capture)

default

ac108

dmixer

ac101



Also the snips audio server does not see the device.

arecord -Dac108 -f S32_LE -r 16000 -c 4 a.wav

says: invalid value for card.

Hi there,



It seems the driver is not installed correctly. Please uninstall the driver and install it again. If you still can not get it work, you can download the image 2018-08-06-raspbian-for-respeaker.zip with the driver installed. thanks.

Hi there,



Previously the driver is not compatible with Linux raspberrypi 4.19.42-v7+. We just updated the driver by following below instructions. thanks.

Thanks, that solved the issue.

Hi,

I’ve followed the installation instructions. When I check the record device I get the following:



pi@raspberrypi:~/griefbot/griefbot $ arecord -L

null

Discard all samples (playback) or generate zero samples (capture)

ac108

dmixer

ac101

default

Playback/recording through the PulseAudio sound server

sysdefault:CARD=seeed8micvoicec

seeed-8mic-voicecard,

Default Audio Device

dmix:CARD=seeed8micvoicec,DEV=0

seeed-8mic-voicecard,

Direct sample mixing device

dsnoop:CARD=seeed8micvoicec,DEV=0

seeed-8mic-voicecard,

Direct sample snooping device

hw:CARD=seeed8micvoicec,DEV=0

seeed-8mic-voicecard,

Direct hardware device without any conversions

plughw:CARD=seeed8micvoicec,DEV=0

seeed-8mic-voicecard,

Hardware device with all software conversions



Which is not exactly the same as the list I see on your webpage.



I am able to record and play the a.wav file correctly, but when I try to run my python project (a chatbot) It doesn’t seem to work, I just don’t get an answer. I think there is a problem with ALSA.



When I run my project I get this:



(bot.py:18525): Gtk-CRITICAL **: gtk_widget_get_preferred_width_for_height: assertion ‘height >= 0’ failed

Sorry for all the text. Hope you can help.

Hi David,



The driver is updated and wiki page is not updated yet. We will update the wiki page. Which code you do run and then you face the issue? thanks.

#7

I run a python script, a chatbot to be precise

#8

You blog post is just completely quality and informative. Many new facts and information which I have not heard about before. Keep sharing more blog posts.

#9


What about the wiki alexa demo? Does it work correctly? thanks.
#10

It doesn’t work either :confused:

#11

I’ve followed the instruction, but nothing seems to work. Should I use the raspbian image you posted on this thread? When would the wiki page be updated? I’ve been struggling with this issue for weeks know.

Hi there~,



I follow wiki page and test it well. Can you use the audacity to record the audio files,please? THANKS.

Ok, so I tried this a few times and I’ve noticed that sometimes audacity does not recognize the input device, I need to reinstall the sound card a few times for it to appear. It finally recorded and played in audacity, alexa worked, but after the first use it stops working saying that ssl handshake failed. I reinstalled everything and the input device is recognized by audacity, but I can’t get sound from the speaker jack, but rather from the raspberry pi 3.5 mm jack. When I use aplay and arecord I can’t use it again, since I get a ‘Device or resource busy’ error. Do I have to keep reinstalling the driver until it works? And once it does, would I have to do everything all over again?

#14

Hi there~



For the work around, you can download the 2018.08.06 raspbian for respeaker image. it includes the drivers and avs as well. We are trying to simulate your issue. thanks.



<LINK_TEXT text=“https://v2.fangcloud.com/share/7395fd13 … 13&lang=en”>https://v2.fangcloud.com/share/7395fd138a1cab496fd4792fe5?folder_id=188000207913&lang=en</LINK_TEXT>

#15

I’ll try that. Thanks

#16

I tried the Raspbian image you suggested and it’s the same story. I’ll try to describe my problem, because I get the exact same behavior when I follow the wiki steps. I’ve tried to install the drivers using the 4 mic linear array as well as the circular 6 mic array and no luck so far.

In the following message I’ll copy the entire terminal activity when following the wiki steps. Maybe that’ll give you a better idea of what’s going on.



Best regards



David

Hi there~


  1. If you use above image, you do not need to install the driver. You just need to run the arecord -L. Please also take a picture about your mics FPC cable connection in case the wrong connections as well. You can reboot one more time to check if you can see the sound card.


  2. We tested with latest kernel Linux raspberrypi 4.19.42-v7 and it works as well.

  1. we see some pulse audio issue and update the wiki page for the alexa interaction python scripts. you can check the wiki for the detail info. thanks.
