Hi, I have been trying to accomplish Alexa project for about a week now, trying it on Raspberry Pi Zero W, and Raspberry Pi 3, without a real success. I followed your manual, disabled onboard sound card, and everything work except wake word. I can start service by clicking button on java app. Sound otherwise works correctly. I have uploaded my alsa setting on: http://www.alsa-project.org/db/?f=7fd636fe60521a6709d83356a5c03fa401a7ebcb ,and this is terminal output when I try to use alexa avs wakeword terminal shows:

Other problem, when I playing any radio stream or news, I cant stop it only pause it. I can see problem with ALSA, but I dont really know how to solve it
Please can you help me with this.

我在树莓派zero w上面插入4mic 安装4mic驱动，显示安装成功，但是 arecord -L的时候显示

就没有声卡这些信息。像default:CARD=seeed4micvoicec 这些东西，然后录音也没有设备

I am trying on Pi raspbian "stretch" (all up to date) to record with the 4mic respeaker card and following this guide:-

I am running an AVS Java sample app with RPi3 + PiHAT 2mic on Raspian. I have the java client playing a radio, then I try to use the "listen" button to stop the radio, which works fine on a real Amazon Echo. At first I got a Java Exception "can't obtain source audio line error". After that I disabled the mp3 playback function in recordingStarted() in App.js, now the java client app just ignores my voice comment.

My question is: Is the PiHAT 2 mic (HW or SW) capable of recording while playing back an audio?

Hi,

I am running Raspbian Stretch on RPI3. After i installed the drivers and rebooted. i can't see the 4mic array drivers. Below is what i see when i list my audio drivers:

I have installed google assistant sdk previously and that's why you see voice drivers. I don't know what would be the ideal way to reset these drivers with respeaker ones.

here is the status of the seed voice card on my pi when i execute: systemctl status seeed-voicecard.service

Thoughts on how to resolve this issue?

Thanks.

Hi,

As the title says, if i attach the board my Pi Zero W will not boot. Could this be anything other than a hardware fault?

arecord -Dac108 -f S32_LE -r 16000 -c 4 a.wav -d 10
arecord: main:788: audio open error: File or folder doesn't exist

The pixel ring is working with the example files. Only can't seem to get the mic's working on the ReSpeaker 4mic model.

What can I do to fix this?

on a RaspberryPi zero w with an AlexaPi build.
How to trigger the top 3 LEDs of respeaker 2mic hat when Alexa listens and responds?

Hi,
I have a question regarding JST2.0 Speaker Out. Is it possible to connect a raw speaker directly on the Speaker Out terminals? or does it need any audio amplifier to connect with it. What is the output power on this Speaker out..? Is it 1W similar to Respeaker Core or is it different?
Looking forward to hear from you soon.
Regards
Suresh

I am trying transplanting the seeed-voicecard into PYNQ Board ( ARM+FPGA ). When I run make, something wrong shows "scripts/basic/fixdep: 1: scripts/basic/fixdep: Syntax error: "(" unexpected" and its whole log shows below.
What can I do to figure out what causes this bug?

Is there a patch for stretch?

Im on Raspbian Jessie Lite and for the installation of the ac108 driver to work i had to do the following steps:

1. sudo dpkg --configure -a
2. edit the following line in install.sh:
   apt-get -y install raspberrypi-kernel-headers raspberrypi-kernel to apt-get -y --force-yes install raspberrypi-kernel-headers raspberrypi-kernel
3. run sudo ./install.sh 4mic

After rebooting and entering arecord -L I only see PulseAudio. Then when i enter sudo systemctl restart seeed-voicecard i get the voice card to be listed, but it looks like the following:
null Discard all samples (playback) or generate zero samples (capture) pulse PulseAudio Sound Server default Playback/recording through the PulseAudio sound server playback dmixed ac108 multiapps sysdefault:CARD=seeed4micvoicec seeed-4mic-voicecard, Default Audio Device dmix:CARD=seeed4micvoicec,DEV=0 seeed-4mic-voicecard, Direct sample mixing device dsnoop:CARD=seeed4micvoicec,DEV=0 seeed-4mic-voicecard, Direct sample snooping device hw:CARD=seeed4micvoicec,DEV=0 seeed-4mic-voicecard, Direct hardware device without any conversions plughw:CARD=seeed4micvoicec,DEV=0 seeed-4mic-voicecard, Hardware device with all software conversions

When trying to record anything I get the following message:
ALSA lib pcm_direct.c:999:(snd1_pcm_direct_initialize_slave) unable to install hw params
ALSA lib pcm_dsnoop.c:629:(snd_pcm_dsnoop_open) unable to initialize slave
arecord: main:722: audio open error: Invalid argument

How can I bring this to work?

If y'all could cross compile to support Windows IoT Core, that would be great. With Cortana already being built into Windows IoT Core, it would be great to have a mic like this!

Myself and quite a number of others are having issues with this device when using the google assistant SDK.

Audio tests seem to work correctly using the steps in "Configure and test the audio" from the official sdk, however when running the assistant the playback is sped up considerably, to the point where it is unintelligible.

This issue occurs with both the Supplied raspbian image and a manual installation.

Description

I had previously had this working on a Raspberry Pi 3 B however after recently updating via rpi-update the seeed cards no longer appeared. aplay -l only lists the default card, and arecord -l lists nothing.

然后就没有打印了。我重新下载看系统，重新安装都不行，一直阻塞，开始我认为是声卡选择问题，但是我选择正确的还是不行，而且不仅仅是python，我以前写的c版，可以用的，现在也不行了，我怀疑是这般驱动有问题。

Where are the Eagle files located for the respeaker 4 mic array?

My respeaker 4-mic array is working properly and i can output the recorded audio with aplay onto the headphone. But now i would like to use my hifiberry amp+ to output sound.
From the documentation for the amp+ i have to edit /boot/config.txt and do the following:

• remove 'dtparam=audio=on'
• add 'dtoverlay=hifiberry-amp'

Now when i reboot with the changes above, then i cannot find my respeaker wiht arecord -L but see the hifiberry device listest with aplay -L. I then added 'dtoverlay=seeed-4mic-voicecard' to the config.txt with no luck. When i then add 'dtparam=audio=on' again, the respeaker mic is listed again but the hifiberry is not.

Can this somehow be resolved? I really want to output audio with a proper soundcard and not raspberry pi's integrated audio channel.

just wondering if there's a quick/easy way to turn off the white LED on the board that is switched on by default?

hi so I am having a really bad time for a week now trying to integrate pocketsphinx for KWS instead of snowboy(I don't want to use snow boy in my project). and at the same time I also want to do DOA
I have tried to hack and modify the codes in voice-engine. but nothing seems to works for me can anyone please help me in modifying the codes so that I can use KWS(using pocketsphinx) and DOA at the same time

I know there is a library for respeaker as well and it supports pocketsphinx but how can I use it to do both KWS and DOA at the same time with respeaker 4-mics hat with SPI based connection

Its exact the same issue as described in #46, but it fails on Raspberry Zero W with (up2date) raspbian stretch lite.

installation instructions for the 4-mic hat given in the wiki do not match the files in the git.

I have the 4 microphone ReSpeaker board connected to a RPi zero and the microphones seem to be working alright; however, anytime I attempt to use the LEDs the Pi crashes. To use the LEDs I power on GPIO5, which I gather is the "on" switch to start using the APA102s, after which the pi promptly stops responding and restarts. The python script I'm using is:

from gpiozero import LED
led = LED(5)
led.on()

I've read all over the place and don't seem to see anyone else with the same issues. Am I doing something wrong or is my board a lemon?

Thanks!

Hi all ! This is my first post !

I've purchased the ReSpeaker 2-Mics HAT for the Raspberry PI and

would love to use it !

I've followed the instructions on the wiki -

http://wiki.seeedstudio.com/ReSpeaker_2_Mics_Pi_HAT/

but no sound in the headphone port of 2mics hat. i have 3 audio

outputs in my pi. built in audio, HDMI and 2-mics hat. then i

disable builtin sound device via boot config file.

[code]aplay -l && arecord -l

then i copy asound.conf and asound.state files from the source dist

of the re-speaker driver on github and installing them according to

the instructions (put asound.conf in /etc, use alsactl command to

install asound.state)

[code]sudo nano /etc/asound.conf

The IPC key of dmix or dsnoop plugin must be unique

Note: PulseAudio not installed.

Please save my life..

I have installed this driver on raspberry pi (Ubuntu mate 16.04LTS), but I can't use it.

Before installing Pulseaudio I can speak to the google assistant and It recognizes my speech. Using "speaker-test -t wav" I can hear the test sound. But whenever I'm asking something to the Google Assistant I can't hear the response. I can hear the JST connected speaker making a little beep when giving output and the beep disappearing when the response finished. I've tried a few things in Alsamixer but nothing (I tried) improved this.

So then I installed Pulseaudio and ran it in the background (as in the tutorial). The problem now here is I can select only one profile: Output or Input. I want to use both. The JST connected speaker and the microphone on the board. How can I do this?

Raspberry Pi 3 B with the latest Raspbian image. Using the ReSpeaker 2-Mics Pi HAT and I followed this tutorial: http://wiki.seeed.cc/Respeaker_2_Mics_Pi_HAT/

Any help is really appreciated!

Using latest master (b462e8a) with ffmpeg 3.4.2. I can capture with arecord with no issues.

I want to use other OSes rather than raspbian for some reasons. Will that work?

Again @Pillar1989 like i mentioned to you in different streams thank you for trying but the new build command does not build anything.

is this suppose to run on Raspbian stretch with desktop only? I m on Raspbian Jessie lite. DO i need to install a specific version of python maybe?

The install only gets instaled when i execute git clone https://github.com/respeaker/seeed-voicecard.git
with ".git" at the end but then i run into all the other problems i described in the other posts.

I am trying to run a python app that uses a respeaker microphone on RPI3. The app works when i run in on the device but i am not able to access the microphone when i run the app inside a container.

Here is the docker command i use to run the container app:

docker run -i -t myimageid

I am not able to find the device inside the container app, here is a code snippet i am using:

from pyaudio import *
print("=================Looking for sound devices =======================")
p = PyAudio()
for i in range(p.get_device_count()):
    name = p.get_device_info_by_index(i)['name']
    if 'seeed-4mic' in name:
        audio_device_index = i
        print('Using audio input device %d: %s' % (i, name))
        break
    else:
        print(name) 

Is there a way i can access a microphone device in a container app? i read little bit about --device switch but it didn't work.

This is what i tried:

docker run -i -t myimageid --device

我安装驱动后，树莓派没有了声音，即使我在面板下修改成3.5还是不行 raspi-config，只要我卸载了就没问题了，后来我定位是 /etc/asound 删除就可以了，我看安装脚本 是asound_4mic.conf 拷贝进去的，问下如何解决？

Hi, I'm trying to use the 2mic version of Seeed HAT on a Raspberry Pi zero W. I managed to compile the modules on 4.9.59+ kernel over a Raspbian Stretch(the 4.9.77+ does not have headers at the moment, so I freezed it at the stable branch).

The HAT is not recognized in aplay/arecord and I have these errors:

60.592823] gpiomem-bcm2835 20200000.gpiomem: Initialised: Registers at 0x20200000
[ 60.947960] wm8960 1-001a: Failed to issue reset

on dmesg

and

snd_soc_ac108: loading out-of-tree module taints kernel.

before. I expected the latter.

I can't use the HAT in any way.

I tested the same exact configuration on a RPI3 (I swapped the microSDs and mounted the HAT on it) and it's fully working here, LEDs and Google Assistant tested and functioning with audio in and out.

This is the HAT mounting (without the speaker at the moment, to simplify things)

I have no error on compilation and already tried the "./uninstall 4mic ./uninstall 2mic reboot ./install 2mic" procedure with no success.

Tested the dev branch too. Tried to use a Jessie with a 4.9.35+ kernel and a 4.9.59+ too but no joy here. Let me know if you need any log and/or test. Happy to help pinpoint the issue.

Thanks a lot, can't wait to use this product to its full extents.

How can i use this driver in banana pi.

When is there the 2mic board' driver for AndroidThings?

I have installed the linux kernel drivers for my Respeaker 2 mic pHat on my Pi Zero W and can confirm the microphone works perfectly (recorded audio out to file and played it back via a bluetooth speaker). However, when playing audio with the headphones connected to the headphone jack, the audio is barely audible and sounds garbled/muffled.

Does this sound like a hardware issue that may require a replacement Resepeaker 2 mic board?

Command used to test arecord -f cd -Dhw:1 | aplay -Dhw:1

2-mic HAT.
As there are 2 independent controls in alsamixer, one for headphones and one for speaker, how do I find the hp device in order to update alsa asoundrc file to play audio only to headphones?

Hi,

I am running raspbian stretch on RPI3. After installing seeed driver for my respeaker 4 mic array, i am not able to use see seeed mic device because driver issues.

When i execute "arecord -L" in terminal window, i see a stripped version of the expected output with details for installed drivers..etc.

See below:

do you know what i need to do to fix this issue ? so i can see the 4mic array driver as it is supposed to be.

Thanks.

I'm using "Linux raspberrypi 4.9.35-v7+ #1014 SMP Fri Jun 30 14:47:43 BST 2017 armv7l GNU/Linux" in raspberry pi 3. Try the "ReSpeaker_Mic_Array_firmware_xvsm_0x032_20170324.bin" and the factory bin.
I'm using the install.sh script to install the module.
Reboot, and found that

Hi,
Do you know how to install voice card driver on Android things installed in Raspberrypi 3. If its not already available, can you help me in showing some pointer on how it can be written for android things.
Looking forward to hear from you soon.

I have Raspberry Pi 3 B and hooked with respeaker 2-Mics Pi HAT. I use Linux Rasberrypi OS 4.9.59-v7+ built on 10/29/2017. When the system up, "speaker-test -t wav" is OK. I did following to install the 2-mics driver:
$git clone https://github.com/respeaker/seeed-voicecard.git
$cd seeed-voicecard
$sudo ./install.sh 2mic
$reboot
after system reboot, the "speaker-test -t wav" is broken. The test
$ arecord -f cd -Dhw:1 | aplay -Dhw:1
Is broken. No record no playback.
Please help rootcause the issue. It looks like "sudo ./install 2mic" 2mic driver has some issue.

Following the instructions on the wiki, I haven't been able to add support for the ReSpeaker 2Mic because it doesn't compile... The module is never created

Here are the logs when issuing the command: sudo ./install.sh 2mic related to the module building:

For two days I've been trying different versions of Stretch, even jessie, but still no luck...
