Cant get 4-mic hat to record

Closed this issue a year ago · 7 comments

Hello @HinTak I appreacite you taking the time to continue development on seed devices. I have been scouring the web for the past week trying to get my 4-mic hat array working on the bullseye rasp OS, Ive tried both 32 and 64 bit versions, I finally decided to stick with the 32 bit hoping for better compatibility but to now avail. I am using your repo now and although the system does recognize the drivers I cant for the life of me find a proper command to get it to record any audio.

I even tried to pump data into chatgpt since it is aware of respeaker and its products it claims but that gpt is becoming dumber and dumber by the day it seems.
Here are a few details to my setup:
arecord -L gives me

I noticed when I try to run a simple arecord command i get a Channels count non available
I did learn that when i use 6 channels the command get a bit farther

chatgpt suggested i create a .asoundrc file with this for its contents

pcm.!default {
    type asym
    playback.pcm "speaker"
    capture.pcm "dmixer"
}

pcm.speaker {
    type plug
    slave.pcm "hw:CARD=Headphones,DEV=0"
}

pcm.dmixer {
    type dmix
    ipc_key 1024
    slave {
        pcm "hw:CARD=ArrayUAC10,DEV=0"
        period_time 0
        period_size 1024
        buffer_size 8192
        rate 16000
    }
    bindings {
        0 0
        1 1
    }
}

ctl.dmixer {
    type hw
    card ArrayUAC10
}

pcm.array {
    type plug
    slave.pcm "hw:CARD=ArrayUAC10,DEV=0"
}

Ive tried to install audacity as one forum reply suggested but even then it can see the respeaker device in the dropdowns but when i hit the record button it goes from "stopped" to quickly record immediately back to stopped. I am stumped and ready to toss this thing in the trash im getting so frustrated trying to get it working on this PI. when I first got the device i plugged it into my windows machine and it works great. so I know the device works.

any tips or help would be most appreciated

oh i also had gpt help make me a script to check audio devices using pyaudio:

import pyaudio
import wave


def record_audio(device_index, file_path, duration=5):
    p = pyaudio.PyAudio()

    try:
        stream = p.open(
            format=pyaudio.paInt16,
            channels=4,  # Adjust channels based on the number of microphones
            rate=16000,  # Adjust rate based on the max sample rate
            input=True,
            input_device_index=device_index,
            frames_per_buffer=1024,
        )

        print("Recording...")
        frames = []
        for i in range(0, int(16000 / 1024 * duration)):
            data = stream.read(1024)
            frames.append(data)

        print("Recording done.")
        stream.stop_stream()
        stream.close()

        wf = wave.open(file_path, "wb")
        wf.setnchannels(4)  # Adjust channels based on the number of microphones
        wf.setsampwidth(pyaudio.PyAudio().get_sample_size(pyaudio.paInt16))
        wf.setframerate(16000)  # Adjust rate based on the max sample rate
        wf.writeframes(b"".join(frames))
        wf.close()

    finally:
        p.terminate()


if __name__ == "__main__":
    # Set the index of your ReSpeaker 4-Mic Array
    respeaker_index = 2  # Adjust this based on the correct index for your device

    # Record audio and save to a file
    record_audio(respeaker_index, "test.wav")

but it spits out a bunch of garble i dont really understand and when entere into gpt it thinks im trying to forge id numbers or some stupid response it gave me lol

Have you seen or come across any of this or am I cursed? lol :(

Wrong driver - why do you have a USB audio driver installed? The 4-mic device in this repo is connected via the 40-pin hat. There are two 4-mic devices supported by this driver - a linear shape one and a square looking one, both mounted on top on the pi via the 40-pin hat. There is a picture of at least one of them if not both in the front.

Answer 2 · 2023-12-05T14:16:37.000Z

There is a picture in the front with both of them. If your device looks like one of those, you have installed the wrong software, not the code here, and you should follow the install procedure here. If your device does not look like one of those, then you have simply come to the wrong place, and you should go where you got your device and your software from, and seek help there.

Answer 3 · 2023-12-05T14:27:26.000Z

Hey hintak, thanks for your quick reply. I assumed the board 4-mic hat was the same as their consumer sold 4-mic hat just in a case
i am using the 4-mic hat array they put into a single device https://wiki.seeedstudio.com/ReSpeaker-USB-Mic-Array/
i didnt think they would use different drivers for the same board wrapped in a case.

Answer 4 · 2023-12-05T14:47:57.000Z

Told you already - different device, different driver. If you don't believe my word, what else can I say? Half (really, more than half) of the driver code is about connectivity. USB connection is definitely not 40-pin hat.

Answer 5 · 2023-12-05T14:49:51.000Z

And it is not even the same device wrapped in a different case/connection. Did you even look at the picture at the front and compare?

Answer 6 · 2023-12-05T15:05:35.000Z

holy dude, relax,
respeaker sells a 4-mic hat array dev board and a 4-mic hat array in a case using usb. I was led to the respeaker github https://github.com/respeaker/seeed-voicecard which led me to your repo as an updated version to use since respeaker quit supporting their product. My mistake and sorry to question your superiority over all things respeaker.

my mistake for not being a linux coding guru like yourself and trying to learn new things. I bow down to your intellect. Sorry to have wasted your time.

Answer 7 · 2023-12-05T15:55:55.000Z

I'll repeat your own url for you https://wiki.seeedstudio.com/ReSpeaker-USB-Mic-Array/ - thar uses linux's generic USB audio driver, not the code here. Hardware-wise , that has a XVF-3000. The 4-mics devices here uses either one ac108 or a pair of ac108 plus a ac101. Please go away. You are in the wrong place. And, I don't work for seeedstudio.
