Audio Settings with Respeaker 4 Mic Hat.

[LordTyrion123]

Describe the bug:

Hi @shivasiddharth. Thanks for all the hard work in this project. A quick question though. I'm using a Respeaker 4 Mic Hat as the microphone. The Respeaker is attatched to the GPIO pins of the Raspberry PI 3. I tried both CUSTOM VOICE HAT users and USB DAC or USB Sound CARD users but it doesn't seem to recognize the Respeaker. I tested the installation on a normal USB microphone and it works perfectly. Is there any way to configure it to the Respeaker?

Did you go through or search the issues section to check if your issue was already discussed (either currently open issues or closed issues).

Yes

2. Is the issue related to assistant installation ?

Yes

If answer to question 2 is Yes, then paste the contents of the terminal below.

You need to setup the respeaker device first. Follow their guidelines. Not all audio config files work with all devices, so randomly picking up config for your respeaker will not work. Even after setting up respeaker you might run into issues, if you dont have dsnoop plugin enabled. Follow #466

[LordTyrion123]

@shivasiddharth, I've installed my respeaker and recording works perfectly. Do I now add the dsnoop to the asoundrc and asound.conf?

[LordTyrion123]

@shivasiddharth Everything is working now. Had to add dsnoop to my asound.conf and asoundrc files and it worked like a charm. Thanks for the help!

[shivasiddharth]

I will include Respeaker support in the next update, so that everything gets setup in a single go. Can you share your modified asound.conf file. That will save some time for me.

[shivasiddharth]

@LordTyrion123 Am in the process of incorporating support for respeaker hat. Can you please share the audio config files that you are using.

[LordTyrion123]

Yeah. No problem @shivasiddharth !

asoundrc File

pcm.dsnooper {
    type dsnoop
    ipc_key 816357492
    ipc_key_add_uid 0
    ipc_perm 0666
    slave {
        pcm "hw:0,1"
        channels 1
    }
}

    }
pcm.!default {
        type asym
        playback.pcm {
                type plug
                slave.pcm "hw:0,0"
        }
        capture.pcm {
                type plug
                slave.pcm "dsnooper"
        }
}

asound.conf File

pcm.!default {
    type asym
    playback.pcm {
        type plug
        slave.pcm "hw:ALSA"
    }

    capture.pcm {
    slave.pcm "dsnooper"
    }
}

pcm.dsnooper {
    #type plug
    #slave.pcm "hw:seeed4micvoicec"
    type dsnoop
    ipc_key 816357492
    ipc_key_add_uid 0
    ipc_perm 0666
    slave {
        pcm "hw:seeed4micvoicec"
        channels 4
    }
}

Hope this helps

I have made the Respeaker indicators to work with this project. Give it a shot. Uninstall the previous Respeaker installation and use 3.6 in README.
