Bluetooth to stereo synced speakers via snapcast would be cool.

[StuartIanNaylor]

I say would be as I have snapcast setup with the default pipe that is working with this asound.conf

pcm.!default {
    type asym
    playback.pcm "plugslave"
    capture.pcm "plughw:1"
}

ctl.!default {
    type hw
    card 1
}

pcm.plugslave {
    type plug
    slave.pcm rate48000Hz
}

pcm.rate48000Hz {
    type rate
    slave {
        pcm writeFile # Direct to the plugin which will write to a file
        format S16_LE
        rate 48000
    }
}

pcm.writeFile {
    type file
    slave.pcm null
    file "/tmp/snapfifobt"
    format "raw"
}

/etc/snapserver.conf is using it as a source
source = pipe:///tmp/snapfifobt?name=BlueTooth

Because its a fifo file it lacks a mixer, but dmix can only use hardware slaves...

Any ideas as x2 L/R stereo snapcast speakers would be cool if it worked :)

I am sorry, this is beyond the scope of this little project, I do not have any experience with Snapcast...
