1. What else do I need to do for install for mmm-assistantmk2 to play youtube.

2. I try the same command say Celine Dion The power of love. Then pop up below detail about Celine Dion and the youtube video automatically pop up but cannot play anything.

3. My magic mirror is vertical mode, rotate = 1 . I try to adjust from your height 480 width 854 of display but it also show in vertical mode height 480 with 640 also height 640 width 480. No different.

@sean How to change the piping Linear 16 to ogg. Can I just put ogg in the

encodingOut: “OPUS_IN_OGG”,

@jomwells Mine is a little bit different as I use the hdmi on tv as speaker as well. the default device fall on card 0 with alsa. For microphone is usb on card 1. I don’t have problem with microphone but I did have problem with sound via hdmi. Sometime sound just come out right through the hdmi but with lag sound, sometime no sound at all and say device busy. Also, to avoid hdmi device busy, I use usb sound card instead of hdmi sound also very lag.

pcm.!default {
type asym
playback.pcm
{
type hw
card 0
device 1
}
capture.pcm
{
type hw
card 1
device 0
}
}

@sean Thank you so much.

@sean I would like to know more about MMM-Gaction regarding the deviceModelId - this should be done since register the device in mmm-assistantmk2. What about deviceInstanceId, where and how to?

@jomwells Are you using rp3 as magic mirror? I did get sound respond now and it really ugly. I do try both sound on tv via hdmi and from usb sound card. Assume that too much modules from magic mirror load.

Got it done. Very nice. However, the sound is so lag. Might be because I run on rp3 and quite many modules in magic mirror.

Not yet install mmm-notificationtrigger.
Do I have to install mmm-notificationtrigger as well?
I manage to get
[HOTWORD] << smart mirror >> is detected.
[HOTWORD] stop listening

but when I say something. it won’t detect what I said. Only detect the hotword.

Install mmm-hotword everything went fine during installation and load magic mirror normally. But no hotword detected.

also show in command promt.

Finally, Got the microphone icon in my mirror. Didn’t detect the voice yet I still have to install mmm-hotword.
But I can ask one question by click the microphone icon and see the pop-up.

I use hdmi on my tv as well. Still no sound.

I will install mmm-hotword and test.

Also the mmm-gaction if it make the mirror better.

I will keep you update and might need your help if I got struck in some part.

Thank you very much Mr.Sean.
