Card display time is decided by card itself. Maybe I can hook the duration, but with some painful effort, not even clearly.
The card itself is hardcoded, so there isn’t enough margin to manipulate. Originally the card would be planned to be used on specific device - smart tv, so ours has some limitation for full usage.
For example, In smart tv, a user can decide to play or not the result of a YouTube search by remote controller, but we haven’t. That is why I implement YouTube player in this module. Other functions are the same. -
@sean Ah I see, its not essential at all! one minor bug I seem to have, that I have noticed does not occur for you in your demonstration video is that now, having finished the audio reply, there is often a very short sound, it sounds like the last half a second of text is repeated, sometimes it is more of a ‘buzz’, I attempted changing the encodingOut setting to one of the other options (MP3 or OPUS_IN_OGG) but both of these just give white noise (like an old tv with no signal) in place of any audio, is this something you have come across at all, and is there anything you can suggest to fix it? maybe getting the alternative encoding to work? thanks

I’m not sure.
Voice output is just buffered stream, so just piping it to the speaker is all of mechanism. So at the moment I have no idea why last data is duplicated(?) in your environment.
Voice output stream comes chunked, so there is some possibility of the time gap between incoming stream chunks.Maybe instead piping Linear16 to speaker directly, writing response stream to mp3(or ogg) file then playing that file could be one of solutions.(sorry, I didn’t implement that)

@jomwells
For the Speaker, research this.

@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.

@sean How to change the piping Linear 16 to ogg. Can I just put ogg in the
encodingOut: “OPUS_IN_OGG”,
-
@sun
No, mp3 and Ogg should be written to file or piping to proper player, frankly I didn’t implement those function, because I thought nobody needs.
I’ll try those till next update. -
Thank you, I will look into piping the audio, but its unlikely I will get very far :)
Question: is it possible to run terminal commands at the different stages of MMM-AssistantMk2, such as running a command to turn on a GPIO pin (using the built in ‘GPIO write X 1’ ) when the module begins listening, and turning it off again when it is understanding, or speaking perhaps? the use case for which would be a status LED on the mirror. Thanks again.

@jomwells
You can fork my repository to yours and modify it.
When you want to relay status to other modules, add .sendNotification() in ’socketNotificationReceived()’ of AssistantMk2.js where proper event is located.
When you want to do something directly, add your job in ’Conversation.on(EVENT)’ of node_helper.js. -

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

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.
