Based on our other conversations, it sounds like you are a web developer and are pretty familiar with building Custom Tiles. You could create a tile that allows adjusting the volume using the Fully Kiosk JavaScript API
Fully Kiosk Browser settings → Advanced Web Settings → Enable JavaScript API
For example, here’s a test tile I put together as I was trying to figure out what the right stream was for controlling the volume on my Fire tablet:
You can tap on the volume or channel in the sample tile and it increments each respectively and then plays a TTS message so you can test the volume changed as expected. It should at least give you the bones to get a feel for how things work, but feel free to ask questions.
<script src="https://unpkg.com/vue@next"></script>
<div id="app">
<div v-on:click="incrementVolume">Volume: {{ volume }}</div>
<div v-on:click="incrementChannel">Channel: {{ channel }}</div>
</div>
<script>
const VolumeApp = {
data() {
return {
volume: 20,
channel: 1,
}
},
methods: {
incrementVolume(){
if(this.volume === 100){
this.volume = 0;
return;
}
this.volume = Math.min(this.volume + 10, 100);
this.setVolume(this.volume);
},
setVolume(level){
if(window.fully == null){
alert('Please enable JS API in Fully Kiosk Browser')
return;
}
window.fully.setAudioVolume(this.volume, this.channel)
window.fully.stopTextToSpeech()
window.fully.textToSpeech(`Testing channel ${this.channel} at volume ${this.volume}`);
},
incrementChannel(){
if(this.channel === 10){
this.channel = 0;
return;
}
this.channel = Math.min(this.channel + 1, 10);
this.setVolume(this.volume);
}
},
mounted(){
window.fully.getAudioVolume
}
}
Vue.createApp(VolumeApp).mount('#app')
</script>
<style>
#app {
display: flex;
flex-direction: column;
height: 100%;
justify-content: space-evenly;
}
#app > * {
flex: 1;
padding: 0.5em;
display: flex;
align-items: center;
justify-content: center;
}
html, body { height: 100%; margin: 0;}
</style>
This is what the channels are supposed to be, but only 3 and 8 seemed to adjust the volume as expected on my fire tablet.
