Here's the setup. In the kitchen. I have an ipad which I use to watch YouTube TV and music. I have it connected through Bluetooth to an Amazon echo dot. The dot is then connected with a 3.5mm cable to a sonos play5 speaker. Whenever I watch videos there is a slight lag which annoys the hell out of me. Is there a way that I can set this up and not have lag issues and still be able to talk to Alexa and have her talk back through the Sonos?
Make sure both iPad and the Dot on the latest updates. Past that, nothing you can do. Some video players like VLC give you an option to change the audio sync manually, that may work, but will not work for online streaming.
