I have a Marshall acton multi-room speaker, it has wifi and Bluetooth, but when I connect to my fire stick 4k, the sound delays for like 2-3 sec. So I tried to create a home theater via the Alexa app, but it can't find the speaker. Does anyone have a solution? I searched on google but found nothing.
Thank you for your comments, if you are having issues with the speaker , please contact firstname.lastname@example.org , they will be able to advise for you.
