it seems many people is having that issue, and you just archive the threads. it seems all revolves don't work properly with 3.5mm cable. is there any plan to address this issue or give to your customer a serious answer about this failure? if this is a serious problem that can't be solved you should stop selling this item and give to the people affected a proper solution.
Thanks for posting and welcome to the community, that's very strange that the speaker is muting while you are connected via AUX. I completely understand your frustration and I would be more than happy to try to help you out with this! You mentioned that you have seen this issue elsewhere on the community, can you confirm whether you have tried the troubleshooting this thread? If so what was the outcome?
