uboom l doesn't output sound on desktop though bluetooth connected and output selected

Hi friend, 

Thanks for choosing EarFun. Sorry for the inconvenience caused. 

May we know the model of your laptop?

We kindly suggest you upgrade the system of your laptop, reboot your laptop, and then simultaneously press and hold the "Volume +" and "Volume -" buttons for 5 seconds at least to reset and reconnect the speaker. 

We also suggest you try to connect the speaker to other models of devices to test whether it is still the same situation. 

If the above methods still could not solve your issues, please email our customer service team via service@myearfun.com or submit the warranty ticket on our official website: https://www.myearfun.com/process-warranty. EarFun provides an 18-month warranty for every product. Your satisfaction is always greatly important to us.

Sincerely,

EarFun Customer Service Team
