Problem with earbuds with USB cable and Phone Apps

Hello,

This is very strange, with the Fairphone 6, e/OS (Murena), no way to use the earbuds with USB cable with the phone apps!

The earbuds (2 different sets with USB cable or adaptor) are working fine with other apps (as such as Idagio, Music or Audible), no problem at all but with the Phone apps : no sound onlys cracks sometimes…

I am not alone with this stuff, is there anyone who found a solution??? I guess the settings might be a solution but I do not find the parameters to be used…

Thanks for coming back on the stuff!

Kind Regards,

Marc.
