It's not working like that the signal from the application is transmitted as digital to the USB C / Lightning port (depending of the phone used) (with a software intervention in the case of Android to downsample or upsample to 16/48 if signal higher or lower then that but this functioning should change with Android 14 if streaming apps integrate a specific API to support bit perfect). The conversion is made from the digital signal through the port where the dongle is connected to Bluetooth (conversion to the better codec available) and on the reception side (AKA the headphones or earphones) from bluetooth (codec) to analogic signal then sent directly to the driver(s) if the bluetooth chip as enough output or to an amplification and then to the driver(s). In some cases you can also have a dac on the reception side between the bluetooth chip and the driver(s) (example FiiO FW5). So in a way we should call the BT chips DBC on sender side and BAC or BDC (depending on the configuration) on receiver side.Hello everyone. Could someone please tell me if a BT 11 Qualcomm chip is also a DAC? Or if the music runs through the smartphone's DAC? Many thanks in advance. Kind regards, Bernd
