Hi,
in addition to my E-coder, on a secondary remote site, I am using an old fashined usb-232 adapter to connect my paddle to the computer. (see the picture below).
On Linux KUbuntu 20.04 I don't have any audio problems, it works fine. On the Windows computer I had to install the ASIO4ALL driver to overcome a audio latency issue. While you are waiting for the e-coder 2 check if your soundcard has its own ASIO drivers or give a try to ASIO4ALL.
You can find a detailed descritpion of the Ecoder audio issue that danielwee talked about at the following link
