Assuming you've booted with the additional /boot/config.txt line(s) suggested by WaveShare, do you see any useful diagnostic messages in the system log /var/log/syslog? Especially warning or error messages?

Using this information I can test my W2 adapter using aplay and a WAV file [1].
I don't know what to expect for your carrier board but WaveShare should be able to tell you.

And the test itself:
et voila, I hear the "this is my voice..." test from the wireless headphones paired and connected to the W2 adapter.
