So far as I can tell from looking at the manual online,
your TV does not have any type of audio output connection,
so there is no way to send sound from it to your receiver.
This is a prime example of why people should always check for
the presence of desired connections before purchasing any TV.
If everyone did, and refused to buy any TV that did not have
analog audio output jacks, the manufacturers would have no choice
but to include such jacks on future models.
