Since you have the cable connected to the reciever thru the HDMI, you may have accidently changed the input source of the reciever from HDMI or digital to analog.
When you have the reciever set to listen to the cable, check the input mode and make sure it is set to use the HDMI or digital input and not the analog.
The rca jacks are analog, and they worked, so I think you have just solved your own problem without realizing it.
Let me know if this works and if so a good rating would be appreciated. Thanks and have a great day
