It would be too bad if you RMA'd the box and had the same problems with its replacement. It sounds like you are saying you had both sound and picture through the HDMI cable attachment directly to your TV at least one time, but now you only get video but no audio? HDMI is flaky anyways with the handshaking issues between connected devices, the HDMI cable, and the HDTV. All three have to play nice together, and often do not.
Do you have another HDTV with HDMI inputs to which to try attaching the Roku box?
If your HDTV has HDMI inputs, it almost certainly has both component and composite video inputs, both of which use the HDTV inputs' corresponding analog audio (RCA red, white) jacks to deliver sound through the HDTV's internal speakers. Most HDTVs do not have the option to deliver picture through a HDMI input and sound simultaneously through a component or composite input's analog audio jacks because that would require two HDTV inputs to be active at the same time.
What happens when you use one of the composite inputs on your HDTV with the composite cable supplied with the Roku (RCA yellow for video, RCA red, white for analog sound)? Do you get both sound and picture? That would show that the Roku's analog sound outputs are functioning, which are the same ones to deliver sound to one of your HDTV's component inputs.
Do you have a set of component cables to attach from the Roku to your HDTV to see if you get both sound and picture that way? Many people will say that the picture quality of component attachment is the same as with a HDMI attachment- it certainly is on my two HDTVs.
