Also some do more than others:
Some will only output digital audio from the tuner on the digital out.
Some will output digital audio from digital sources (digital audio in, and hdmi in) but not from analog sources.
Others will digitize the analog audio, and always put some audio out on the digital output.
Some fraction of these may even allow volume control (and /or equalization) of the digital audio before it leaves the TV.
You need to have a specific TV model in mind to really get the answer you're looking for.

Can you generally set the video to output over HDMI, but the audio over optical? I have an older 5.1 receiver which doesn't have HDMI so I am hoping to be able to pass the video signal over HDMI and the audio over optical. Is this typically device dependent or do most devices allow for this?

I can answer your original question for my Sharp LC46DU. The TV is connected to my AVR via optical output. I have a toshiba HD-A2 and PS3 connected to the tv via HDMI. When I have the HD-A2 running the TV outputs 2 channel sound via optical, not DD or DTS. When the PS3 is running nothing is outputted via optical. My normal audio setup is both the A2 and PS3 optical are connected to my AVR. So to summarize tdo not count on the optical output having sound outputted if you are connected via HDMI. Plus it doesnt route DD or DTS so kind of useless anyways. The TV outputs DD properly to my AVR when tuned at a ATSC HD channel.
