The expectation (or desire) is that it is always active, regardless of the input selected - including HDMI. You'll need a digital input on another device (like your UMC-1) to 'listen' on. Sorry if I am sounding dense on this, but wouldn't plugging into my UMC-1 to "listen" require amps and speakers? I was thinking that I could check the activity of the Digital Out of the XMC-1 by using a Toslink cable that will glow at the other end when it is active. Is the idea to confirm that the output is constantly active or that it is appropriately down mixed? He should get a readout on the UMC display indicating the signal type. But your idea may be just as good if using toslink.

OK, I am awake now. Are you looking to see whether a Toslink cable plugged into the Digital Out on the XMC-1 will be active constantly or only after having set up a given HDMI source to route to Digital Out? Or, maybe something else? I think what he wants to know is simply is there signal at the digital outputs with an HDMI acting as a source and containing audio information. You should not have to configure anything that I know of. Yep, that's what I was thinking. And, here is the answer: The input is DirecTV on HDMI 1 and the little red glow is from the Toslink Digital Out.

Now I have damaged my eye from looking into that red light. Thanks a lot.

Looks great! !! Can you post some pictures of the set up menu?

The red glow you see on a Toslink output is the LASER - which is used to carry the signal. However, just like a radio station may broadcast silence, the fact that you see light doesn't prove that there's AUDIO coming out of it, although they are usually only turned on when they're active. (But, if there is NO light, then that does prove that there's NO signal.) Sorry if I am sounding dense on this, but wouldn't plugging into my UMC-1 to "listen" require amps and speakers?

So does the toslink output the audio of the selected input (regardless of type) just like the analog outs of zone one? (2ch downmixed or pass through if it is 5.1 but obviously not expecting HD audio out) Not sure why it wasn't answered in your response above.

Keith... Isn't your point that the Digital Out is designed to be active for any HDMI source? I understand that the red glow doesn't necessarily mean that the active Digital Out is in fact carrying audio, but, in the case that I have set up where we know that HDMI 1 is outputting audio, wouldn't the lack of audio on this active Toslink cable indicate a hardware problem. In other words, does the red glow indicate that the Digital Out is seeing the HDMI source?

In other words, does the red glow indicate that the Digital Out is seeing the HDMI source? Any functioning toslink output will provide the red glow whenever powered up, regardless of if it is sending a signal. So seeing that red glow does not answer the original question.The question is, when an HDMI source is selected, will a signal be passed through the toslink output. Yes, the output is operational, but is the heart of the XMC-1 passing the audio from the HDMI source to the toslink? Plugging it into a UMC-1 or UMC-200 will show either PCM or DD or No Signal, and that will answer the question. Consider this the digital audio version of "will my AVR pass an s-video input to the composite/component video out" question of yesteryear.

From what I understand, yes, there should always be digital output on the digital outputs when you have an HDMI input. There might be a special "no" case for DSD; I'd have to check on that, but otherwise yes.) The red glow you see on a Toslink output is the LASER - which is used to carry the signal. However, just like a radio station may broadcast silence, the fact that you see light doesn't prove that there's AUDIO coming out of it, although they are usually only turned on when they're active.

Well, now that I understand the question, here is the new apparent answer assuming that the UMC-1 will always reflect the presence of a digital audio input being delivered from the digital audio output of an XMC-1 with An HDMI source selected. If anyone has additional thoughts about steps for this test that they would like me to try, please say so rather quickly as I want to pack the UMC-1 away.

Wow! It looks so nice up against the UMC-1!
Thanks for the pic!

It may be easiest to use a pair of headphones in umc so you wouldn't need to hook up amp/speakers.

What does the display read when the XMC-1 is decoding a Dolby TrueHD 5.1/7.1 or DTS HD MA 5.1/7.1 bitstream with no post processing(dolby IIx movie, etc.)?
