Double Audio Output

Hi there. Please can you help me.
I have a Foxsat HDR, a Samsung UE40d7000 tv, a Roku Express and a Canton DM50 Sound base.
Everything works fine except...I am not getting Dolby Digital (just PCM) when connecting the Foxsat directly to the TV but get it's fine (and much better sound) when the Foxsat is connected directly to the Canton (via Toslink). However, if I play through the Roku box I get two lots of Audio through the Canton at the same time. It's all set up as follows: - Foxsat to TV is connected via HDMI. Roku box connected to TV also via another HDMI (tv has 4 hdmi's). The TV is connected to the Canton via a Toslink cable (the Canton doesn't have any HDMI connections). As said this setup works fine but doesnt run DD through the TV (just pcm) from the Foxsat. The Roku runs fine in itself with great DD sound. To "cure" this problem I've run the Toslink cable directly from the Canton to the Foxsat and the sound difference is totaly different. But...then if i use the souce (AV) to run the Roku I get two audio channels. One through the Canton ( the foxsat feed), and the other through the TV speakers (the Roku feed). The TV is set to external speakers and makes no difference if I change it to internal speakers. I can get it to work on a single audio channel via the Roku feed by turning the Foxsat off. But this causes the Canton to turn off as well when it sees no signal. I know this is long winded and seems weird but spent hours on settings. The TV is old with limited sound options and the Canton doesnt have hdmi. What are the alternative setup options to 1. Sort the non DD from the Foxsat and 2. Stop 2 audio channels sounding at same time). Any help would be welcomed. Thanks
 
It made my head hurt just reading that. It would be enormously easier to read and try to comprehend if it were broken up into paragraphs. The point of paragraphs is to present the text in easy-to-digest chunks.

I had to google to find out what that is. Turns out to be a sound bar. That means it has its own speakers.

Do you mean stop the sound coming from the TV and the sound bar at the same time? Surely that's easy: set the TV to mute or turn the TV volume down to zero.
 
I have a Firestick playing through an Onkyo receiver and always set the TV volume to zero as the latter two are connected by Toslink, there is no alternative with my set up.

Agree with BH, I struggled with your formatting. A plan drawing would be simpler to describe your set up.

ChatGPT came up with the following re-wording on its first attempt:

Hi there! I could really use your help with my audio setup. Here’s what I have:
  • Foxsat HDR
  • Samsung UE40D7000 TV
  • Roku Express
  • Canton DM50 Sound Base
Everything generally works well, but I’m facing a couple of issues:
  1. Audio Format: When I connect the Foxsat directly to the TV via HDMI, I only get PCM audio instead of Dolby Digital. However, when I connect the Foxsat directly to the Canton using a Toslink cable, I get much better sound with Dolby Digital.
  2. Dual Audio Channels: When I play content through the Roku, I hear two audio streams at once: one through the Canton (from the Foxsat) and another through the TV speakers (from the Roku).

Current Setup:​

  • Foxsat to TV: HDMI
  • Roku to TV: HDMI (the TV has four HDMI ports)
  • TV to Canton: Toslink cable (the Canton doesn’t have HDMI)

Issues:​

  • The Foxsat doesn’t output Dolby Digital when connected to the TV.
  • When using the Roku, I get simultaneous audio from both the Canton and the TV.

Workarounds:​

  • When I connect the Toslink cable directly from the Canton to the Foxsat, the sound quality improves, but then the dual audio issue arises when I switch to the Roku.
  • I can stop the dual audio by turning off the Foxsat, but this also turns off the Canton since it loses the signal.
I know this setup is a bit complicated, and I’ve spent hours trying to find the right settings. Since the TV is older and has limited audio options, and the Canton lacks HDMI ports, I’m looking for alternative setup options to:
  1. Get Dolby Digital from the Foxsat.
  2. Eliminate the dual audio channels when using the Roku.
Any help would be greatly appreciated! Thank you!

Thank you for the time setting out the correct layout and relpies.1st attempt at this.

Ok, turning just the TV sound down or mute does not help as both the Roku and Foxsat is being fed to the Canton. On the Samsung TV, the option for speaker Internal/External is set to External.

There is no individual setup's to adjust this on HDMI2 (the Foxsat) and HDMI3 (the Roku).

Incidentally, the option to set the Toslink on to DD on the TV is greyed out and you can only set PCM. It was like this on the old Sky HD box, I've just never tried to sort this out until now. All the kit is about 14 years old now excluding the Roku. Maybe it is just the limitations of the kit.

Thank you.
 
I can't parse what your actual system setup is, and to be honest the ChatGPT version is an interpretation which may or may not be fact. Neither am I clear where your two cannels of sound ar coming from – on original reading I thought you meant the sound was coming from both the TV and the sound bar.

On second reading I think you mean there are two sources active in the sound bar, but that would not be usual.

Do a sketch, attach it to your post as an image.
 
For the purposes of this, it's just another source outputting HDMI.
I don't know how this guy has things connected either.
The Canton has optical and co-ax digital inputs and analogue phono inputs.
For his workaround, he said he's connected the Foxsat to the Canton, presumably using optical.
He hasn't said how the Roku is connected, but it's embedded audio on the HDMI to the TV. But then what?
Either Co-ax from the TV to the Canton - seems unlikely; or analogue audio from the TV to the Canton - more plausible, but you lose any DD from the Roku.
Either way, if this Canton device is outputting two things at the same time, then it sounds like it's faulty.
It appears to have input selection, and one would assume it is designed to select only one of the three inputs at once.

TBH, it could be anything else as well, as he's not very coherent.

Thank you for the reply.

Yes, it's rather confusing. I have made some enquiries directly to Samsung and will wait for their reply.

Thank you very much for the replies to my query. It is very much appreciated.

I am still awaiting a reply from Samsung.


So...

Ok. Had a reply back from Samsung TS. My UE40d7000 does not support Dolby Digital hence the option being greyed out. So it's NOT a problem with the Foxsat as I thought it might be.

As mentioned, I can bypass this problem by connecting a SPDIF optic cable from the Foxsat directly to the Sound Base. This gives brilliant sound. This is ok if you haven't got another source (Roku). If you play this then you get a double output through the Sound Base. The Roku is connected via HDMI to the TV and output for this is now via analogue Phono from TV to Sound base ( no hdmi inputs on Sound Base). So you can see my problem.

Some of you might just say 'Turn the Foxsat off when using the Roku '
Yes, this does work but when you turn off the Foxsat it automatically turns off the Sound Base and yes auto off options are set to off.

It's time to update a 14 year old system so thanks for all your time and efforts to finding an answer.....signing off!
 
It sounds like the sound bar is the problem. It seems stupid that it should not give priority to one input or another, or perhaps it works on the basis that all inputs are live and you have to control the sources – a cheap option.
 
The thing has an input selector. It's faulty if the selector isn't selecting, as I said before. Perhaps the user hasn't even bothered cycling its inputs to see if that makes any difference. It makes be stuck in a strange mode. Who knows (or cares).
Seems like he has confirmed what I said about the connections though.
