The options you describe don’t even exist in my TV-Box menu. There are: Settings / Video Audio and then Image Quality / UHD Test / HDR / Audio & Sound / Image Quality for Apps. We have/I have already tried everything. Under Audio & Sound you can simply select one of the three sound variants. Of course, stereo is best for me - the others don’t sound as good. Don’t we have the same software? Of course I would have tried resetting everything, but there is nothing with the picture and sound and anything else…

How sound could be heard during the software update is a mystery to me.

In any case, it doesn’t work for me after upgrading to Android and there is no setting anywhere that would change this. Already the second time.

I don’t have the option to reset audio settings. There are no other audio setting options either. Resetting the entire box to factory settings doesn’t help either.

(I think the forum is the wrong place if it works for everyone else…)

@Plickaunne44 If you select the “Audio and Sound” item, you can navigate to the “Reset audio settings” item in the menu at the top right.

Stereo is definitely the right audio mode because you can only output stereo via this output.

If a monitor without speakers is connected to a device (in this case the Swisscom TV-Box) via HDMI, the monitor communicates the information via HDMI that it has no speakers and cannot process audio. To make sure this doesn’t result in the TV-Box not outputting audio, I tested it with a monitor without speakers and it works for me.

I still suggest:

1. Reset audio settings

2. Use the TV-Box remote control to set the volume to the maximum (50/50)

3. Check again with the headphones whether there is no sound

If no sound is output, the following could be checked: Unplug the HDMI cable from the TV-Box, unplug the power cable and plug it back in -> TV-Box should start up without a screen and HDMI -> wait until the box no longer flashes white -> with P+ on the remote control Change the station “blindly” a few times -> check with the headphones whether sound is being emitted. -> If sound is output, the connected monitor is the problem.

Thank you for the elaborate considerations!

Oh there are the audio settings reset; This was placed there at the top right. OK. (Today I’ll look for what else can be selected in the other submenus up there… Maybe something will happen there.

After resetting, the message came: Your settings have been saved. Unfortunately nothing has changed, it hasn’t helped. The sound is missing. No signal at the audio output. I’m familiar with hi-fi, so I don’t think anyone thinks that’s where the mistake is.

Also a good idea to start without HDMI or monitor. - There is no sound. Unfortunately…

Thank you! These are good exercises for Friday evenings and to stay young.

I will then try a reset without HDMI and with HDMI connected but the monitor is not. However, I think it doesn’t help.

And why not watch TV without sound for even a month; almost like a free crash course in lip reading. It’s absolutely amazing what’s going on here; provided it really still works for others after the update. As I said, it is now the second box that no longer works after the update.

@EnSil

Are you having this problem now, if so, probably after an update?

Was the TV-Box already 30sec. Switched off and on (no power)?

Is the TV-Box connected directly to the Internet Box via LAN?

If all else fails, you can perform a reset with a paper clip. In this case, it is important that the TV-Box is connected directly to the Internet box via LAN.

The problem has now been isolated and reproduced. The problem affects installations where the imaging monitor has no audio output options (neither built-in speakers nor an audio out on the monitor). In this case, the box currently refuses to output sound completely.

We are currently working on a fix that will resolve the problem in a future release.

I connected the TV-Box 21 in the basement to a computer screen “AOC” without speakers via HDMI, the speakers are connected to the TV-Box.

For the speakers I use these at the link below and it works.

@WalterB Does your monitor have an audio output? can also just be a headphone output. Then it works. As soon as the audio has no audio options at all, it remains silent. At least that is my level of knowledge of the case.

@RomanE

Yes, it actually has an audio Anschluss on this screen, so the problem doesn’t exist. 😯

It could be that if you connect this part down in front of a monitor without an audio connection in between, the sound will work.

The special thing about the problem is that some people report that it still works. (?!?) Otherwise, I am also convinced that the audio driver was forgotten during the update / does not exist… since the software version was originally made for the latest box without an audio connection… There is already a report of one other users where the audio output on the box no longer works after the update. Technical support hasn’t gotten back to me yet….

Why should there be something special?

Monitor without speakers and without audio output = No sound
Monitor without speakers but with audio output = sound

Roman has clearly written that Swisscom is working on it. Going on about it a dozen more times and making assumptions won’t help.

IT’S NICE IF YOU COULD REPRODUCE THE PROBLEM. SO I WAS ON THE PHONE FOR SEVERAL HOURS ON THE HOTLINE TO EXPLAIN IT. WENT TO THE SWISSCOM SHOP TO GET A NEW BOX BECAUSE NO ONE BELIEVED ME. THE SECOND BOX WAS ALSO THE SAME AFTER THE UPDATE. IT TOOK A LOT IN THE FORUM AND NO ONE HAD THE PROBLEM. MANY SAID IT CAN’T BE. NO ONE BELIEVED ME FOR TWO WEEKS…

IT’S NICE THAT YOU KNOW THIS NOW AND AFTER ALL THAT, I CONCIDENTLY FOUND OUT THROUGH A MA HERE IN THE FORUM THAT I’M RIGHT ABOUT THE PROBLEM. WHAT WAY IS THIS NOT TO GIVE A CUSTOMER WHO HAS THE PROBLEM AND ALSO REPORTED IT AND HAS INVESTED SO MUCH.

WHAT DOES A TECHNICAL PERSON RECEIVE FOR DETECTING THE PROBLEM? SECURE A WAGE…

SO THE PROBLEM EXISTS WITH ALL OLD BOXES AFTER THE UPDATE, MOST NCIHT NOTICE IT BECAUSE THEY DON’T USE THEM WITH SUCH A MONITOR WITHOUT AUDIO. HOWEVER, THERE MAY BE A MAJORITY OF PROBLEMS… FOR EXAMPLE WITH PROJECTS ETC.

IN ANY CASE IT NO LONGER COMPLIES WITH THE SCOPE OF SERVICES AND THE POSSIBILITIES OF THE BOX I HAVE OBTAINED. THIS NO LONGER WORKS BECAUSE OF THE UPDATE.

I’VE BEEN WATCHING TV WITHOUT SOUND FOR A MONTH NOW WITHOUT ANY RESPONSE FROM TECHNICAL SUPPORT AS WAS AGREED. THESE ARE THE PROBLEMS.

IN THE FORUM I SHOULD RECEIVE A DIRECT REPLY FROM SWISSCOM WHEN THE PROBLEM IS DETECTED…
