What does the TV-Air have to do with the HDMI cable? Are you watching TV-Air via the PC or which device?

This is the normal TV from Swisscom!

N.b. I have now moved it to the right place.

@scu

Do you have the opportunity to test and plug headphones directly into the TV-Box at the audio output to see whether the sound is OK there?

Which TV-Box do you have according to the link above?

Have you ever switched the TV-Box completely off and on, or if it doesn’t help, reset it?

not lost.

@scu
What audio settings have you made and what settings are currently active on your Swisscom TV-Box?
Which speakers is currently playing the sound?
How or through which tool do you access your speakers?

Hello @scu

Thank you for the more detailed description. Is your B&O TV already back from repairs? If so, does this problem still exist? With my question “What audio settings have you made and what settings are currently active on your Swisscom TV-Box?” I’m referring to the audio settings that you can select for the TV-Box. When the TV-Box plays a station, you can use the Swisscom remote control to click on the Option button and then select one of three tones under “Audio”:

1. Stereo
2. Stereo TruVolume
   3.Surround sound

Kind regards, Enea

At this point I would like to add one more thing:

You can (usually) also switch on the TV with the Swisscom remote control. Then you don’t have to deal with 2 FBs.

Info about it here: [/t5/TV-Wissensbox/TV-Ger%C3%A4t-und-Swisscom-TV-start-with-the-same-remote-control/ta-p/526669](https://commu nity.swisscom.ch/t5/TV-Wissensbox/TV-Ger%C3%A4t-und-Swisscom-TV-mit-same-Fernbedienung-starten/ta-p/526669)

It may be that it doesn’t work with B&O because it’s a rather “exotic” manufacturer, but you can try it

Hello Enea,
I had the same hissing and crackling on the TV, but only on the replay recordings. The TV is an LG CX5, set with AI audio.
Now I have set the sound setting on the Swisscom Box to surround sound and the hissing and crackling are gone.
It happens again with Stereo and Stereo TruVolume.

@UrsSch Can you explain why replay recordings work smoothly with surround sound, while there are annoying noises with TruVolume and stereo?

Hello everyone,

It would be nice if someone who had the error could make a video with sound of the issue.
Unfortunately, I have no idea how the error really manifests itself in the customer.
Ev. It also helps to deactivate the various audio optimizers on the TV and test whether it works better or not.
Unfortunately, I don’t have an LG CX to test it myself… so I can’t really help with that.

At the moment I can’t explain why this effect is like this. But when I have some time, I try to experiment and document it.

Hello,

I have the same problem with the crackling/hissing sound.
It cracks on Stereo and StereoTruVolume, but not on Surround. However, I watch YouTube via the Swisscom Box (2.0) but it still cracks.

does anyone have a solution? TV is a Samsung connected to a JBL soundbar via an optical cable.

@Hameuheik10

Have you tried connecting the optical cable to the JBL soundbar with the Swisscom TV Box instead of the Samsung TV?
This way you can see whether the cracking/noise is really coming from the TV box.
