hissing and crackling

a B&O with DVD installed; DVD runs great sound no volume problems, no cracking means box is ok for me.

With all TV channels, as soon as the volume is at an audible level, I have a strong hissing and cracking sound?

HDMI cable already replaced, HDMI Anschluss not changed from A to B yet…

thanks for your tips

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.

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

not lost.

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?

Enea, thanks for the query, I got the Swisscombox exchanged, but that didn’t help either.

TV box settings, I don’t know what you mean…

I switch on the B&O TV with the B&O remote control, and I control everything else, including the volume, with the Swisscombox

The B&O TV has a central speaker from where the sound comes (perfect as ever with DVD) with TV hissing and crackling

It doesn’t matter whether the TV is loud and Swisscom is quiet or vice versa, it doesn’t work

The TV has been under repair since today, you can imagine that it’s the HDMI connections and they probably can’t be repaired with normal effort… as of today, not a good outlook…

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

Hello Enea

I remember we tried these settings too; Anyway the problem is the HDMI ports.

I’ll be able to pick up the device today and find out a way to connect it “differently via the Swisscombox” and that works according to the technician. I’m looking forward to another TV evening… and THANK YOU to everyone who supports me with troubleshooting!

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.

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.

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.
