HDMI on TV keeps cracking?

I connected my laptop to the TV with a long HDMI cable.

Unfortunately, it cracks again and again, especially when there are dropouts in the sound during playback, eg pauses in speech, etc. Each time it cracks slightly when the pause ends.

A different cable (short, different make) leads to the same error.

According to the device, drivers are up-to-date.

Any tips?

Other cables touching the HDMI cable?

Had the same problem, helped to "disconnect" the cables

Long is how long

so over 5 meters I have gained the experience that problems occur with passive cables. But there are also active systems in which the signal is converted or amplified.

Could even be 7 meters. But with the 1.5 meter cable the problem is unfortunately identical.

Active systems?

Thank you, but unfortunately nothing changes then. In the meantime, the HDMI connection on the laptop has also been checked, but the problem persists via a hub via USB C.

Systems: (with converters) e.g. To transmit HDMI over a LAN cable. Not to be confused with IP transmission, that is also possible.

Tried another HDMI input? Tried another source device?

Tried other HDMI input yes

No other device yet, no second in the household. I will probably have to organize one day
