Hello everyone!
I am experiencing sound crackling on my TV - UE55TU7172UXXH. The sound output is via toslink cable to my amp. The sound starts to crackle after 2-5 minutes after startup (both devices simultaneously) and crackles for few times (5-10x) and then the sound is perfectly fine.
At the beginning I had that common issue of crackling - changing audio output to PCM solved it.
I've been trying to figure this with several methods.
- Changed the optical cable
- Factory settings on TV
The idea of invalid amp also came to my mind. Other inputs on AMP work perfectly fine however the optical could be defective. I've tried the
- DAC transmitter
- TV -->> optical cable -->> Transmitter -->> RCA cable -->> AMP (RCA input)
- Sound crackles
- HDMI Switcher with audio separation
- PC -->> HDMI cable -->> HDMI Switcher -->> optical cable -->> AMP (optical input)
- Sound does not crackle
I've also noticed that sound does not crackle in this scenario: Turn on the TV -->> Wait 5-10 minutes -->> Turn on the AMP
My conclusion is that TV sends some weird mishmashed signal after turning it on.
Appreciate every advice.
