Hi everyone,
Hoping someone can help me figure this out, because I’m honestly running out of ideas.
I’m writing from Austria, and have been a loyal Sonos customer for years without ever experiencing anything like this.
Currently on my third Arc Ultra (Sonos replaced my original Arc Ultra, and then replaced the replacement unit 🙂) and all three have had the same type of distortion/crackling from one side on higher-pitched sounds, especially piano and certain voices. It is clearly audible from meters away, even at low volume.
The strange part is that the affected side changed:
- Original: left side — serial starts with 2508LC
- Replacement #1: left side — serial starts with 2508LC
- Replacement #2: right side — serial starts with 2507LC
I’ve tested different TVs, Apple TV, AirPlay, Sonos Radio, the Arc Ultra by itself,
Trueplay off, and a complete factory reset/setup. The issue remained.
To be fair, Sonos Support has been very kind and helpful and approved the replacements after seeing my videos. However, I’ve now had to use total of three days of annual leave dealing with the replacement process, and I’m really hoping I don’t have to go through it again.
I’ve also found several reports of similar crackling/fuzzing issues with Arc Ultra on here as well as reddit etc. Should I keep replacing the unit until I “win the lottery”? 😞
At this point, I genuinely don’t know what else to try and would really appreciate any advice.
Thank you!
