Hello all,
The following problem: I bought a refurbished Playbar via the Sonos Store and set it up in the living room with 2 Sonos One (Gen 1) as surrounds. Everything has worked so far.
However, as soon as I watch normal TV or a movie in Dolby Digital 2.0 or 5.1, I clearly hear sound dropouts/ stuttering in both Surround Ones. The Sonos App shows Dolby Digital 2.0 or 5.1. With normal stereo sound (stereo PCM,) the problem doesn't exist.
The following settings/connections:
Router: FritzBox 6590 cable
Playbar is the only component connected to LAN via cable.
All players show WM:0
The Playbar also shows OTP:
Sonos Net channel: 6
WLAN 2.4 GHz runs on channel 1 (not Auto)
WLAN 5 GHz runs on channel 40 (not Auto)
All components have fixed IP addresses
TV is a LG OLED65BX9
Connection: Playbar directly via optical cable to the TV
OLED TV settings: Audio output is set to optical, and digital audio output: "pass-through" (bitstream).
The problem only exists when the audio output ("Digital Audio Output" setting) on my TV is set to "pass-through". When I set the output on my TV to "PCM" (then the Sonos app says "Stereo PCM") everything runs smoothly, with no sound dropouts/ stuttering.
I watch TV via a Panasonic UBC70 recorder. There, the audio inputs/outputs are also set to "Bitstream". If I set "Stereo PCM" on the Panasonic recorder and set the TV to "pass-through", then there are no dropouts (the app shows Stereo PCM here as well).
The Playbar obviously has a problem processing the incoming and outgoing TV signal when everything is set to bitstream/passthrough (that would be Dolby Digital 2.0 on TV, for example).
What I can rule out:
- Optical cable defect: previously I ran a Playbase in the same network with Ones as surround. There were no sound dropouts at all. The Playbase is now in the neighboring room.
- WLAN interference: There were no problems with the Playbase
- One defect: see above. Everything worked with the Playbase
What can be the problem, what can I do?
Thank you very much!
