Sonos Arc + PS5 + Linear PCM
There’s been a lot of discussion around this issue but I’ve seen no definitive answer from a Sonos rep so let me try asking based on my personal setup.
I have a Sony PS5 connected to a Sony AG9 OLED via the HDMI 1 port (enhanced). That TV is connected to a Sonos ARC via the HDMI 3 port (eARC, enhanced) with the Sub (gen 3) and x2 One SLs.
The TV sound settings are as follows:
- Speakers: Audio System
- A/V sync: Auto
- eARC mode: Auto
- Digital audio out: Auto 1
- Digital audio out volume: Max
- Dolby Digital Plus output: Dolby Digital Plus
- Pass through mode: Auto
The Arc has successfully output Dolby Digital Plus, DD+ and Atmos in testing with various Android TV streaming apps including Netflix, Prime, Disney+ and Apple TV+. So the TV using it’s built-in apps are performing great. The PS5 however is a different story...
The PS5 settings are as follows:
- HDMI Device Type: AV Amplifier
- Number of Channels: 5.1
- Audio Format: Linear PCM
The Sonos App tells me that the audio in this configuration is Multichannel PCM 5.1 which is correct however the sound is audibly low and to my ears (and judging by the community theirs as well) there appears to be channels compressed/missing.
Now, if I switch the Audio Format to Bitstream (Dolby) the Sonos app tells me that the audio in is Dolby Digital 5.1 which is also correct (and sounds far better than LPCM with audible distinction between channels) however this would mean no DD+ or Atmos for supported Blue-ray discs if I understand correctly.
So the questions:
- What are the best sound settings for the PS5 in this configuration?
- Is there a bug with the LPCM implementation?
- If yes, is it being addressed?
Thanks in advance for any advice.
