Hello,
I purchased a Sonos Beam Gen2 with 2x ONE SL two weeks ago.
The Beam is connected to my LG C1 via HDMI earc, with earc enable and passthrough + bitstream set.
Everything was working fine until a few days ago, I noticed some random audio cuts when using the PS5 (1 or 2 per hour).
I have set the following settings on the PS5: AC receiver, 5.1 and PCM. I spent all the week trying to figure out a solution:
- Disconnect and reconnect all devices one by one (LG, PS5, Beam etc.)
- Connect ONE SL via ethernet to my router
- Switch the HDMI port of the PS5
For the record, I use the HDMI cables that came with Sonos Beam and the PS5.
After all this testing, I noticed:
- I had no sound on the PS5 with the PCM 5.1 signal: I had to switch to 7.1 or Dolby/DTS to get sound again, or I had to restart my TV.
- The audio cuts now occur every 30 seconds on the PS5.
I decided to reset my LG C1 and reconfigure everything, since:
- I no longer have these cuts every 30 seconds on the PS5 but I haven't played a long session to confirm that they are completely gone.
- I still have the problem on the Nintendo Switch, audio cuts every 30 seconds in surround mode (PCM 5.1).
I contacted Sonos support who were not very helpful, they said it was probably an issue with the LG C1 firmware and asked me to contact them.
I have no issue when watching movies/youtube no matter what signal I use (dolby atmos, dolby digital, dts, stero), it seems to be exclusively with PCM 5.1.
Do you have any ideas or suggestions?
Thanks a lot,
