The initial post in the following thread states:
- Please note, we have identified an issue for some users of Arc, Beam and Ray whose configuration includes a Sub (with or without surrounds), who may find their Sub output is lower than desired after performing a new Trueplay tuning.
- Users with Beam or Ray bonded with Sub can increase the Sub level for a more powerful low-end response, however this won’t have the same impact for Arc users. Customers using Arc bonded with a Sub (and/or surrounds) who find their Sub output is lower than desired following performing a new Trueplay tuning, should temporarily disable Trueplay on Arc until this is addressed by an upcoming software update.
- Trueplay tunings for Home Theater configurations without a bonded Sub are unaffected, including standalone soundbars and those bonded with surrounds only.
Therefore, stereo pair setups with Sub are unaffected.
As to the older soundbars, I assume the mention of Arc, Beam and Ray above is based on them being the current available soundbars. If a user experiences any issue with their Playbase/Sub configuration, then I’d follow the same instructions as given for the Beam. If the sub output still seems lower, the next step would be to contact Sonos Support to confirm the status.
