No change to sound after Trueplay tuning
Trueplay measures how sound reflects off walls, furnishings and other surfaces in a room, then fine-tunes your Sonos speaker to make sure it sounds great no matter where you've placed it.
If the placement of your Sonos speaker already yields good acoustics, Trueplay will only make subtle adjustments to the sound and you may not notice a difference after tuning your speaker.
If you didn’t notice a difference but would like to further adjust the sound of your Sonos speaker, use the EQ in the Sonos app. You can also compare the sound with and without Trueplay tuning by toggling Trueplay on and off.
