I recently bought a Playbar and from the beginning the volume of music played from the Sonos app seemed about 40% lower than I anticipated (50% volume sounded as I thought it would at 30%).
Also from the beginning, the TV volume (Samsung smart TV through optical audio) seemed exactly how I expected.
Today I explicitly tested my hypothesis listening to music and TV back to back. 50% volume for music sounded fine but somewhat gutless. Switching to the TV immediately resulted in the volume level I expect from 50%.
Thank you in advance for any thoughts or advice.
