Hi @TacticalTeacake, welcome to the Sonos community. Thank you for reaching out to us and letting us know about your concern.
Let me help you with this by following the steps below to see if it works for you.
1. Unplug the optical cable from the Sonos Beam and the TV.
2. Unplug the power cable from your TV, the Sonos Beam, and any connected audio source (such as a cable box or video game console). Wait 30 seconds before you plug them back in.
3. Reconnect the optical cable to your TV and the Sonos Beam. Inspect the optical cable to ensure it’s not bent or kinked and check to see that it’s fully inserted into both devices.
4. Update the TV’s software (if available)
5. Check for Sonos update - Settings > System > Check for updates.
Let us know how you get on with the advice above. Please submit a diagnostic report and post here the confirmation number to check your system functionality and to further assist you with this. We'll wait for your reply.
Hi @Rowena B. . I followed the steps above, but still don't notice a whole lot of difference with either the Speech enhancement or night mode function enabled.
I've submitted the diagnostic as requested. Ref 1498666804
