Question

Playbar optical input poor quality sound


Badge

The sound output on some channels keeps dropping/poor quality - Sky main event on BT sport is the worst!. The cable no longer held in sonos playbar firmly. Changing cable makes no difference. 

Is this a known fault ? Seems that the physical input has failed. Works on wifi ok.

Hi @pjf749, thanks for the quick update. If this issue only happens on specific or certain channels and not on all, it may be the channel itself. But to check on this further. If it’s on the channels or the outlet for the optical cable. Kindly contact our phone support team so they can check further and give options on this issue.

But the sound is fine through the tv sound system - so are you saying its a broadband issue?

Hi @pjf749, thanks for the update and for sending a diagnostic report. As I check the information, it shows that the Toslink or the optical cable is inactive. Kindly try to unplug it for 1 minute and also check the covering and replug it back in. If this won’t still work, then we need to take this further.

No plastic cover - its the same cable that has been used for several years. Tried new cable but returned as made no difference

Make sure you removed the plastic protective tip from the end of the fiber optic, that would prevent the plug from firmly fitting into the Playbar (or TV).

This issue started a few weeks ago - on one channel only - Sky Sports - occurred with the “crowd” noise added to football matched with no crowd. I then thought it was the sound transmission at that time. Was worse on HD version of the channel.

Recently changed tv, and mounted playbar on the wall. Optical input then coming into the top of the unit. The cable doesn't “clip” in - its loose. Bad sound now on more channels. Has got to the point using TV sound for films etc. WiFi music  all ok . 

Careful manipulation of the cable can improve sound but will drop in and out. A new cable has the same issue. 

Do you want photo of the input? 

 

Regards
