Our sonos playbar all of a sudden stopped playing the TV sound. Still can played over but not TV sound nor DVD nor Apple TV. Please help.

I have same problem. It was working perfectly for 1.5 years but suddenly stopped yesterday. Restart didn't work. Checked all cable connections are secure. Updated software on Sonos and Samsung TV. Diagnostic number 7364937. Please help!
Hi apatt, welcome to the community. I've reviewed your diagnostic. Please back sure the optical cable is fully pushed in on both sides. Also, please check that the TV settings haven't changed.

The cable is fully pushed in on both sides and the TV settings are set to external speaker as they have been for the last 1.5 years. What is the next thing to troubleshoot?

apatt, The next step would be to isolate where the breakdown is happening as the PLAYBAR is not registering there is an optical cable plugged into the PLAYBAR. Can you temporarily disconnect the optical cable from the back of your Samsung TV and plug it directly to a source device like your cable box? When you make the connection check again to see if you hear any audio being output from the PLAYBAR. If you are now hearing audio from the PLAYBAR it would indicate that the TV itself is not outputting a signal through its optical port. Please let us know the results of these steps.

Hello


Sorry to bother but I appear to be having a similar issue. Code 7377664

I've unplugged all devices
Restarted tv
Checked sound setting on TV (pcm )
Optic cable is shining on end going into play bar, but not into tv

Can play music to play bar just fine

Thank you so much for your help

Hi Azzigp,

Thank you for submitting that diagnostic. Can you let us know what media devices you are using (Apple TV, Cable Box, Blu-Ray player, etc.)?

If you have not already done so, please check for firmware updates on your TV as well.

I have same issue: TV LG 49UH7707 (latest software version 04.31.12) connected through original optical cabel to SONOS playbar (latest version 7.2 build 35339010), red light is visible, but there is no sound. Output from TV is set to optical digital sound out with PCM (but I tested all other possibilities like auto). I also tested alternative optical source from CuBox-i with KODI and same behavïour, red light is visible, but there is no sound (I tried many other sound setup). Music playing directly from playbar without any problem, only issue is with optical cabel. Diagnostics 7422198. Thank you for help.

Hello Milos, and welcome.

The diagnostic is reporting that no signal is making it to the PLAYBAR. Would you happen to have another optical cable to test?

Unrelated but still important, there are a few settings on your ASUS router to modify in order for your players to maintain a reliable wifi connection. I'll send you a direct message with the instructions.

Help, im facing the same problem. My diagnostics number is 7440514.

In my case was problem in original optical audio cable. After replacement everything works fine. It is shame that product with this price have problem with cheapest part. Anyway, thank you Nico for your help.

I have replaced the optical cable but to no avail.
