Why don’t I hear sound through my playbar when I have my cable playing through the TV? Since my Samsung flatscreen tv is a little older without a Digital Audio Optical port, I had to buy a Digital Optical to RCA converter to utilize the Red-White ports on my TV. However, I still do not hear sound. Everything is plugged in. Has anyone run into an issue like this before? Thanks

    No, I was looking for a link to the " Digital Optical to RCA converter " that you're using. Mostly because I think it's backwards. You want an analog to digital device, not a digital to analog (RCA).

    Those red and white RCA outputs on your TV are analog, you'd want to be taking the analog signal, and converting it to digital (optical) which would then feed the PLAYBAR.

    And in all honesty, if I was you, I'd be pulling the audio out before it reached the TV, not after. Using an HDMI switch with an optical output on it, something along the lines of

    That way, you would be getting the full Dolby Digital signal going to your PLAYBAR, rather than the stereo signal that the TV is processing.

    Hi Bruce! Hope you’re well. 
     

    so the adapter has been working great, thanks for your help. However recently, I started hearing crackling noises in the sound bar. Any idea why? Do most sound bars do warranties? I received the speaker as a gift from my girlfriend, and we got the speaker in December. 
     

    thanks!

    Usually, when there is a crackle, it’s due to a problem before the signal reaches the soundbar. However, there’s also a slight chance that there may be a hardware issue, albeit extremely small. 

    You probably want to check with the location that your girlfriend purchased the soundbar, if you’re looking at a return/swap. Failing that, you could contact Sonos Support directly to discuss it. 

    However, I would also recommend that you submit a system diagnostic within 10 minutes of experiencing this crackling issue, and either post the number here, or contact Sonos Support to discuss it.

    I usually suggest the phone folks, they have more tools available, but are only available Monday through Friday during business hours. Both the Twitter and Facebook support folks are available 24/7.

    There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
