Samsung HW-FM45C 280W Soundbar with Wireless Subwoofer and HDMI Cable Samsung Users Manuals

Sound drops out from the wireless subwoofer. The sound on your wireless subwoofer can drop out if there is interference or a physical obstruction between the soundbar and subwoofer. Make sure the subwoofer is within range of a good signal of your soundbar, and that the issue is not with the source audio.

Smash away. I don't think you can connect a wireless piece to a sound bar. This may be out of my wheelhouse, but I don't think so.

Question about new Samsung HW-F450 setu

Most items don't really have a "reset". Unplug it for 30 seconds. If it's going to work, it will.

Check the speaker of the sub=woofer. If found OK, check and replace the damaged component/s at its audio output section circuit. Contact any service technician. Electro help

yes, hdmi cabels carries audio signals as well as video.

Because your TV is not Bluetooth-enabled and you are trying to connect it to a Bluetooth-enabled soundbar via Bluetooth. There are other ways to connect your TV to the soundbar:

1. analog AUDIO OUT (L/R) of your TV to the AUX IN on the soundbar (use a 3.5 mm.-to-RCA audio cable).
2. Optical OUT on your TV to Optical IN on the soundbar.
3. HDMI port to HDMI port (this may not work if your TV is not ARC compliant you have to try).

You get better sound quality with option 2.or 3. (if this one works for your TV)
