Hi Henry, 

Thanks for reaching out, welcome to the community. I am sorry to hear that your SoundTouch 300 no longer appears to be producing audio from your TV. 

Do any LED's illuminate on the system when you startup? If so what LED's are lit and what color are they? Are they solid or flashing?

Do you also have any connected bass module or surround speakers with your system? If so, can you please inform us on what added devices you own. 

I look forward to hearing from you. 

Kind regards,

I just had only soundtouch 300 that connect to my tv and both light come on and are solid but no sound from the soundtouch 300 but I can play music from my iphone app. The only system that I connect to the tv are wii, and desktop computer, these systems(wii, desktop) was working before.

Thanks Henry

Hi Henry, 

Thanks for confirming this. 

Can you try resetting the HDMI cable to see if this provides any results? If not, please replace the HDMI cable with a known working cable to test. 

Please also test your SoundTouch 300 with an optical cable connection if this is available with your TV.

Do let us know how you get on. 

Kind regards,

I reset the HDMI but did not work, the HDMI is working because I switch to wii and wii is working and also wii HDMI cable to soundtouch 300 did not work.  I use the optical connector and the soundtouch is working but can not use the Magic TV remote control function to control volume. Thanks Henry

Hi Henry, 

I am very sorry to hear this. 

Are you able to inform me of what LG OLED TV you own?

Has there been any recent change in settings on your TV?

I look forward to hearing from you. 

Kind regards,

Hi Henry, 

Thanks for confirming this. 

What I would next suggest is that you perform a HDMI reset. This can be done by the following instructions;

• -Turn off the soundbar and the TV, then unplug both from power.
• -Leave Both devices unplugged for at least 3 minutes.
• -After 3 minutes, plug the soundbar into power but leave your TV unplugged.
• -Once the soundbar stops pulsing White/blinking Amber, press the TV icon once on your soundbar remote.
• -Now plug your TV into power, turn on and test for audio.

Do let us know if this provides any positive results. 

Kind regards,
