Frequently Asked Questions

Sony soundbar power light is on but no audio at all?

Check the selected input first. If correct, verify the TV audio output is set to External Speakers or HDMI ARC — not TV Speaker.

Sony soundbar silent with Netflix or YouTube but works with cable?

Some streaming apps output Dolby Atmos or DTS:X. If the soundbar does not support these formats, set the TV audio output to PCM in TV sound settings.

Sony HT-A3000 or HT-S400 no sound — common fix?

For these models, try disabling HDMI Control on the TV, rebooting both devices, then re-enabling HDMI Control. This forces a clean ARC handshake.
