Question

No Sound From My Samsung AllShare Cast Hub - Help Please!

Feb 11, 2015 9:28AM PST

I recently purchased a Samsung AllShare Cast Hub so that I could mirror my Galaxy S3 phone on my Vizio E600i-B3 TV. I hooked up the AllShare Hub through my Vizio S5451w-C2 soundbar. Everything worked great! Later, because I have to share the two soundbar HDMI inputs with my cable box and my Blu-Ray player, I installed a Monoprice 4X1 HDMI Switcher between the soundbar and the AllShare Cast Hub (the Blu-Ray player is also connected to the switcher. Again, everything worked exactly as expected. I could switch flawlessly between mirroring my Galaxy S3 and watching a Blu-Ray. Both audio and video worked perfectly. Today when I switched on the AllShare Hub and tried to mirror my phone, only the video worked. No sound! The Blu-Ray audio/video worked fine when I switched the inputs on the Monoprice switcher. I've since removed the Monoprice switcher and individually connected the Blu-Ray player and the AllShare hub. Still, no audio from the AllShare hub, but the Blu-Ray player works fine. I've confirmed that all inputs/outputs are setup correctly. I've since found several web discussions regarding intermittent audio from the AllShare hub, but found no resolution. Any suggestions would be greatly appreciated!

Sadly true. HDMI chips have this DRM system.

To reset it I have to power down the TV, unplug AC, HDMI cables and wait about 15 minutes. Apply power and the HDMI cable and it usually clears up until it happens again. To me this is a design fault. To its makers it's a security feature.

You may have to remove this from the HDMI switch box.

No Sound from AllShare Hub

Thanks very much for your reply. While it's disappointing to hear that this is a systemic problem, at least I'm glad to know that I'm not the only one who's encountered it. I wonder if it could be fixed by updating the AllShare hub's firmware? In the mean time, thanks for your reset procedure. I'll give it a try.

Try the usual first.

If it clears up, it's the usual. If not, make the call. As to the HDMI issue, the code for HDMI is in the chips. That is, the code can't be fixed. HDMI was a great idea but it's HDCP is not perfect.

I think the AllShare with no sound come with android update. I have trouble with allShare sound when I use my S4 for mirroring but the S4 of my girl work fine with allShare hdmi. I have a monoprice switcher too. The sound and video work great and not mine. The only difference is the android update on mine. She don't want update because they dump face unlock. This 5.0.1 update is not great for me. Good bye allShare. Anyone have idea to fix?

In response to my last post, I am back with the android 4.4.2 and allshare work great with the same settings and devices. The android 5.01 was the trouble.
