How to change audio format Cisco CHS 335HDC?

[Sammy334]

Vizio LED TV works best with L-PCM audio format.

The CISCO CHS 335HDC STB is presently set at AC3.

How can I change that through the diagnostics menue?

I am sorry but currently there is no way to change this using an alternative menu.

Known issue. The only solution is to not use HDMI, connection. Some TVs do have handshake issues. Here is a place to vote for a menu setting to be added in the software and firmware.

Just a Note. I have an older Samsung with a CHS-435, and two different model Vizio sets with CHS-335s and have no issues with HDMI. Perhaps a different cable or use a component cable, with separate audio.

Thanks for the replies Anthony & Prisaz.

I did switch over to a component connection.  However that did not correct the issue.  The Vizio is a recent LED model and appears to have a design or component lot issue since it locks up and the screen goes black and silences the audio but the power stays on.  Then at some point I need to unplug the TV in order to restart the TV.

I'll now go back to Vizio since this unit is under warranty.

Thanks again!

The sound cut off problem is the HDMI handshake issue. It CAN be solved by alwaysturning your TV set on first, then after waiting 10 seconds, the Fios STB. The problem with this is that the sequence must ALWAYS be repeated to avoid thesound cut offs. So if you turn your TV off with the STB still on, you will be back to square one.

You could turn off your STB every tme you don't th TV but the time required to initialize all verizon FIOS channels makes this impractical. Switching to component cables when we've had HDMI for years is not attractive. 

That the CISCO DVRs do NOT have theability to set thesound to L-PCM is another obstacle, and it is bewildering that Verizon FIOS has not addressed this simple solution.
