Unstability in HDMI-CEC (simplink) and ARC

I bought a 42LW5500 one month ago with a BD660 (blu-ray) and a Denon AVR1611. I activate the HDMI control in the DENON and enable ARC and Simplink on the TV. The speakers works perfectly commuting to the amp when powered and TV selected. But the 8/22/11 there is a software update 04.00.18 since I lost the ARC function and Simplink see nothing on the HDMI network. Today the TV detects another software upgrade I hope a correction for my problem and the first time I test the simplink it detects the TV and a Hard Disk Recorder but not the speakers. I try to switch on the AMP (which was in standby) but after a retry Simplink see nothing. It is the current state.

One other point when I change input on the TV (i.e. HDMI->TV) the amp switch from the current source to TV so the link is working but not has expected.

Doe's anybody have ARC working well with this software version ?

But after installing dozens of optical cables I think the industry has failed again.
