Sometimes I need to resort to a CEC blocker, but it’s unknown if this might restrict ultimate bandwidth too much. Fortunately, we are not dealing ultimate gamers or 8K.

Blocking CEC can also defeat ARC- I needed to make ARC work with a Samsung TV & Yamaha Aventage AVR and neither had a setting called 'ARC' but they both needed CEC enabled in order for ARC to work. I don't mind using CEC if the TV is connected to a cable/sat box, streaming box or any kind of basic system but I have seen some crappy performance when in a more complex setup.

I stand by my alternate acronym for HDMI.

With previous versions of HDMI to use ARC, CEC needs to be on. ARC will not work if CEC is off. CEC can also cause problems with turning on/off equipment and switching inputs. The more devices you have connected the more likely it will mess something up.

The new version of HDMI (2.1) will allow eARC to work with CEC turned off to solve some of the input switching and power problems. However, not all devices have that option in their menus to turn off CEC but leave eARC on. It is up to the manufacturer/device whether they require CEC to be on for eARC to work.

For eARC to work all devices need to be capable of eARC and that includes the HDMI extender. That's why if a device has the option to turn of eARC but still use regular ARC with CEC turned on, it may fix your problems with the extender.

HDMI is a messed-up standard!

After no success with a Snap B260 extender on one job, I put in an AVProExpress HDMI extender with ARC and have gotten 3+ trouble free weeks out of it. No more sound flipping from TV to Sonos AMP.

it’s a lot pricier than the Snap piece, but since it works…
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.

Same experience. We have had a lot of SNAP extenders fail, typically it has been the power supply and Snap has been good about replacing them. So, I have to give kudos to Snap's service. However, we'd rather not have problems in the first place, so we switched to the AVPro stuff, and it has been rock solid.

In general I’m grumpy about the modular power supplies provided by networking and extender manufacturers. I suppose that the company’s purchase agent became a hero by sourcing the cheapest possible supply. I travel with a voltmeter and some replacement power supplies. An early diagnostic step is to measure the supply’s voltage. Quite often the problem is easily solvable at this point.

Sometimes I wish that there were power supply strips, similar to multi-outlet strips, that could replace a gaggle of modular supplies. This would certainly lead to neater looking installations. Yes we’d need to work out a scheme to keep track of which end unit needs which voltage, but this cannot be any worse than keeping track of which modulator supply belongs to which unit.

They do make rack mounted low voltage power supplies. If I have at least 6-8 devices, I usually install one.

I’ve installed probably 20-30 of those B-260s. I’ve had a few issues but all have been resolvable. Two of them I tried using the USB outlet on TV & wouldn’t work. Once I used the shitty supplied wall wart it fixed both. So now I always use the supplied power blocks.

Another issue we switched to Toslink on accident so wouldn’t pass hdmi.

Other than that had a couple take awhile to sync but then work just fine. Most fire up and pair just fine.
Knowing that Gold went up a few K makes me think "well now I have to do a better job on selling more equipment".
