I’ve done a dozen HDMI refreshes, bought brand new high bandwidth cables, etc, but it is just way too flaky. When I can get it working it will stop working the next time I turn it on. This is to a Sony X900F TV btw, which has only one extra high bandwidth HDMI port so I rely on the sound bar doing the HDMI switching. I have my Nvidia Shield plugged into the TV port and it works flawlessly.
There seems to be something poorly engineered around their HDMI handshaking. Just look at how extensive the FAQ on HDMI issues is on the Nakamichi website. I have a Denon receiver that I’ve never had any issues at all with many of the same types of devices, all of them 4K 60Hz capable.
I guess there is a chance I’ve got a defective sound bar, but the extensive Nakamichi HDMI FAQ suggests otherwise.
Can anybody recommend another sound bar that is HDMI 4K stable, has at least one wireless sub, and wireless rear speakers? I love the sound of the Nakamichi but my wife is getting pissed off that I spend more time trying to get the sound bar to work than listening to it.
I finally set up my bar last night (Ultra 9.2.) have not done any FW updates yet (don’t have a USB stick that is small enough
). No fancy cables, mostly what came with the source units and some certified for bar to TV and BR player and Apple TV.
I have a Sony Z9D running latest FW.
I’ve had issues in the past with various AVRs connected to it (Apple TV stops working, HDMI port 2 stops all together, etc) that were solved by a soft reset (holding down the power button on the remote for about ten seconds) which solves the issue every time.
Direct TV box running to TV HDMI 1, Apple TV running to HDMI 2 and Nak on HDMI 3
Xbox One X, PS 4 Pro and Sony X700 UHD player all to Nak HDMI inputs.
The Nak is a little slow to switch... but all sources report as expected (all 4k formats supported except Dolby Vision.).
ARC switching on bar works really really well.
I recently had a Samsung K950 sound bar and it was fairly flaky switching sources.
My point is that our sets are very similar.... and the Nak seems to work well for me so I don’t think it’s endemic to the bars design or implementation.
Maybe you have a bad bar with a defective board.
And I’d strongly suggest the tv reset. It might be that.
More than other manufacturers Nak seems to want to help their customers set up their source devices properly. And as I said my experience with Samsung was less than ideal.
