Hi Sam,
This post is a long time in coming, but you know… life. I received my Vero 4K many months ago but only got around to setting it fully up a month ago. At a high level, its a great device, however, there’s been a couple issues I’ve been struggling with and have only recently had the time to dig deep into them.
First my environment:
3.1 dual sub Polk Audip speaker system
Onkyo receiver set for direct (no DSP processing)
Vizio low end 60" LCD monitor
Before the Vero 4K I had been using an old Intel NUC running Kodibuntu. For comparison, I flashed it today with LibreElec today so both the Vero and NUC are running Kodi 17.4.
Now the issues.
First, there seems to be a serious problem with the Vero 4K audio mixer. Both V4K and NUC are configured for 3.1 channels with stereo upmix and passthrough enabled. With the same 2-channel source, the NUC correctly up-mixes to 3.1 channels with actual content being provided on both center and sub outputs. With the same source, the V4K is sending a 7.1 PCM signal with no output at all on either center or sub channels. It seems stereo upmix is enabling all possible channels while not doing any actual remixing at all.
The second problem is with the amcodec video hardware decoding. It seems about 1 in 5 h264 video sources drop 99% of the frames. ie. I get solid audio playback, but video only provides the occasional still image update. These same sources play flawlessly when amcoded accelleration is disabled. These sources also play flawlessly on the NUC with VAAPI acceleration, as well as my linux laptop. I’ve read through some other the threads regarding this with John Oliver seemingly being problematic. I’d extend that to almost anything from HBO, but the fact is its only the amcodec that seems to have a problem with these sources, so I’m reluctant to agree that its a problem with the original transcoded video, and I’ve yet to see a PROPER posted for any of the episodes I’ve had problems with in the last month.
I can live with amcodec being disabled, as software decoding still manages my highest quality movies. As long as running the CPUs at 95% isn’t going to cause thermal issues down the line. Unfortunately, the audio mixer is a deal breaker if it can’t be resolved. As is, the V4K audio sounds thin and lifeless compared to the NUC. The reason I use Kodi to upmix is so I don’t have to keep switching the receiver’s DSP modes.
My free time for projects is limited, but I’ll do what I can to help resolve these issues.
ps. before I forget, how can I turn off a lirc remote config? I was playing around with the remote setups when I first got the V4K, and now my NUC remote is controlling both lol
