Apple TV Rocks

Got myself an Apple TV 4 last Monday... Very happy with it. It is definitely a step up from the streamers I have been using thus far... PS4, Sony BDP-6700, and Chromecast. It is very responsive and streams at full speed within a couple of seconds. Also no bugs with multi-channel audio like the one I have been experiencing with Chromecast recently.

Fox Sports just released their Apple TV app Friday. The stream quality and the 4 pip streams is awesome for sports. Look forward to using this for the upcoming fall games. ESPN needs to implement this 4pip asap with all their espn3 sub content. Great feature for all the games on Saturday and Sunday!

Have experienced some playback issues with Plex and AppleTV4. Attributable to network throughput origins. ALL my other media playback devices that can do Plex work fine, a ROKU 4 I'm playing with, even Sony bluray player and using Plex as a DLNA server. Laptops, etc., all fine.

Read to try and connect via wireless. I was wired.

Changed it now to my 5G AC channel and so far no issues. Still need to play movie a little longer but its not stopping nor buffering.

I also experience playback issues with Plex as well. One issue is that I have to turn off Allow Direct Streaming if I want the playback quality set to 20 Mbps or higher or else Plex on my Apple TV 4 will display instances of stuttering and artifacts on some titles and I noticed that Window Resource Monitor shows Network usage hitting 100 Mbps during those stutters and artifacting. 100 Mbps is the limit of the Apple TV 4's ethernet port and it seems to be getting saturated during those instances. Disabling Allow Direct Streaming lowers the network bandwidth usage to around 70-80 Mbps in those same instances. Maybe this is the issue you are talking about since you mentioned network throughput. I'm using an ethernet connection to my Apple TV. Wireless is not an option for me since my Apple TV is too far from the router to get a good signal.

Seems like the wired ethernet port, or how its managed, is the problem on the AppleTV 4. Came across several threads about it and the Roku4 too. People getting way better performance by switching to wireless.

It is in fact better. Watched several movies and no issues at all.

Was ready to cave on Plex until trying the wireless connection.

Anyone connecting remotely, all two of the folks who tested it, had no issues remotely. Its just been within my LAN. IMHO that should not be. But it is what it is. Glad to see it working without buffering, etc.

It is just the AppleTV on my LAN that has the issue. Would think it could be my network some how IF the other devices having issues.

Interestingly the VLC App for the AppleTV 4 plays video back as well. But it doesn't do multichannel audio.

So its something between the Plex App and the AppleTV 4.

Also I'm using an i3 for the Plex server.

VLC on my Apple TV 4th generation will do multi channel audio. I can get it to bitstream AC-3 to my AV receiver. But there is a small audio glitch/spike when the file starts to play. After that though, it's OK.

Having used my ATV4 for a more than a week now I do notice that I have to turn up the volume by about 8 to 10 DB compared to when watching Blu-ray discs and also streaming from other devices to get the same level of sound. I also seem to notice that the dynamic range appear to be more limited on the ATV4 (again compared to the other input sources) even though I have this setting turned not to limit dynamic range.

I am hoping the next update will incorporate fixes to these issues.

I have my Plex set to boost the multi-channel signals. Otherwise my AppleTV 4 Plex audio is lower than Plex through my bluray player.

New TVOS today. Can any latest gen owners confirm if the audio issues have been fixed/improved?

The ones documented during the past 8+ months in this thread and on Apple's user forums. Here is a small random set of quotes, but if you are really interested, read the last dozen pages of this thread.

Firstly, as also mentioned in other posts, test with SPL meter for peaks and FFT peak charts (attached) showed, that output after multichannel decoder is about 8dB lower than on ATV3 or on the same ATV4 running in Stereo mode. But also I noticed, that on ATV4 (Best Surround or Dolby Digital mode), after multichannel decoder, output seems to lack frequencies above 14..15kHz. Not sure if it's filtered completely or just runs at much lower level. Didn't have time to test more. Probably that is what makes multichannel sound out of ATV4 not only weaker by 8dB (which by itself is hardly acceptable for normal use), but also (subjectively) limited in quality. In Stereo mode set on ATV4, frequencies above 14kHz seem to be similar to ATV3. In Dolby Digital output mode, as expected, practically no difference from "Best surround" mode. Anybody else have noticed it?

P.S. Attached charts are FFT peaks on AudioTools with default settings, using internal mic on iPad. Signal input gain levels on receiver are written in file names (Plain ATV4 charts are +8dB, ATV4 Stereo - no additional gain, ATV3 - no additional gain). Have case open with Apple to check, if there is any fix possible and in sight.

EDIT: FFT charts are created by "listening" to the same 1min of Red2 movie (HD) streamed from iTunes store.

These files are intended to help adjust the individual speakers in a surround system to reference level, and there's one file for each speaker. The program eac3to does not report anything for dialnorm for these files, so I guess it's 31, i.e., no attenuation. Even so, I find the ATV 4 plays the .mp4 files about 4 dB lower than Kodi plays them as measured by my Radio Shack SPL meter, with the ATV outputting PCM and Kodi configured for WASAPI passthrough. No idea yet about the dynamic range.
