I have a Hisense 48h4c Roku TV.
Software Version: 7.6.0
* The interface is, in general, much slower/laggier. Sometimes. Let me explain:
* Sometimes (usually the first time opening the app/channel) pressing volume up/down on the remote, and it takes ~2-3 seconds for the volume indicator to show up on the TV
* Most times when going from a channel with "lag", to another channel, then back to the original channel, the "lag" vanishes, and everything is responsive again.
* However, over time without any input from the remote, the "lag" returns, and when I press volume up/down/etc, it can take ~2-3 seconds for the volume indicator to show up on the TV again
* The main difference is that it's just now lagging for that first action. For instance, if I press volume up after a length of time with no remote input, it lags. But, pressing volume up/down again within a few seconds, and there's no lag.
* Pressing the "Home" button on the remote when in some channels/apps, it takes 5-6 seconds to go back to the Home screen. Not all apps/channels. For instance, it takes 5-6 seconds to go "Home" from within Netflix, but there's no discernable lag when pressing "Home" while in the Plex app.
* Netflix defaults to 5.1 audio, even though my Roku TV audio settings are set to Stereo. Audio defaulting to 5.1 seems to be the case for most (all?) apps/channels, actually. In the case of Netflix, it doesn't seem to matter, as I hear zero difference between choosing the 5.1 audio stream or the stereo audio stream (though it's interesting to note the bandwidth used is very different; ~2 Mbps when using stereo audio, and ~6 Mbps when using 5.1, so the bandwidth differences would probably make being able to have Netflix/channels actually recognize my stereo output and select stereo as the default audio...useful).
* However, 5.1 and stereo audio sounding the same on my Roku TV's stereo output isn't the case for some other apps/channels, such as Plex. I have video files with 5.1 audio on my Plex server, and their volume is quite low via the Plex app on the Roku TV. However, if I manually transcode a file to stereo audio, the volume is much louder on my Roku TV. It was my understanding that the Plex app is supposed to automatically transcode audio/video based on the player capabilities (ie: Roku TV in this case). It's not decoding 5.1 audio to stereo, it seems. Is this because apps/channels have no way of discerning what the Roku TV's audio output is and just assume it's 5.1?
I'm not sure how many of these issues are specific to 7.6.0, Build 4117, though I'm pretty sure the remote input lag is new to the update.
Just thought I'd share.
