I think I read others with different Roku TV brands also noticing lower volume -- I think the Sharp brand has some kind of "TruVolume" setting that was turned off after the update, and turning it back on did the trick?
I myself had a TV speaker issue with a TCL Roku TV -- the left speaker array module had practically no tweeter output, and the overall perceived volume (especially for speech) was halved. Previous listening volume of 20-25 had to keep raising to 40. But this was a longstanding problem outside of any Roku OS update (and this particular defective set had other problems where I had to replace the mainboard and Wi-Fi module as well).
Good afternoon. Last night, I noticed low voice audio and louder background/sound effects on my new Hisense 4K 43" Model 43R7 when watching a movie through my Plex server. I don't know if that is tied into the problem being discussed here, but I thought I would put in my two cents worth.

I have just bought this TV and it updated to the latest Roku after setup so I can't compare to previous versions, but the audio volume is really low. I am using ARC over HDMI to send the audio to my receiver. If I just listen to music or use my Xbox connected to my receiver only need to volume set to -30dB (volume level 52 on Roku TV) max, to hear Netflix on Roku I need it set to -15dB (volume level ~70) or more.
It seems to be an issue with the Dolby Digital encoder. If I turn the volume up to 70 on Roku I can hear terrible noise, crackling and popping, but if I switch the ARC/SPDIF setting to PCM it goes away. This is obviously not a work around as PCM is only 2.0. It also doesn't really help with the volume as when the TV downmixes the 5.1 content to 2.0 to output it as PCM it still ends up really low volume. The crackling is also manifest when playing content from Netflix when I have the volume levels set high enough to hear it, is there no way to just pass-through the audio directly?
PS Also had volume issues with a movie from the Roku TV channel, it's not just Netflix. PPS. Also worth noting that I tried a optical audio cable and it made zero difference. Same issue.
