Crackling and static audio Roku Ultra
It is on 2 different Samsung Tvs connected to Roku devices. One device is a brand new Roku Ultra (bought partially to fix this issue, did nothing for it), the other is another Roku Ultra from about ...

You didnt mention the Ultra's model # (there are many, with differences) or RokuOS version/build (there are many, with differences).
You also didnt mention your Samsung TV models or any AVR/SBs brand/model, or how you have them connected (to TV or AVR/SB, etc)
However, if your Ultras are 48xx models (Settings/System/About), make sure of the following:
1) Configure passthrough: Settings/Audio/Digital output format = Passthrough
2) Disable sound modes: During playback press Options (*)/Sound Settings/Customize Sound Mode/Volume Leveling and/or Dialog Enhancement = Off
These settings are known to cause crackling/static/noise and volume issues in some/all setups.
Otherwise some older AVRs/SBs/TVs (~12-15 years old) have a buggy DD+ (decoder) version known to cause such behavior, so its best connect around (or update/replace) them.
My TV is about 8 years old, so not the issue you mentioned, my Roku is connected directly to the TV thru an HDMI cable. I just bought a new Roku Ultra, because I had an issue with the last one buffering and then jumping to the next show before it was done, so I purchased a new Roku because mine was about 8 years old. The new Roku is a 4802R, so I did change the settings as you directed, so I will see if that helps. thanks!
