Roku Streambar audio volume fluctuations—Crackle Sound on Xfinity Stream App

Newbie to Roku Community.

Roku Soundbar, Model: 9102R

I have the same issue: heavy static and loud crackling - generally during loud and/or low rumble bass sounds, and lower volume overall (especially when the static starts). 

Troubleshooting: I have power-cycled the soundbar, unplugged the HDMI & power cables for 30 seconds, replaced the high speed HDMI cable twice, cycled through all available audio setting options in my tv, and moved roku to another tv to verify if the sound issues follow.  My final step was to remove the roku soundbar and replace it with my spare roku express and a separate soundbar (JBL Multibeam).  Connected them to the same HDMI port on the same tv, using the same HDMI cable as in original set up and now have no issues.  The static and crackling is definately within the roku soundbar and there are no problems with my tv or its audio settings.

ROKU SUPPORT TEAM, please help to resolve this problem with your device.
