We need more information for us to assist you further. Can you please specify the issue you are experiencing? Does the issue only occur when streaming on a specific channel or all channels on your Roku device? What troubleshooting steps have you already taken to try to resolve the issue?
Volume spikes and reductions occur on most channels but mainly on Fox, CNBC and local Philadelphia stations. A return to normal is obtained if I advance a channel and then return to the channel having difficulty.
We have had this problem of very loud bursts of sound for some time on two different units. All channels, random times, turning off and restarting the Roku unit is the only solution. It would seem that there has been enough info posted to give Roku a picture of the problem. It would be interesting to hear a technical explanation of just what is going on. And, of course, a solution!!
