Roku Ultra 4802X Software 11.5.0 build 4312-C2. On 5GHz WiFi band. Vizio Soundbar 2.0 connected to TV with Optical cable. Digital Output format set to Passthrough.
Audio drops out for several seconds almost every minute or two on YouTube Channel (both live and old). I notice many have posted this issue. I had the same problem with my older streaming stick so upgraded Internet speed, bought Gigabit Dual band Wi-Fi 6 Router and new Roku Ultra (I know Ultra not WiFi 6 caapable). Upgrades did not solve it. I have great WiFi signal and minimal interference on 5GHz WiFi.
Roku Ultra does NOT drop on AMAZON PRIME or ROKU. I do not have any subscription channels like Netflix so do not know if those affected.
Is there something different about YouTube for all Roku devices to have this problem? I cannot find solution. Seems to be only on YouTube.
