Audio Intermittency and Loss on Google Chrome 149
Dear Partners and Clients,
We would like to inform you about a technical issue reported by several clients in uContact, related to the recent update of Google Chrome to version 149, released on June 2, 2026.
The reports consistently indicate that, when using this browser version, some calls experience audio intermittency, while in others the audio from either the client or the agent is lost entirely.
So far, we have not been able to reproduce the issue in our environments, but our team is actively investigating to identify the root cause.
In the meantime, we recommend using the Microsoft Edge browser, where tests carried out with other clients have shown that this issue does not occur.
We appreciate your understanding and patience. We will keep you informed of any significant updates.
Sincerely,
The uContact Team
Update — Friday, June 5, 2026
We have detected that the issue has also started occurring in Microsoft Edge, since the change causing the problem was introduced at the Chromium level, the engine used by both browsers. For this reason, our previous recommendation to use Edge as an alternative is no longer applicable.
Our investigation determined that the browser stops the tab's audio when it remains in the background. While we work on a definitive solution, we recommend:
Avoid keeping the uContact tab in the background for extended periods.
If audio is lost, log in again to restore it.
We are continuing to actively investigate in order to reach a final solution, and we will keep you informed through this channel.
We appreciate your understanding and patience.
Update — Friday, June 5, 2026, 4:00 PM (GMT-3)
The issue has been identified and resolved.
The root cause was a change introduced in the latest versions of Chromium (the engine used by both Chrome and Edge), which suspends a tab's audio when it remains in the background. This caused call audio to become intermittent or be lost whenever the uContact tab was not active. Our team developed a fix that keeps call audio active at all times, regardless of the tab's state.
The fix will be available in uContact version 6.568. This version is not yet marked as stable: our team is performing the final validations to confirm it. We will notify you through this channel as soon as it is ready to be deployed.
In the meantime, the recommendations from the previous update remain in effect.
Update — Monday, June 8, 2026
Verson 6.568 is ready for update.
