Regression: Audio corruption in HLS playback on Chrome 138 after #EXT-X-DISCONTINUITY tag

[Hiroharu Tanaka]

Hello,

I'm trying to report an important bug but I am consistently blocked from creating an issue on issues.chromium.org.

I have already tried all standard troubleshooting steps (clearing cache/cookies, using a different browser, different network, and even a different Google account) without success.

I would like to report a bug, but I am unable to create an issue on the Chromium issue tracker due to a persistent "Failed to create issue: Error: sf " error. I am posting the details here instead.

Subject: Regression: Audio corruption in HLS playback on Chrome 138 after #EXT-X-DISCONTINUITY tag

Description: An audio playback issue has been identified on Chrome version 138 when using a browser-based video player built with Hls.js.

Conditions: The issue is confirmed to occur exclusively during playback following a video segment transition marked by the #EXT-X-DISCONTINUITY tag.

Additional Information: A recent update seems to have introduced this issue, as audio playback functioned correctly in previous versions of the browser.

Note: This issue appears to be related to an existing bug report:

I appreciate your support.

I have just attempted to submit it again, but unfortunately, I encountered the same error.

I will try again after some time has passed.

Thanks,
