Certain videos that previously played normally have developed sudden audio issues in Telegram for iOS. The issue affects videos processed using different methods, with varying types and severity of audio defects.
Two types of issues have been observed:
Severe crackling: Videos processed using one particular method produce very loud, persistent crackling throughout playback in Telegram's built-in iOS video player. This crackling is not present when the affected videos are downloaded and played outside Telegram.
Subtle audio distortion: Videos processed using a different method exhibit degraded audio quality, faint crackling, or background noise. These defects are also present in the downloaded video files.
Before October 9, 2026, all these videos played without noticeable audio defects.
The issue appeared suddenly, suggesting a possible connection with a recent change in Telegram for iOS, although the exact cause is unknown.
The affected video files cannot demonstrate the severe crackling when submitted through the support website because the crackling occurs specifically in Telegram's built-in player and is absent from the downloaded files. An alternative method for reporting or demonstrating this issue may be needed.
Steps to reproduce
Open Telegram on an iPhone running iOS.
Open a chat or channel containing one of the affected videos.
Tap a video to play it using Telegram's built-in video player.
Listen to the audio and observe the audio quality.
Repeat the same steps with other affected videos processed using different methods.
Download a video affected by severe crackling and play it outside Telegram.
Compare the audio playback in Telegram with the downloaded file.
Current result
Since October 9, 2026, some videos produce loud, persistent crackling throughout playback in Telegram's built-in iOS player, even though the downloaded files do not contain this crackling. Other videos exhibit degraded audio quality, faint crackling, or background noise, and these defects remain present in the downloaded files.
Expected result
Videos should play with normal audio quality in Telegram for iOS, without crackling, distortion, or background noise, as they did before October 9, 2026.

Yes, I sent them videos with the glitches, and they said they would investigate the issue. But honestly, I feel like they have no intention of fixing it😢
