Earlier issue - Audio Volume reduces considerably on accepting the mic permissions https://bugs.webkit.org/show_bug.cgi?id=218012 From the 15.4 beta version the earlier issue got fixed. But it reproes again if we enable / disable the mic permission and then minimizing and then again maximize the safari. Steps :- a) Start the audio rendering of webRTC stream via HTML element in safari browser b) Enable the mic capture. Disable the mic capture. Minimize the page. c) Open the page again. Low audio volume issue reproes.

Please use the below steps to to repro this issue on a standalone app Case 1 a) Open https://ashishanand26cs.github.io/lowvolume on safari b) Press "Start" button. Audio tone will play c) Press "MicAccess" button. Mic capture will start. d) Press "MicAccessStop" button. Mic capture will stop. e) Press "ResetAudio" button. Observer the audio tone volume reduces Case 2 a) Open https://ashishanand26cs.github.io/lowvolume on safari b) Press "Start" button. Audio tone will play c) Press "ResetAudio" button. Observer the audio tone volume remains same. If we enable/disable the mic access then the volume of audio track reduces considerably

The audio level in use currently change when starting to capture. When stopping to capture, we keep using the same audio level until the audio is stopped. Can you try and make sure the same audio levels are roughly the same? If that solves the issue, your request might be that you would like the page to stick with one audio level throughout the audio rendering. Is that correct?

Is this possible to keep the audio volume constant on a page?

Disable the mic capture. Minimize the page. > c) Open the page again. Low audio volume issue reproes. The issue you're encountering appears to be a regression in Safari where enabling and then disabling mic permissions followed by minimizing and restoring the page results in significantly reduced audio volume for WebRTC streams. This is similar to a previously reported bug that was fixed in Safari 15.4 beta but seems to have re-emerged under specific conditions. Steps to Reproduce: Start audio rendering of a WebRTC stream via an HTML element in Safari. Enable mic capture permissions. Disable mic capture permissions. Minimize the Safari window. Restore the Safari window. Observe that the audio volume is significantly reduced. Possible Workarounds: While waiting for a permanent fix from Apple, consider the following temporary workarounds: Programmatic Restart of Audio Stream: When the page is restored (using the visibilitychange event), programmatically stop and restart the audio stream. This can help reset the audio volume to the correct level. document.addEventListener('visibilitychange', () => { if (document.visibilityState === 'visible') { const audioElement = document.getElementById('audioElement'); audioElement.pause(); audioElement.play(); } }); User Prompt: Prompt the user to manually toggle audio playback (pause and play) after restoring the window. This isn't ideal but can be a temporary user-driven fix. Microphone Handling: Avoid disabling the microphone if not necessary. If you need to toggle mic permissions, consider handling audio stream reinitialization more gracefully. Volume Reset: Manually reset the volume of the audio element when the page visibility changes. document.addEventListener('visibilitychange', () => { if (document.visibilityState === 'visible') { const audioElement = document.getElementById('audioElement'); audioElement.volume = 0; audioElement.volume = 1; } }); (In reply to asanand from comment #0)
