Volume on MacOS (14.5 Sonoma) very low

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

Microphone line level on MacOS is too low, causing low volume. This is effectively identical to #4968, which had no activity on it.

Steps to reproduce

1. Make a video call from MacOS.
2. The volume will be extremely low to the person you're talking to.

My husband and I just had a Signal video call. Originally it was my iPhone and his computer. On my iPhone his audio was quite faint. On his Mac, my audio was fine.

My iPhone ran out of battery, and I called back from my Mac. Once I called him back, my audio was quite low for him.

Microphone input level to max in sound settings; output volume set to max—on both ends. Nevertheless annoyingly and occasionally incomprehensibly faint sound.

Expected result

Normal volume for audio call: same as FaceTime, Zoom, etc.

Actual result

Extremely low microphone levels.

@kredati Hey there - I'm sorry you're running into volume issues. We'd still like to see a debug log to better diagnose what's happening. Can you provide that?

I have the same issue, also on MacOS 14.5 Sonoma.
Appears both with audio/video calls, and when recording a voice message. With telephones, the audio input level is okay, but not with desktop.

I'll be happy to provide a debug log if you advice how to provide that.

You can provide your debug log at View -> Debug Log, then upload it and provide that URL here. Thanks!

You guess what :)
Last night, the MacOS updated to version 14.6.1 (23G93).

...and now, as I was gathering data for the debug log, the audio issue is gone!
Perhaps this was all related just to MacOS 14.5?

I am still having this issue on Macos Sequoia 15.0.1. I have attached the debug log.
