The issue in general is hardware related but on Windows it is lower, barely noticeable. Here is a description of other users: https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/T440s-speaker-no... The second issue is that when you activate audio suspend a loud cracking noise is emitted. This also doesn't happen on Windows where the audio device is muted automatically if not used without any clicking. It is only noticeable because the low background noise disappears. -- You are receiving this mail because: You are on the CC list for the bug.
