On macOS, you always get your own 'timeline' for the AudioUnit session, so timestamps start from 0. On iOS however, AudioUnit seems to give you a 'shared' timeline so timestamps start at a later, non-0 point in time. Simply offsetting seems to do the trick. This was causing osxaudiosrc to not output any sound on iOS. Regressed in 2df9283d3f2ea06af5ebd6db03a6d545cac52f19 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/7856>
