A different take on this...
ogg123 prints it's progress. You could start a frequent sync in the
background (if the default system sync isn't frequent enough). Then
redirect stderr of ogg123 to a file. Later you can examine the last
timestamp in that file to see how far you got. Looking back farther
in the file you can also find which file was being played.
$ ogg123 TheBrightestStar.ogg 2>oggtime
$ tr '\015' '\012' <oggtime
Audio Device: PulseAudio Output
Playing: TheBrightestStar.ogg
