Confirmed, it did. the steam cache seem will seek to the track just
before the target track and pre-read some bytes in the privous track,
that cause the seek fails since we set it in command line to only play
track 2, so seek to any part of track 1 will fail.

I will futher check why the steam_cache read ahead of target address.
