Actual Behavior

After player has paused:

• mpc play -> shows the player as 'playing'. No audio output, no movement in playback position
• mpc pause then mpc play -> Same as above. Correct player status is shown, but no playback
• mpc stop then mpc play -> Plays as expected

I can't reproduce this problem, but since your log clearly shows you didn't ever try to resume playback, this bug report is bogus anyway.
