Fix playback start with sync_ptr mode

Browse source 
Fix by Istvan Varadi <ivaradi@gmail.com>

- start the playback with snd_pcm_hw_start failed with -EPIPE, because
 some pointers were not updated. I attached a patch for alsa-lib 1.0.8,
 in which sync_ptr is called before SNDRV_PCM_IOCTL_START. It seems to
 solve the problem, though I don't know alsa-lib enough to be sure that
 this is the right solution...
