Data Disc Playback Issue On PST

When playing an audio data disc (DVD-R) on the PST, the machine does not play the track selected.
For example, If track # 1 is selected, another track, let’s say track #7 plays even though the display shows #1 being played. I cannot select any particular track or album on the disc by selecting the correct track number. Also, tracks are not played in the proper numerical sequence.

This is a real problem if there are 36 or more tracks on the disc.
As such these discs are rendered practically useless especially when playing classical music.
Unfortunately I have 500+ audio data discs (about 1800 LPs) which are affected by this problem.

I have been making these data discs for 8 years and there was never an issue playing them back on either the PWT or the DMP.

All files are in the root folder, not a sub folder of each disc.
The audio data discs are made using Nero software.
All files are named in this fashion: track #-Track Title.wav

Has anyone in this community experienced anything like this?
I have contacted PS Audio regarding this and their engineering team is looking for a solution.
I would hate to have to return the PST as the SQ on this thing is fabulous in my opinion and SACDS and CDs play without any problems.

It happens also when you play from a jump drive via the front panel USB port. It plays what it wants to, when it wants to.

I played a data disk for the first time last night and it didn’t play the track number I thought I had selected.
Maybe I had done something wrong but now that you mention it, I doubt if it was my mistake.

This is what I found out during early day of beta testing last year.

  1. usb/ data disk play back follows the file created time not the filename order. Basically, FIFO. - first copy in, will be first playback.

  2. also did a non scientific “response time” counting from disk start to spin to the display show track

  • Music CD. 13 tracks. 7 seconds
  • Music SACD 12 tracks 7 seconds
  • DVD+RW. 4 tracks 22 seconds
  • DVD-R. 18 tracks. 17 seconds
  • DVD+R. 32 tracks 57 seconds.

In my opinion, PST is primary designed as SACD/CD transport for DSDAC. And with Octave Music Player | PS Audio in the pipeline, supporting the music data file playback in PST is secondary.


Good info…thanks for sharing.
