I am posting this again because I am totally stumped as to why I cannot seek within a track when playing off the SD card. The files I am playing are not yet commercial releases, they are exported directly from my DAW. (I'm a mastering engineer) Each song is its own wave at 9632. No matter if I use Bubble, Glider or MConnect if I try to seek by sliding the cursor L/R, or holding down the rewind/fast-forward, the song either returns to the beginning or skips to the next song.
This seems to be isolated to playback on the Poly only. When I "play to" or "Render To" Googlecast I can skip around within the song on the SD with no problem.
As an audio engineer I want to drop my work on to the SD card then proof it while away from my studio. If I hear a click or something I have to start the song over instead of rewinding a few seconds. This seems like such a basic function.
@Matt Bartlett Why is Poly behaving this way? Is there a particular way I need to prepare the wave files?
