Poweramp 2.0.9 build 548 full Gbox Midnight MX2 Android 4.2.2 I run flac files ranging from 44kHz to 192kHz off an external hard drive via USB. I disconnected/reconnected the drive for the purpose of adding about a dozen files. Prior to this, everything was working perfectly for the 2 days after i installed the new build. After reconnecting and running a manual quick scan, playback became incredibly choppy (often pausing every few seconds) on almost all songs no matter the sampling rate. Also, i started getting a "Failed to play file..." message on several of the songs with an 88khz and above sampling rate. I rebooted the GBox and also did another quick scan and that accomplished nothing. I then ran a full scan, and this seemed to fix the choppy audio problem i was having. However, i'm still getting the "Failed to play file" message on about half my higher sampling rate files. To which i noticed that on the files that won't play, (about 150 of my 300 or so 88khz and up songs) all tag encoding has been erased. I can't say if this occurred before or after the full scan, but i can say with 100% certainty that it happened sometime after my plugging the hard-drive back into the GBox. As a sidenote, it would appear that with a few exceptions the tagging was erased as much on a "by album" basis as opposed to a "by song" basis. In other words, if one song on an album had it's coding removed, all songs on that album did also. At least for the most part. Thanks.
