2 problems with FLAC download and playback

[JeffBDVS]

Hi All,

I have 24/96 and 16/44.1 FLAC files (with embedded album art and metadata) stored on my desktop Windows 10 PC. I'm interested in playing back hi-res audio files from my iPhone (using an external DAC and amp connected to the phone). I have a couple of problems getting those files into VLC for iOS.

1. When I use Sharing via WiFi, the uploaded tracks from the PC appear in the VLC Media Library, but without the album artwork. The metadata seems to import because the song title, album title and duration are correct. When I import the same tracks into VLC via iTunes, the artwork and metadata both come along for the ride. If I upload the same files to Google Drive and then download them to VLC for iOS, the artwork and metadata also appear as expected in VLC. It's only the Sharing via WiFi that doesn't include the artwork.

2. I use Asset UPnP (from the folks who make dBPoweramp) as a DLNA media server to my A/V Receiver. It is also available on my iPhone through my receiver's iOS controller app. The thing works great as a software DLNA server. Asset UPnP shows up in VLC for iOS under the Local Network tab. When I try to stream or download a track from Asset UPnP in VLC, I get gibberish in the track progress bar during streaming, and an invalid format error message when downloading. Note that the files I'm trying to stream and download are the same files that import successfully using the methods described in #1. The end result is that I can't use Asset UPnP to serve up my music in VLC.

Please help me resolve these two issues. Thanks in advance.

EDIT: Sorry -- I didn't include my device info: iPhone 6S 128 GB running iOS 9.1.

Cheers,
Jeff
