ST30 not playing M4A files

Hi community

I have several albums (originally in FLAC) that I wanted to be able to listen in both home and car environments, so I converted them to M4A using Media Human Audio Converter with following parameters: Output - AAC(M4A), stereo, 44100Hz, 320 kbps. Files are placed on NAS for DLNA distribution and on USB flash for car headunit and they play nicely in my car Kenwood head unit.

When I open files from NAS with ST app, I get error 1604 saying OOPS We can't play tracks with that audio file format. Try something else. I converted them to MP3 - everything is fine, ST is playing them nicely. I also tried to play some albums bought from iTunes - and I get the same error!

I cannot reconvert all albums to MP3 as FLACs have been long deleted, and converting albums from M4A will lead to loss of quality, furthermore, my car headunit sounds better with M4A than with MP3.

Is there any solution to this? Latest firmware and ST app versions have been applied already.

These are details for M4A file generated with Media Human Audio Converter:

Re: ST30 not playing M4A files

Seems that problem was related to DLNA server (UPnP Media Server or UPnP Media Server V2) on my ASUSTOR NAS. Installed Twonky, and everything is fine
