5+ years later I can experience similar problems with AAC content:
According to Roon that’s TIDAL AAC 22.05kHz 24bit 2ch. Roon is unable to play them via Airplay and Squezebox bridge. Such tracks are being stopped or playback stops at 0:00.
Is there any way to make Roon properly treating such content?
Roon 1.8 build 806 on QNAP.
