[Dr_Dave_Barr]

What best describes your playback issue?

· Music doesn't start when I press "Play"

What type of Zone is affected by this problem?

· *Network Zones* are affected.

Do you have an approximate timestamp of when the issue last occurred?

· the problem files are AAC44.1,257kbps all others are fine

What are the make and model of the affected audio device(s) and the connection type?

· Once again not an issue

Describe the issue

The issue only involves files with less than 16 bit density

Describe your network setup

no problems

Does this mean that you confirmed that other AAC files work, just specific AAC files don’t work?

Or is it simply AAC generally not working? In this case, what is your Roon Server running on?

Yes that sounds plausible. Roon will also not play 18- or 20-bit files. I think it is save to assume that Roon can only play 1-bit (DSD), 16-bit, 24-bit and 32-bit integer PCM files and, to be on the save side here, that are stereo (2-channel) at least – please don’t try to play real mono files.

And there is the not so helpful (because it misses the exceptions I listed) guide from Roon Labs:

FAQ: What audio file formats does Roon support?
