Hi @Vladislav_Shkarovski,

Thank you for the additional report, I have spit your post into it’s own thread.

We are aware of a few similar reports, this is due to the ffmpeg version and how the radio station’s stream is being sent:

Internet Radio - Some stations play only out of one channel on ROCK/Nucleus [Ticket In]

Core Machine (Operating system/System info/Roon build number) Latest ROCK on NUC installed a few days ago. Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet) Fios --> router --> NUC --> USB --> DAC Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.) TEXT GOES HERE One channel of internet radio is out (right) on many but not all stations. It mostly is contained to various streams of New York Public Radio (WNYC, WQXR, …

The dev team is aware of this behavior and we are investigating what can be done.

Hi @Vladislav_Shkarovski,

As I mentioned in my last comment, we are aware of there being an issue with ffmpeg on certain types of AAC radio stations, stations that are formatted as “SBR+PS”.

These types of stations send a special type of audio stream that is called parametric stereo and ffmpeg handles the conversion from one channel to stereo.

We have found that newer versions of ffmpeg are not converting this properly and the dev team is investigating what can be done for these types of streams.

We believe we have a good idea what is causing this issue and we hope to address this behavior in our next Roon release.

Hi @Vladislav_Shkarovski,

We’ve just released Roon 1.7 (Build 500) which includes changes that should improve this behavior. Please give it this a try and let us know how it goes!

Hi, noris! In New release I cant find my stations I created Before. Now new interface for radio

[Geoff_Coupe]

Are they not preserved in the “My Live Radio” section of your Library? The main Navigation menu in Roon now has two entries for Live Radio - the Live Radio entry, which is the browser for Roon’s Internet Radio directory, and the My Live Radio entry, which should hold the stations that you have added to your library.
