Issue playing video with FLAC audio on Roku App 4.1.15

I am having issues playing several videos which contain only a single audio channel which is FLAC. Sometimes the audio won't play at all. Other times it will start to play but then the video will run like it is fast forwarding (sync issues). Skipping around in the file usually results in no audio. All of these functions work as expected on my other playback devices. I've played some FLAC CD rips and they seem to play fine on the Roku. My server is Version 4.8.1.0 on Linux.

Hi guys. My problem is similiar to yours except that I am playing a FLAC audio (only) file. It is on a Roku TV and the app is the latest version. At any rate, the audio is like REEEAAAALLLY slow. Worse than playing a 45rpm record at 33rpm. Weird. As far as I can tell, this is the only file that is doing this. I think other FLAC files are fine....anyhow, just thought I'd throw this out there. This screen shot probably doesn't help, but this is from the server....there is no "error". The file play
