Unable to stream 192kHz on DSM 5

This suggests that the NAS is consuming 100% CPU when transcoding 24/192 files. Another possibility is that the NAS is running out of RAM. What is the exact model of NAS? How did you check the CPU consumption?

Another thought: the FLAC compression level can affect CPU consumption when transcoding. Did you rip the 24/192 file yourself? If so, what level of FLAC compression did you use?

This is a bit embarrassing but I've just realised that my previous quick check of CPU usage looked at my Duo, not the NV+. I don't have a monitor app for the NV+ so can't see what the CPU and memory are doing. Do you know of a suitable add-on for the ARM processor model (NV+ v2)? Alternatively is there anything in the logs that will give a clue on CPU and memory?

Regarding the box, it is a ReadyNAS NV+ v2. It has 256Mb of RAM.

I had a look at the logs (happy to send them to you, if helpful) and it does show that there isn't a lot of memory free - about 20Mb by the looks of things.

The files I'm testing with are a sample Studio Master file from Linn (actually a 24/88 file) so received already packed. It is 42% compressed.

The other is a file I ripped myself with dBpoweramp. The compression is set to Level 5 (their standard) and the files show as 30% compressed.
