Hi…..Roon server on macOS Tahoe displays 24 bit 192khz audio file whilst on Arcam Radia SA45 metadata shows the file is MP3 @ 128kbps
Somewhere the audio file is downsized to an MP3……. I have the MacBook connected to my router via Ethernet as is my SA45 …..
Can anyone help?
The signal path should show what’s going on. Can you post a screenshot?
Is the SA45 actually playing music from something like Spotify’s free tier triggered by someone’s phone?
No the SA45 is playing audio from Roon server…… but not in High Res audio…..
I have tried logging out of TIDAL and resigning into TIDAL via Roon
Just tried connecting SA45 via wifi to the router and the Roon server is on the same network as the SA45 now the audio track is playing on the unit but no audio….strange?!?
Now I have tried re connecting SA45 to the router via ethernet ….Roon server is also connected to Router via ethernet. But still no audio….
Fixed no audio from SA45 did a reset of SA45…..now I just need to get the metadata showing High Res audio information…..still no joy….
Signal path looks fine. I’d suspect the SA45 is confused. Does it show the ‘wrong’ signal data for all tracks?
You might try connecting using (eg) Chromecast rather than RAAT/Roon Ready and see if you get the same result.
It might be worth checking if there is a firmware update available for trhe SA45.
Hi Andy…..Firmware was updated when originally set up by myself. The main issue is no signal of the audio file is displayed in the SA45’s screen….although track name and artist name is displayed.
When there is metadata of signal path displayed in the SA45 screen it is showing MP3 128kbps
I will try using chromecast instead of Roon Ready….. to see if that resolves the issue.
Thank You.
Now there is another issue…before I reset the SA45….chromecast via the SA45 was showing in Roon audio settings….after the reset….it has now disappeared…..Give me strength!
Reboot everything, and go and make a cup of tea…
Chromecast (when it’s working… ) isn’t really a resolution - you probably want RAAT once you are happy it’s working correctly - but it might help diagnose what’s going on.
RAAT doesn’t encapsulate mp3 even if the source is mp3 - it’s unpacked on the Roon server and sent as pcm - so I can’t see any way the SA45 could interpret a RAAT stream as mp3 unless it’s very confused. The other possibility is that what you are seeing on the SA45 isn’t telling you what you think it is, but… 
Does the same file streamed using Tidal Connect display correctly?
No using the SA45 via TIDAL Connect everything is as it should be…..signal metadata of audio files are displayed on SA45’s screen……it is just on ROON the audio metadata isn’t. And if it is at all…it shows MP3 128-320kbps Have emailed Arcam support …..Lets see what they have to say…..
Even though the max bits per sample and max sample rate aren’t being displayed on the SA45 whilst using Roon I can hear the difference between a 16 bit 44.1khz audio file and a 24 bit 192khz audio file. It would just be handy to see the actual bit rate and sample rate on screen.
You might post in the @support category too - not sure if this tag will be seen.
Support requests must be posted through the form now, has been the case for quite a while. This is to ensure they get a ticket number and are properly tracked
Aye - but I didn’t realise the tag no-longer worked… 
Indeed, this was another change that the mods told me at the time. I think it was done to enforce the “must have a ticket number” rule
