I posted this over at RME but i think due to the uniqueness of my problem, i am going to need more eyes so i thought i should post here too.
I am a new owner so appreciate your patience. Have gone through the 100+ page manual a dozen times but its clear, experience will add dramatically to my knowledge of how to use and appreciate all its flexibility, of which i have none.
My setup
A raspberry pi, usb output to the ADI2pro/fs/be. I use jriver as my player. Within jriver i am running the parametric equalizer to smooth out room modes (measured with umik & REW). I run the analogoutput from the ADI2 to feed my desktop active/sub speakers (neumann). Additionally, at times, i will also the aes output found on the breakout cable to feed my family room active/subs (dutch8cs). My source is a large local file library using jriver which also allows me to stream amazon music.
Performance is supurb and works flawlessly playing, flac, hires , dsf, mp3 and wav music files. Never had an issue with any format or sample rate. Whatever i throw at it, works.
I purchased a matrix element s (streamer with digi output). Inserting the matrix for the raspberry pi and keeping everything else the same I am having problems playing any file that has a sr above 48k.
Here is what is strange
- at times the matrix/rme duo barf at a hi res song yet other times it plays that same song without issue. The inconsistency is amazing
- it typically only barfs (stutters, drops out, stops etc) at 192k but once it barfs and until i reboot the rme, all other lower res songs that have played fine, now get the same barfing action.
- I tried using the optical output from the matrix (instead of usb) but there was no change in not being able to play hi res files.
- Clearly its a defective matrix, right? no, not really becauase if i insert the matrix in another setup (matrix usb output to emotiva pre/pro) i have in a different room, all songs play flawlessly without problem ... even those that would not play with the matrix rme combo.
I have a file of 20secs of a 24/192k lou reed song i played on the rme/maxtrix combo and recorded on my phone. If i can attach it to my post i will so it will be clear what is happening.
I initially thought it was the matrix but it playing everything flawlessly in my other system says the matrix is likely not the problem. Then, I thought it was my setup of the rme that was at fault but if the rme pi combo plays perfectly then that is likely not the problem. Next, I looked at jriver being the problem, So, I played around with the settings and found some definitions of my dlna servers that were definitely capable of causing problems so i fixed them. Once i fixed all those potential issues, i still have a matrix rme problem as it did nothing to resolve the problem.
The manual speaks of never enough dsp power which, at hires sample rates could be the cause is the only other thing i could think may be the cause. is this a real possibilty for me? If so, why does it work with the pi?
Other than that, i am out of ideas and have nothing to try.
You may be wondering why not just keep the pi and ditch the matrix. The only reason for the matrix is i like its ability to show album art (my pi wont with jriver). While that is my preference (especially when the alternative is not being able to stream amazon and play an extensive collection of hires music), its not critical so i am ready to send the matrix back and just use the pi. But hoping someone who is much smarter and knowledgeable of the rme might have some ideas on what i might be experiencing and some suggestions on what to try next.
Thanks, in advance
