Qobuz comes into the house through a modem to a switch and connects to the Kala k50 via ethernet cable. From the k50 a usb output is used to input to the playback designs mpd 8 dac.
My question is why is there no cpu usage on the roon player. It shows 0 in the roon setup.
This is the case with local files as well. Perhaps using usb out bypasses the player?
Hi there, the only signal that by-passes the Player is Direct Ethernet Out.
The reason for having the Server in front is that does all the heavy lifting prior to sending to the Player.
Generally the only time the Player uses CPU resources is when it needs to transcode something that has a DAC mis-match, like trying to send DSD to a non-compatible DSD DAC and it transcodes to PCM, which is why thats a bad idea.
For example on the OLADRA on my desk, playing Qobuz via Squeeze there is a mini burst of CPU on loading the playlist, but its like a milli-second and minimal usage then nothing, for DSD 256 there isnt any usage.
And thats exactly what you want, you dont want noise close to the DAC, by design.
We will be re-designing this in future software.
I’m guessing you might not want to answer this yet, but figured it wouldn’t hurt to ask. Would apps like Tidal Connect and Qobuz Connect run only on the Player engine? I wonder as I can’t see much point in having a separate server app for these as I think the servers for those are actually in their respective data centers. If so, then would keeping the CPU meter for the Player still make sense?

Insightful as usual Ken 
I am going back to edit my post, from removing to redesigning
