Swapped out my Topping D10s DAC (audio path = Roon on M1 Mac Mini, files on Synology DS 918+, endpoint = Raspberry Pi 4 running RoPieee (latest version) which is then hooked up to the DAC) for a Focusrite Scarlett 18i20
The Topping was perfect apart from not having headphone output so as I’ve had the Scarlett spare, I’ve popped it in place hooked up via USB (A on the RasPi to C on the Scarlett), but I get really low level crackling, like ultra-low vinyl crackle.
I’ve tried USB 2 and 3 outs from the RasPi, but both are the same. Clock is set to internal on Scarlett.
Shame - really spoils some of my fav tracks by Nils Frahm etc. I suppose there’s a reason why Focusrite Scarlett is cheap. My RME ADI2 DAC is fine in another listening location. Might have to get rid of the Scarlett.
Don’t know if it’s related, but had faint irregular tick sounds after a certain Ropieee update about half a year ago with wireless and wired connections, which Harry couldn’t reproduce.
Switched to DiePi with Roon bridge and problem was gone on both RPi3b+and RPi4b connecting via USB to a SMSL M300Mk2.
Give it a shot with Diet-Pi and see if it goes away, nothing to lose really!
Good info both - thanks muchly. I’ll have a go with DietPi and also others if no joy - it’s only the time to re-flash a card I suppose. Trouble with intermittent faults is that developers are really pushed to get to the bottom of a solution.
Interesting you mention MotU - I’ve got an M4 in transit from Thomann as we speak. Can’t get hold of an Ultralite Mk5 for months it seems. Also got a lovely old 828 Mk2, but it’s FW800 input just isn’t practical to use in the same way.
Multichannel isn’t something that’s of great importance just now but it’d be good to have enough outs on an interface for future proofing.
The worldwide chip shortage is a pain at the moment though for the purchasers of interfaces and DACs. I’ve had the M4 on order for 2 months and I see that the new ADI2 DACs have adopted new chips due to AK being unavailable.
