I presume the gaps caused by changing resolution appear at the start of tracks?
The gaps that I experienced all occurred in the middle of tracks and I think only when the USB HDD was connected to the lower USB output. This may have been coincidence but after the problem appeared I tried both ports and the problem only occurred on the lower port. The music also stopped completely a couple of times during playback after music had been playing for some time on the upper port - very annoying. Aurender support were responsive but couldn't come up with an explanation for the gaps. (I have Netgear gigabit switches but as I was using USB assume this is not relevant)
The gaps my dealer and another customer experienced happened when streaming DSD files from Synology NASs and were fixed, in my dealers case at least, by his changing from a Netgear 10/100 switch to a TP-Link gigabit switch (following a recommendation from Aurender). This seems odd to me as 10/100 should be plenty fast enough?
I was told that Aurender had introduced the N100H model because so many people had had problems setting up their NASs and AMM to work with the N100.

I thought the internal SSD is present to avoid just that, hick-ups during playing. That would mean music from a USB drive isn't buffered to the SSD. Could the hard-drive have been spun down in sleep mode?
I only have a few DSD files, but I've not had gaps in playback with any of them either. Also streamed from a Synology NAS, I do however have a gigabit Ethernet. Again weird that a DSD file apparently is not buffered on the SSD.
I really never had problems with using AMM. I think it's pretty straight forward. I did contact Aurender Support to ask about some files which generate a fail. Support told me there will be a better fault log in the future.
That's what confuses me - the playback gaps that I had all occurred with multiple tracks, usually whole albums, in the playlist and I had thought the files would all be in the cache... Otherwise what's the point of having it? I will check sleep mode on my HDD but it's played for hours with no issues.

true
but if playlist is big enough or if you keep hopping from one album to the other, the buffer SSD will be full before you know it especially with hi-res big files. accordingly the system will keep on flushing and re-buffering to the SSD. and it could be that this is not smooth with externally connected HDD as it is with the built in HDD in case of X100 or N100H

That's something worth trying. I've never had the SSD buffer full. I wonder what'll happen.
I've never had more than a single album in a playlist so even at 24/96 that should only be say 1.5Gb against a 120Gb cache. I always cleared the playlist between albums.

but remember that the system will not flush the buffer of previous sessions on the assumption that you may want to play those tracks again and there and then they will be ready for you. so while a single session is not enough to load ur buffer SSD but it is already loaded from previous sessions
a simple way to test this theory is to play one album in full, this way you ensure that it is fully bloaded and uffered to the SSD, then try to replay it again. if my theory is valid then you should not experince any hiccups in the replay as it will ideally be playing from the SSD

I think clearing the playlist (with the clear button) does flush the SSD cache. If I don't clear the playlist and powercycle my N100 the playlist is still ready in the conductor app.
Does anyone know if the complete album is loaded onto the SSD or does it load a track at a time. My point is that if it loads the album in it entirety then i would suspect that only the first few tracks would have an issue playing if it is having trouble loading the files.
Hi Phil, i can't say i really noticed when i had the unit at which points it dropped out

Oh, ok, that's interesting
Though if that's what's causing gaps in playback in the middle of a track then it's clearly a design flaw. What happens is that part of the way into a track there's a gap, then it plays ok for maybe a minute or so then there's another gap and another and so on and there are gaps in the following tracks too.
Since I've been using the top USB port exclusively - probably 5-6hrs+ playback from USB and Tidal - I've had no problems apart from one unexplained stop.
