I also play back from SMB over WiFi and Ethernet. I don’t think it’s solely a WiFi & SMB issue since I am getting the same behavior that you describe over Ethernet. There’s no bottleneck on my wireless network. I’ve played with buffer settings, but they don’t fix the problem nor do I see any improvements.
My 2 instances are running music via USB and smb share / online stream.
They are stopping at no specific point.
I also got a strange behavior today.
It says it played the four minute track fur over 1329 minutes…
I started this playback after redeploying the system and did not take a further look until now. 
Just FYI you can install the ympd MPD web client on the RPi , it will run concurrently with the volumio web server and will be reachable at ‘volumio.local:8080’. In my tests I have not had the playlist stopping problem using this.
I would like to try that.
Could you give me a hint, how the package is named?
Currently I just can find this:
mpd - Music Player Daemon
libmpdclient2 - client library for the Music Player Daemon
upmpdcli - UPnP Media Renderer front-end to MPD, the Music Player Daemon
mpc - command-line tool to interface MPD
libupnpp3 - C++ layer over libupnp.

OK, got it… 
thought it was in the sources.
I started the Playback through ympd…
Lets see if this helps.
I think you have to install it from the command line , I’m not sure how to get a package. If you are using windows i think you need to install ‘putty’ to use ssh to interact with volumio.
ssh logons to volumio have to be enabled from the dev menu ‘http://volumio.local/dev/’
After that you can DL the ‘ARMv6 Hardfloat’ version , from https://www.ympd.org/#downloads decompress the bzip file and copy the binary to volumio.
Then you can log in to volumio with ssh and run it with ‘./ympd --webport 8080 &’
Then you can connect to it from a web browser with ‘volumio.local:8080’
Another oddity that I just remembered and that surfaced about the same time as the playback issue came up is that navigating Volumio through the GUI is sluggish (i.e. the thin green progress bar that displays at the top to show the progress is slow and pages load slowly). Not sure, if it’s related. Anybody else gets this?
Hi,
So, was it help to fix this issue ?
Hi,
it is a workaround.
Not a fix / solution.

I think I found a solution for this problem. See https://volumio.org/forum/possible-bug-statemachine-increaseplaybacktimer-t11921.html. I patched my local copy of volumio and haven’t had any stopped playlists since. I ran a 48hr long playlist to test it. I suspect that this bug may only effect older slower hardware which is why its not a common problem. I’m running volumio on a RPiB+ , i belive this is below volumios recommended hardware requirements at this point , but its working fine for local files , webradio and airplay. I’m not using any plugins at the moment.
Same for me. I confirm that applying this patch solved the issue of unwanted pauses between tracks. Thanks a million!
I have a recent HW (RPI3 B+) + Volumio 2.513, and this bug appeared for me quite often when I updated the database in background (copy files via rsync and then “mpc update”). So, it’s not only related to old HW, it depends on the global load of the system. If I listened to music without updating, I did not have the issue.
But after the patch, I can update while listening to music, without any issue.
I can indeed confirm DK31’s expirience with this bug. I myself have two RPIs (3b+ & 0W) both running the latest and greatest firmware (v2.575). If I make them sweat then playback stops. I’ve since implemented the hinted fix (github.com/volumio/Volumio2/com … 6148c8f045) and both RPIs now run as they did before the update, no matter the load. Visual playback timer stops showing time left once in a while, but that’s about the only drawback i’ve expirienced the last 4 days.
