For a while I have been using a LMS system (Daphile on a rather low-end Via system) with 2 players that I usually have in sync. This works well.
But if I do the same with Max2Play on an rPi 2, I get dropouts about every 10-20 seconds. Until I stop syncing, or turn one player off. Then it plays smoothly! I have the latest updates installed.
Any ideas?7. September 2015 at 15:55 #15639
This problem can have many different sources. It can be because of your WiFi signal, your power supply, your music files. Please try to eliminate the sources of error first, by changing location of the Pi’s, trying a different power supply and using different, lower quality music.
Also, if you do not already, please try and run LMS on one of the Max2Play devices.7. September 2015 at 16:06 #15640
Thank you for your response. I experimented a lot with moving the devices around, connecting both wired and wireless but nothing made any difference. However I am not sure if I tried local files, I usually use it for radio and Spotify.
Regarding your last remark, it is the LMS on Max2Play that causes the trouble, independent of what kind of players I use (Squeezebox Classic, PiCorePlayer, Max2Play…). Now that I am using the LMS of my Daphile again, all problems have vanished.
And remember: the trouble starts when I use more than one player at the same time. It seems this is too much load for the LMS on Max2Play, although the web interface is very responsive!7. September 2015 at 16:38 #15641
Usually, the Pi can manage multiple players in our setups with any problems. Did you maybe forget to expand the filesystem before installing LMS? Than you would have over 80 percent of your memory used which is displayed in the debug info on Settings/Reboot. This could also be a problem factor.7. September 2015 at 19:33 #15643

The log does not indicate anything going wrong. Your system seems to be running perfectly. We can only recommend using the newest edition of Raspberry Pi, Model 2B, if you do not already. Otherwise there is nothing else to fix.3. Februar 2016 at 22:36 #18377
I’m having a very similar problem:
– Raspberry Pi 2 Model B
– Fresh M2P install with JiveLite
– Sound output via HDMI
– LMS running on a different machine, no problems with any of the other clients
– I’m NOT using synced playback.
With this setup, I have sound dropouts as described by hanszorn. The M2P machine has a filesystem expanded to 8GB and CPU load is typically below 5%. HW codecs are activated (which should not make a difference 😉 ). When I take the headphone jack, the dropouts do NOT occur. Well, waiting for my HifiBerry DAC+ and hoping, that there will neither be any dropouts.
Nevertheless, it would be nice if you could assist in solving this issue.
Thanks!18. Februar 2016 at 14:37 #18573
There are a few things you can try to fix the issue. The DAC+ will work great anyways. In your current setup, however, with the HDMI output, the Pi should be the issue. Please check if you have Kodi on or on autostart, test it with just Jivelite and Squeezelite running. Also, please try connecting the Pi to another device like a TV via HDMI to rule out the port as the origin of error.
If you have another Raspberry, please try it with the image you are using on the one with drop-outs.18. Februar 2016 at 16:14 #18584
thanks a lot for your reply!
I already tried around a little, and with the same hardware, running a Volumio image, I have no trouble at all. So I would say, the problem should neither be the hardware, nor the connection between the Pi and the TV. Additionally, Kodi is turned off in my setup.
So I would really guess that it is a configuration problem of the Max2Play image.
If you have any further suggestions or an opinion different from mine, please let me know 😉
Nevertheless you’re quite right: The Pi-DAC+-combo works great!
