What type os Raspberry Pi is this (what generation) and what file format are you playing? Generally, sync between different player types works but it's a question of timing. Not so much computing power but the exactness of the timing on the player. Where you need computing power is on the server side. Older RPis had very bad timing behavior, that can cause some trouble but newer ones usually work OK. What can make things more difficult is also if the different players support different file formats, if one of them doesn't support something then the server needs to start transcoding. iPeng's limits are that it doesn't support sample rates beyond 96kHz, currently no OGG/Vorbis (because that causes issues with Spotify) and iPeng uses a bigger buffer than other players which can under certain circumstances confuse the server. For the latter, iPeng has a configuration setting in the playback settings. One other thing that often causes trouble is if you stream raw WAV/PCM for lossless formats instead of FLAC (which is the default in LMS). iPeng throws that data directly at iOS but iOS sometimes guesses the sample rate wrong and that can cause all kind of weird effects. If you set your server to transcode to WAV or PCM I'd recommend against that. That's pretty much all I can think of right now in terms of problems. --- learn more about iPeng, the iPhone and iPad remote for the Squeezebox and Logitech UE Smart Radio as well as iPeng Party, the free Party-App, at penguinlovesmusic.com *New: iPeng 9, the Universal App for iPhone, iPad and Apple Watch* ------------------------------------------------------------------------ pippin's Profile: http://forums.slimdevices.com/member.php?userid=13777 View this thread: http://forums.slimdevices.com/showthread.php?t=51929
