View Full Version : Synchronisation issues with local stream (DAB radio)

I have sync problems when playing a local stream from DABBAR, but not with stored music or internet radio (inc Alien BBC). I am running Slimserver 6.1 (nightly of 18.5) on Windows 2000 with 1 x SB1 (wireless), 1 x SBG (wireless), 2 x SB2 (wired), 1 x SB2 (wireless). Synch quality is very good using stored music, acceptable using internet radio streams, and unacceptable using DAB radio - the worst offenders are the SB1 and SBG which are about a quarter of a sec out of synch creating a real echo effect.

Has anyone got any ideas about this? I looked up 'synch' in the forum and the bug list but didn't see anything similar.

I have the same problem between a SliMP3 and a SBG. I think it's
unavoidable due to different buffer sizes, and I plan to upgrade both to
SB2s as soon as the money tree blooms.

What bugs me is that it works fine between all three types of SB on my system for all but one type of source. It seems to me that there must be a clue in that somewhere.

- thinking aloud then ............

My recorded music (syncs fine) is all FLAC, and gets converted to MP3 for my SBG and to WAV for my SB1 (v good signal), whilst the SB2s get direct FLAC transmission. Internet radio sources are all streamed in MP3, which I think is true for Alien BBC (after conversion by mplayer).

The source I have problems with is DAB radio, which I think streams to slimserver in MP2 and this is passed onto all the flavours of SB as MP2 (48kHz) - someone please contradict me if I've got this wrong. So is the sync just not setup to handle Mp2 or maybe the 48kHz stream?

Can I set slimserver to convert MP2 to MP3 (setting in convert.conf?) to test this theory?
