Well, tried installing Dimension 4, no effect apart from making the RSS
ticker on the SB3 pause every time Dimension 4 updates the time! I set
it to 45 seconds. Same sync problems, sometimes I can correct them by
rebooting PC/SB3/Boom, sometimes not.
So I'm off to some hardware forums to see
It is not the wrong time of day that is the issue, but the rate of
change of that time of day.
The synchronization process works by calculating, every second, the
-apparent- start time of the track for each player, based on the report
from each player of amount of the track that has been played
Ah, I see. Sadly almost impossible to Google for more information on
how to correct, if indeed I can, as CPU clock speed is all that turns
up.
Does anyone have any links for further reading?

Thanks awy. Some Googling found this
http://support.microsoft.com/kb/314054 from MS - is that the sort of
thing I'm after?
Just checked and WinXP system time is set to update from
time.windows.com but if I attempt an update I get sync failed. So it
looks like this could be worth pursuing!

I don't really know how this stuff works under Windows.
The main issue seems to be that your server clock does not seem to run
at the correct rate.
Under Linux, there is a mechanism whereby an NTP daemon can detect this
and use a kernel mechanism to adjust for it. This is separate to the use
of
Pardon my ignorance, but we're not talking about CPU clock speed here,

I can't recommend this NTP server enough:
http://www.meinberg.de/english/sw/ntp.htm
It disables the (crappy) windows time service, sets up a port of the
real NTP, and its own user, and comes with a great list of pre-defined
server pools.

It looks like your server cannot keep time. This is a requirement for
successful sync. The clue is the following:

I've had two SB3s for ages, one wired, one wireless. Have never had
*any* sync issues at all, ever, under any version of SqzCtr.
Now, having added a wireless Boom, sync is awful. Using LAME to go to
192kbps from apple lossless, always have done to the wireless SB3. Up
to three seconds out,
The Boom is only a few weeks old, so it can always go back as
unsuitable.
Oh, and I'd try contacting Support, but they've never responded to me
yet, so I'll save the RSI...
I realise I'm moaning, but I just want to listen to some music.

What kind of server do you use?
Do I understand correctly that you transcode to mp3 on the fly? Why?
Please try to transcode to flac instead, should use much less CPU and
give you better quality at the same time.
I think your sync issue could be due to the server simply having too
much load.
I'd first try (temporarily) a couple of simple Boom tests to rule out
WiFi issues:
- move Boom much closer to your router
- try wiring Boom (arrow back to setup, select Ethernet)

Many use a free program called NetStumbler to see the various WiFi's
around them which may be causing interference.
Haphazardly picking different WiFi Ch's is as good as rolling dice to
pick your WiFi Ch.

Please try turning off mp3 transcoding. You won't extend anything
through that any WiFi coverage will be good enough for a single flac
stream.
Scheduling on windows isn't particularly good and while transcoding to
mp3 will not bring your server down it can be enough to kill sync
timing.

And also you are doing both mp3 trans-coding and flac trans-coding
simultaneously, it must make life harder for the sync algorithm ?

Yes, I understand that. I just thought that if you sync players it uses
the smallest common denominator for all of them. For example, if I sync

the Touch can play AAC natively because otherwise sync would not work.

So, now streaming in flac. Changed router to switch it to G only.
Changed channel to 9. At the moment, that's an arbitary guess, yet to

But, when time permits, I'd still spend 20 minutes investigating your
