Re: [slim] Synchronisation problems squeezebox and squeezebox2
It has stayed in sync for a nearly a whole day now. I have been doing some reading up on VMs and time keeping is a known problem. They tend to drop interrupts and hence the time can drift, the recommendation seems to be to ensure they sync with a time server regularly (which I have done now). My SB2 had lost quite a lot of time relative to the server (~20s) and if it only goes forward in 5ms steps that might explain why it never caught up. In an early post you will see I thought the 7.3 upgrade fixed it, I suspect it was actually the fact that 7.3 upgraded the SB2 firmware and hence it did a resync. I appreciate that I might be in a minority by using a VM but would it be possible to allow the SB to reset its time at other times, for example at power on?

Re: [slim] Synchronisation problems squeezebox and squeezebox2
Unlikely. The clocks in the S2s are generally very stable. More likely that the server clock is drifting; perhaps there is a problem with it running in a VM. The adjustment mechanism, by which SC tracks relative drift between the SC server clock and the player clock, is deliberately slow, so as to avoid big jumps due to short-term network congestion and similar effects. Actually it is slow only in one direction: the biggest positive adjustment you will see is +5ms, while it will jump as much as necessary in the other direction, on the basis that network latency cannot be negative :-). So, if you reset the SC server clock, it is probably necessary to force the player to reconnect, either by rebooting it, going through the network connection dialogue again, or disconnecting the network link long enough for the connection to fail. Once you got it in sync, did it stay in sync for an extended period -- awy awy's Profile: http://forums.slimdevices.com/member.php?userid=7480 View this thread: http://forums.slimdevices.com/showthread.php?t=58797 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Re: [slim] Synchronisation problems squeezebox and squeezebox2
awy - I have used many versions right from the early days but prior to 7.2 it was 7.1. Interesting about the clock, my server is actually Windows 2003 VM (VMware server is the host) and I have set the option to sync the time from the host but I am going to try letting it free run and sync with my time server. The DHCP config gives out this server and may be being used by the squeezeboxes but not the VM host (the VM host is not the time server).

They don't really get time from anywhere. They have a free running 1kHZ clock (jiffies) that starts at 0 on boot. SC tracks the jiffies epoch relative it its time.

The problem definitely seems to be time related. I reset the server so it was at the correct time but it took a while before the time on the squeezebox2 matched (the squeezebox seemed to be ok). Once the times matched then playing a track was perfectly in sync.

That is interesting, I was starting to wonder if it was just my set up. I am fairly sure this is a new problem that only start happening with 7.2 release - have you noticed it before? It does appear to be a recent problem. Previously synching SB2 to Duet worked OK with my setup. However, I don't use the sync much. My new Boom arrived Saturday; so in setting it up I tested the sync to an SB2 and was suprised at the lag. Happy to capture logs for comparison when I get a moment at home, if that would be helpful.

Re: [slim] Synchronisation problems squeezebox and squeezebox2
Neil, what version of SC were you running before 7.2? Thanks for the log. It is interesting. I appears to show a discrepancy between you server's clock and SC's idea of the player's clock. The series of adjust jiffies epoch messages shows an unusual pattern. There is not a long enough period covered in the log to be sure, but is appears to show that your server's clock is drifting at quite a rate, occasionally being reset. What operating system and hardware are you using? If you could get another log, also with network.protocol.slimproto=debug added to the mix, that might help to narrow it down a bit. Also, if you could stand leaving it to play a bit longer out of sync, perhaps across a couple of track changes, without manually changing things then that would enable me to see some more context. -- awy awy's Profile: http://forums.slimdevices.com/member.php?userid=7480 View this thread: http://forums.slimdevices.com/showthread.php?t=58797 ___ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Do you have any mp3's that you could try just for diagnostic purposes? This might help pinpoint whether or not the sync issue is due to a difference in streaming format or transcoding that needs to happen for your SB1. The SB1 and SB2 will both play back MP3 natively.

Re: [slim] Synchronisation problems squeezebox and squeezebox2
I have tried it with an MP3 and disabled FLAC (which I think means they both use WAV). With the MP3 I just tried, I hear the squeezebox start then 13s later I hear audio from the squeezebox2 but both displays show the same time, i.e. the squeezebox2 says it is 13s in to the track before I hear anything. If I unsync or turn off the squeezebox the squeezebox2 behaves correctly - it starts playing immediately.

The Squeezebox (SB1) has no hardware decoder for FLAC while the SB2 does. So your SB1s are definitely playing a signal transcoded by Squeezecenter.

It could be due to the transcoding that is required though for your case. 7.3.2 fixed several sync and transcoding bugs I believe, so you might give that a shot. Otherwise, check the Synchonize settings for each player in the web interface and make sure that none of them have odd values for: Player Start Delay (0=default) Player Audio Delay (0=default) Minimum Synchronization Adjustment (30=default, maybe) Network Packet Latency (2=default, maybe) Note that these settings are on a per-player basis so check all your players.

Great news. The original Squeezebox rev 1 cannot play FLAC directly and the FLAC will be decoded to PCM (or wav?) and then streamed. I think you're just conflating the file format with the stream format. The file format is the format of the actual file being played, not the in-transit representation.
