Re: [SlimDevices: SqueezeCenter] Out of sync playback - PC & 2 androids

It also depends on the hardware/OS.
I think on Android it depends on the Android device. Some have
deterministic audio drivers and there sync should work fine, others
don't. Stefan, the author of SqueezePlayer has written about it
somewhere.

I think Windows never works because it doesn't have a deterministic
audio driver.

Linux is often better, iOS should always work, OSX: I don't know.

The biggest problem is if the audio driver buffers audio data for an
undefined time. Windows does this because that way it can decouple the
output timing from the application timing. There are special,
deterministic audio drivers for Windows but I don't know whether they
are supported by SqueezePlay, chances are probably better with
SqueezeLite but I also don't know for which sound cards they are
available.

- Syncing original slimdevices/logitech Hardware on a "good working
  net" is always running fine.
- Syncing same Software Players on same Hardware is often fine.
- Syncing different Software Players even on same Hardware is a mess
- Syncing Software Players with unequal Hardware is sometimes "good"
  mostly a big mess.
- Syncing different Software Players with unequal Hardware is a big
  mess.

Sure, but afaik the players have to report back where they are in the
playback. And if they do this unreliably then the server has a hard time
keeping them in sync.

Ah, yes, the out of sync playback is not consistent, and sometimes
drifts... I would have thought the whole point of the media server is to
provide a clock to consistently sync with?

Hi there,
I have not tried fiddling with those settings... are there any you could
recommend, I see there is 

Synchronize Volume
Synchronize Power
Maintain Synchronization
Player Start Delay (ms)
Player Audio Delay (ms)
Minimum Synchronization Adjustment (ms)
Network Packet Latency (ms)

tx

Did you try to adjust the player specific sync settings in LMS
WebUI->Settings->Player tab?
But this might be of no help if the experienced delays are too random.

[SlimDevices: SqueezeCenter] Out of sync playback - PC & 2 androids

2016-10-01 Thread fredphoesh

Hello all,
I'm a bit of a newbie to this. I have searched but have not found any
answer I can understand.

I have a 
PC running Logitech Media Server (Audio out via USB) playback with
SqueezePlay app
Android TV (Nvidia Shield) running Squeeze Player (Audio out via USB)
Android phone Note7 running Squeeze Player (minijack output)

Playback happens simultaneously, all are controlled via the LMServer but
is never properly in sync. I have unsynced and resynced all the devices,
in various orders, several times... but to no avail, it is still not
working properly.

Sometimes the sync is as much as a second or two out, usually half a
second or so. They are all out, it is not like any two of my 3 devices
can be synced either, they are out of sync. 

Is there something I am not doing that is causing this, or is this
"normal"?

Thanks,
Mark.
