Playback stopped because data didn`t arrived in time

[Tore]

I`m playing with 09z-8-2  and the sound is Fantastic.

But music often stops when i start playing and when i press next song. Then i get this message: 
Playback stopped because data didn`t arrived in time

Tore,

This is a new message since 0.9z-8-2 (never announced in the Release Notes) and it tells you :
Well, that all was too slow to provide the data in time for the short buffers applied (Q1 x xQ1 x Device Buffer Size).
It may happen that only once in a while it does not work.

It can happen during playback just the same.

Before (earlier versions) music just stopped and you wouldn't know why. Now you know.

Can happen only with Phase Alignment engaged.

Hope this helps ...
Peter

Hi Tore,

Does it happen when you use the Playback drive also or only when you play music directly from your music hdd?.

In my case it only happens when I play music directly from the hdd where I have the music files stored. If I play with Phase Alignment disengaged as Peter suggests there are occasional stops for a short space of time but also and more important the SQ is worse than with PA engaged. In my opinion the best SQ is with PA engaged and playing directly from the hdd where the music is stored, I mean not using any Playback drive at all (neither Galleries), but this way there are that stops. If that could be fixed using my present Q1:7 x xQ1:1 x 4096 setting that would be a step ahead in SQ.

Juan

Hi Juan!

I have just tried without Playback Drive and SFS=1 , Q1=7
It is just the same, not working. Maybe my PC is to slow?

I`m playing with SFS=4, Q1=14, that is working without stops

Hi Tore,

Yes that´s the problem, without Playback drive the stops are there, as Peter said to make it works PA needs to be disabled but at the same time that´s a shame because the SQ is worse. If your PC is slow mine is slow too because once in a while I also have that same problem. I wonder if the ones with the fastest PC have also this problem.

Hi Juan,

I am sure it will be a language problem or symantics otherwise, but no way I will have said or will ever say something like "hey dude, to make it work, just disengage Phase Alignment - Done !". No way.

I am sure you don't meant to express it like this, but again language or symantics make at least me read it like this.

So ... not using Phase Alignment will help, but no way I advise it as the solution. I hope this is clear !

Peter

Because there's too much "off topic" going on, I now don't know where I wrote it, but please read all my posts from today. One of the first from today will tell you that most probably it is not about being "slow" at all (hint : Page File thing).

And btw, as far as I am concerned your PC is not slow. Nor is mine (find that post).

Best regards,
Peter

Below is Peter's post on the possible page file issue from the Not Enough gain thread:

Don't know whether this has anything to do with anything: My amp kept tripping its safety shutdown a day or two ago when the DragonFly was set to 50% volume.  40% was OK.  I don't recall whether I'd tried the DragonFly at that volume before.  It's the first time the amp has tripped that I can recall.

Jud, looking at this again and after listening last night to a best rendered Who I ever heard before (I very regularly play Who's Next because it has always been very good for SQ) ... your problem is that of a PC/Driver combination which more people suffer from and I recall a topic from Arvind at least. But what I also recall is that he solved it, without real knowledge of how (ehm, at my side). I can't help to solve the problem, but at least I have some new information from lately ...

So, this is about "something" happening in the PC and the most logical would be something like needing to write to the page file. I saw this happening myself (your 20-30 seconds) and it looks to be related to needing more memory at a second load of a track part (per SFS boundary) and although this doesn't imply a "swap out" (it doesn't work like that from off Vista) it implies a "more memory needed" and let's say this always involves the page file. Why my focus to the page file ? well, because it receives the very highest priority of all, and it may stall everything else (when a bit in trouble so to speak).

Long story short : disable your page file just for trials.
Notice : even when disabled it will be there for a smaller portion but that is normal behavior and okay for this test.

Also, and similar to what I wrote two days or so ago, since this doesn't formally stop the stream hence I don't notice a thing of it, again this is about this real stall where all stops. It has to be, or otherwise I'd notice it. This again leads to this highest priority thing and the really only thing I know of which incurs for that *and* may take somewhat longer (and too long) is the page file I/O.

Don't try this with an SFS-Max (notice the Max) of around 400 and 8GB of internal memory only; this will choke your system sooner or not so much later.


And then about this PC/Driver combination ...
I have this PC which *needs* the "After SFS Rounds" to be set, or otherwise a crack will happen shortly after playback started. So, After SFS Rounds solves that, but it is a backdoor solution to something I don't know the cause of (better English perhaps : I have no clue what happens). Now :
This very same PC with the very same drivers and everything does NOT exhibit this with Windows 8.  It hasn't a single time, just like my normal Audio PC never exhibited it under Windows 7.

This is quite important to know, already because of, say, half of all people suffer from this (necessity to use After SFS Rounds). But obviously it is OS related, or a combination with drivers which are different for W8 somewhere under the hood (yes, I said same drivers, but for that I merely refer to mobo / video card etc. drivers). Still, this too seems to be related to some high prio stuff, because I can't find the real relation to the happening in time (after the start) and it feels like a write cache which as some stage *has* to be flushed (to disk). This will not be at the precise same time, but at some stage the OS thinks "NOW there's some free time to do it !".

I know this is in the middle of a topic about something else, so people may not read it, but *if* someone reads this, for this too he might try to shut off the Paging and see whether it helps this issue (so, switch off Paging (Virtual Memory), set After SFS Rounds to 0 and see whether the crack at a few seconds into the track now stays away).

If someone needs help on how to switch off the Paging (Virtual Memory) just let it know.

Thanks Peter and Brian, tomorrow (now is late here) I´ll disable the page file and see if it solves the problem.

Best regards,

Hi Boleary/Juanpmar,

As yet I haven't been able to solve 3 issues:
1)Playback stops. I increased the Q1 from 14 to 15 & the stopping has reduced, but I still get one stop within 10/15 mins of starting.
2) Fairly loud tick. Within 10 secs at start of a playlist, I get a fairly loud tick. Thats it & it never occurs again until I load a new playlist. 
3) Low level thump at Stop. This occurs every time I stop or when a playlist ends.

I haven't tried 0.9z-8-2 (W7) as yet simply because I am comfortable with RDC. Maybe it would solve some or all the above problems.

Best regards,

Arvind

[PeterSt]

Thank you for the feedback Arvind (but why do I have in my mind that you solved it ?).

0.9z-8-2 will not solve anything in this area, although it runs more lean so very maybe, but then indeed outside the Remote Control (or RDC as how you refer to it).

Regards,
Peter

Same problems here with that message! Indeed when you switched PA off this message disappears and music start with stuttering for the first seconds. I never hear that stuttering before at the start of a track.

Changing Q1, Q1x, SFS, Buffer,... its very difficult to find a right setting to keep PA on.

Your suggestion to disabling the page file is a solution for this time problem? In version 09z-8-1e i have sometimes a start problem but after a second start it plays.

Johan

[PeterSt]

I never hear that stuttering before at the start of a track.

Johan, you seem to talk in the context of "this is new to 0.9z-8-2". Is it that what you mean to tell ?

Peter

[JohanZ]

Indeed! 

[PeterSt]

I can't believe it.
The *message* is new. Stopping or not should be unchanged.

?

(feel free to disagree, and I'd even say "please" !)
