Hi Jeppi,

Hi Dan,

Iohannes solution (change "use callbacks" state) seems to solve the 
problem. Anyway, I can open an issue to describe that in my case DSP 
only works with callbacks on.


Thanks for the answer and instructions,

Yeah, this makes the most sense: try the user value, if it's too low, then use 
the hardware value and print a notice. At the very least, Pd will keep working. 
:) I do something similar in a work project that uses Portaudio and CoreAudio.

I think the bug report isn't needed, thanks.

Meanwhile, yes, it would be appropriate to print a message that the delay
got reset, and yes, please do throw it in the develop PR.

As it looks like you guys are working on a quick and simple solution, I'll
wait a bit to see if it's really necessary to file a bug. If it's still
relevant, I can do it later.

Of course, now the displayed settings doesn't always reflect the setting used

We could post a little notice that the delay setting has been capped. 
Probably also for the ASIO backend. But that's just cosmetics.

Re: [PD] Pd 0.52-1 - frozen dsp and gui in ubuntu 20.04

[Christof Ressi]

Actually, I just remember that I fixed a very similar issue with the 
ASIO backend. However, it was a bit more nasty, because Pd would simply 
crash if the "Delay" value was too low :-) My solution was too simply 
cap the value at the hardware blocksize:


https://github.com/pure-data/pure-data/blob/3ae0388c2ba354e2b5d818c1422b7484c4a491bf/src/s_audio.c#L357

---

The problem with the Jack backend is that it caps at *Pd's* blocksize 
(64 samples) - which is often lower than the Jack buffersize. 
Consequently, the Jack callback might never have a chance to fill the 
ring buffer.


I think the solution is simple:

In /jack_open_audio()/ replace

if (advance_samples < DEFDACBLKSIZE)
advance_samples = DEFDACBLKSIZE;

with

if (advance_samples < jack_blocksize)
advance_samples = jack_blocksize;

@Roman: can you give this a try?

   Yes, please! The Jack backend is supposed to work regardless of
the
"callback" setting.

But not regardless of the "delay (ms)" setting. If it is too low,
Pd
won't process audio. I don't know if there is a way to know
beforehand
what 'too low' is. It isn't necessarily a bug in Pd, I'd say.

it's probably a bug in Pd if the DSP and the GUI both freeze.

Indeed, if the buffer is set too small, then Pd GUI freezes!

 From my anecdotal testing, it looks like the critical value is
predictable. As Christof said, the buffer cannot be smaller than JACK's
blocksize.

For instance with JACK @ 256 samples @ 44.1kHz (5.8ms):
   - Pd works with 6ms
   - Pd freezes with 5ms

I guess the dialog could be designed in a way to set a lower boundary
that is dependent on the detected JACK blocksize. I don't know,
however, if Pd is able to detect the blocksize before DSP is turned on.

little!

You're right! I was using a 10ms delay with 512 buffer size / 3 periods on
Jack.
As soon as I changed to 12ms DSP worked normally. I used 10ms on Pd for a
long time, but it was ignored as you said, and now it has turned into my
"problem".

So, that is not a bug, but maybe this limit should be clearly stated
somewhere to avoid confusion.

Thank you all so much!

it's probably a bug in Pd if the DSP and the GUI both freeze.
(e.g. a solution as suggested by christof is to ensure the value is sane 
- at least if we have some possibility to determine that beforehand)

This might actually explain the issue!

@Bruno: what is you current value of "Delay" in the audio settings and 
what is your Jack buffer size?


Actually, before Pd 0.52, the polling scheduler did not really work 
correctly together with the Jack backend, i.e. the "Delay" setting was 
basically ignored and it just did double buffering. This has been fixed.


Anyway, Pd should make sure that "Delay" is not smaller than the Jack 
buffer size, thus preventing silent output. If that's not the case, 
please file a bug report!

But not regardless of the "delay (ms)" setting. If it is too low, Pd
won't process audio. I don't know if there is a way to know beforehand
what 'too low' is. It isn't necessarily a bug in Pd, I'd say.

From what I understand, using callbacks means that Pd processes audio
as soon as it is provided by JACK. This means, Pd doesn't add
additional latency as JACK client. But it also means, that when Pd
isn't quick enought with writing back processed data, the whole JACK
process with all clients experiences a drop-out.

Without callbacks, Pd is less tightly coupled to JACK and uses a
ringbuffer for input and output. The size of the ringbuffer is set in
the 'delay(ms)' setting in the audio settings. From my experience,
setting it too low causes Pd to not process audio at all. In my
experience, this value is below 5ms, but this probably depends on
JACK's blocksize setting.

Yes, please! The Jack backend is supposed to work regardless of the

Re: [PD] Pd 0.52-1 - frozen dsp and gui in ubuntu 20.04

[Christof Ressi]

Could you (or someone) explain briefly what this is for? 
If "callbacks" is ON, Pd runs directly in the audio callback. This gives 
you lower latencies, but less "leeway" for CPU fluctuations - unless you 
increase the hardware/jack buffer size accordingly.


If "callbacks" is OFF, Pd uses a polling scheduler which runs 
independently from the audio callback and exchanges audio via a 
(lock-free) ringbuffer. This ringbuffer essentially adds some extra 
latency, so that Pd is allowed to "fall behind", as long as it can catch 
up again. You can control the latency with the "Delay" setting, 
independently from the actual hardware/jack buffer size, which can be 
quite useful.


As a rule of thumb: don't use "callbacks" unless you *know* that you 
need it :-)

Yes, I know, but there's no info about the problem, that's the main reason
I came to ask here (for the first time in 10 years using Pd, btw).

On the jackd side: Are you getting any messages from jackd, for example
> by looking at qjackctl's "Messages"?

I see nothing special from jackd side, looks like everything is working
properly, and Pd shows up in patchbays like qjackctl and catia. Starting
jackd via terminal with -v(erbose) and comparing 0.51.4 (audio ok) and
0.52.1 (no audio) the output looks the same.

And do you have a second alternative sound card you could try?
>

Not now, but it doesn't seem it will make a difference in this case. When I
have my other sound card in the next few days I'll try again.

Do you think it's worth opening an issue on pd's github?

Thank you for the support,

Cheers

But great that you tried it and hence gathered more information about your
problem. You know that you can increase Pd's debugging level and/or
start it with the -verbose flag to get more detailed error messages.
Does Pd post anything there when you start DSP?

by looking at qjackctl's "Messages"?

Yes, 0.50.2 works normally, as any other version I compiled previous to
0.52-0

Bruno, which version of Pd is available on Ubuntu via the apt package
manager? On Debian it is 

 $ apt --all-versions list puredata
 Listing... Done
 puredata/bullseye-backports,bullseye-backports,now 0.52.1+ds0-1~bpo11+1 all 
[installed]
 puredata/stable,stable 0.51.4-1 all
 puredata/oldstable,oldstable 0.49.0-3 all

Any reason you want to compile it yourself?

Does it work when you specify
 $ pd -nosound
?
Does it work with a different audio driver architecture, eg. alsa?

Does a pd (any version) installed via apt work?

and so on and so forth... ;)

[PD] Pd 0.52-1 - frozen dsp and gui in ubuntu 20.04

[Bruno Rohde]

Hi friends,

I have a problem running Pd 0.52-1 on Ubuntu Studio 20.04 using Jack. I
compile the project the same way I always did, but in this version the DSP
doesn't work (Test Audio and Midi), and the GUI partially works (on other
patches). The last version I can run normally is 0.51.4 (0.52-0 tests
didn't work either). Running Pd with the -verbose flag does not show any
relevant information. I also didn't find similar reports here on the list
and on the net.

(system info)
$ uname -a
Linux brunorohde-desktop 5.13.0-35-lowlatency #40~20.04.1-Ubuntu SMP
PREEMPT Mon Mar 7 10:14:12 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

(compilation)
./autogen.sh
./configure --enable-jack
./make

Does anyone have any information about this problem? Any tips on how to
investigate the cause and solution for it?

Thanks

Bruno
