As you can see, jackd does start at 48KHz [2]. As you can see [3] - [5] jackd doesn't start at higher sample rates. The card can be used with higher sample rates on Windows. What am I doing wrong? Regards, Ralf PS and OT: If somebody does use this card with all 8 ADAT channels, it would be nice to send me a hdspmixer file off list, that does enable this. I never get it working for more than the first 2 ADAT channels when using TotalMix, aka hdspconf on Linux. I'm able to do it on Windows. Note, I'm not a Windows user ;), I installed it some days ago to check the card.

But I'm running apps from various user ids, which still doesn't seem to be supported with jackd, except that it *is* meant to be supported through the env var JACK_PROMISCUOUS_SERVER. Except that this doesn't seem to work (anymore? [*]). This is jackd from the Debian Wheezy package, 1.9.8~dfsg.4+20120529git007cdc37-5 I'm setting umask 0000 for both server and client, JACK_PROMISCUOUS_SERVER="" (I've also tried other values), but the client tries to open a different socket path; when I hard link the socket path to what the client expects, it segfaults. I'm considering debugging this but I'd appreciate some hints, like, do you have an idea what broke it (assuming that it's a bug that broke it), or whatever else I should know about it.

We have a playout system for audio files, where users log in one at a time and as part of their session jackd is started, along with the newly created audio player 4deckradio. When they log out, all their running programs (including jackd) are killed. Every now and then, after maybe 15, 20 new logins, jackd refuses to start for all users. The error message is that there are "too many servers already active". However, there are no jackd processes still running when I do a "ps aux | grep jack". A complete restart of the machine remedies the problem, temporarily at least. My hunch is that jackd isn't able to clean up properly sometimes (perhaps because it is killed before it has the chance?) causing future servers to not start. I'm at a loss however to figure out -what- exactly it doesn't clean up, if that is the case. Could someone shed some light on what is preventing jackd from starting up?

I had this working on a previous set of systems, but this time around... not so much. System 1: tobago$ jackd -R -d alsa -P hw:0 -C hw:1 -p 1024 tobago$ jack_load netadapter System 2: trinidad$ jackd -R -d alsa trinidad$ jack_load netmanager At this point, jackd starts printing on loop: Waiting for a slave... Error : slave is running with a different protocol tobago Can't init new net master... Unfortunately googling "slave is running with a different protocol" only yields two results other than the source code, and neither is helpful. I checked the version of jackd on each system; one is 1.9.9 with protocol 8, the other is 1.9.9.5 with protocol 8. So I'm doubtful that's the issue.

Meantime I dig a little and I think that found a reason of this issue, If you look on this line from transport.c (jack_transport example client): pos-&gt;tick += nframes * pos-&gt;ticks_per_beat * pos-&gt;beats_per_minute / (pos-&gt;frame_rate * 60); IMHO it mean "how many ticks are in current period". If nframes is 256 and frame rate is 96k and BPM is 5 (or less) you got 0.928798 ... but pos-&gt;tick is uint32_t .. so you actually got 0 ;-). OFC this is related to your settings and that's way YMMV. Well ... in some cases jack_transport will not push BBT at all ;-) The problem is in Transport design itself - because BBT master works always in current cycle space/context - I mean - it doesn't look at the history (anyway it can't if we want to have tempo changes, right ?), and because ticks are uint32_t we will have always some rounding. The most simple way to fix this that I see is push tick to double - but this</pre> Pawel 2013-05-15T04:31:20 http://comments.gmane.org/gmane.comp.audio.jackit/27368 <pre>Hi, New to the list so usual apols about addressing questions wrongly etc. I want to play around with passing Asterisk audio through Jack on Linux. I've successfully installed and configured Jack and Asterisk to talk to eachother, but the documentation for command-line style manipulation is quite light on the ground. Currently, connecting my call to the JACK() app sends 5 seconds of silence. For my first proof of concept I'd like to get it to send back some sort of sound. This is a server system so there is no GUI etc. Even if it's streaming a sound file that would be fine. After that I would like to manipulate audio with something like libfaust - wonder if anyone here has experience with that? A simple script to change the pitch of audio would be amazing to see. Thanks! Leo </pre> Leo Brown 2013-05-11T13:56:42 http://comments.gmane.org/gmane.comp.audio.jackit/27365 <pre>Hi, I discover strange problem while improving JackTransport support in FSTHost. Most VST plugins while trying to synchronize with host usually ask for such things: 1) tempo ( == jack_pos.beats_per_minute) 2) ppqPos - which I understand like "current quarter note" == current jack_pos.beat. 3) barStartPos .. ok, this one is not a subject in this case ;-) 4) samplePos == jack_pos.frame 5) sampleRate == jack_pos.frame_rate The problem is which pppPos. There are two ideas how to compute this: 1) Using BBT (which should be a preferred option here, right ?) double ppqBar = (jp.bar - 1) * jp.beats_per_bar; double ppqBeat = jp.beat - 1; double ppqTick = (double) jp.tick / jp.ticks_per_beat; ppqPos = ppqBar + ppqBeat + ppqTick; 2) Using sample rate / current frame / tempo - this is a standard way in VST world. We count how much samples is in quarter note (beat) .. double ppq = jp.frame_rate * 60 / jp.beats_per_minute; ppqPos = jp.frame / ppq; The problem is that .. this second counter "hurry" (sorry can't</pre> Pawel 2013-05-09T01:22:53 http://comments.gmane.org/gmane.comp.audio.jackit/27358 <pre>Hello, I am using jack in an application where I need sample accurate synchronization between capture and playback. I am using jack_delay and jack_iodelay to precisely measure the roundtrip latency in frames. On my better machine (core i7, maudio delta 66, 64-bit Debian, jackdmp 1.9.9) the latency in frames reported by jack_delay or jack_iodelay increases slowly over time by up to 12 frames. For example, it will start at 3132.66 frames but after ~5 minutes, it will jump up to 3133.66 frames. This will continue until about 3144.66 frames is reached and then it may return back to 3132.66 or 3.133.66 frames latency. It may take hours for it to go through this cycle. If I restart jack_delay, it does not go back to 3132.66 frames, but continues with whatever the last delay I saw was. There are seldom xruns or other errors produced during a jump. It happens at various frames/period and periods/buffer settings. It happens at whatever CPU governor setting I use (performance, on demand). It happens whether or not I </pre> Steve Haynal 2013-05-07T05:16:24 http://comments.gmane.org/gmane.comp.audio.jackit/27357 <pre>Hi, This is indirectly related to the discussion on jack an Picuntu / Android stick discussion...

I've tried to get Jack to run on this rk3066 arm hf computer without success for a while now. I posted some of the weird error messages on this list but nothing got solved. So, I'd like to ask a more general question:   Developers, is anyone working on or even interested in getting Jack to run on an arm cortex a9 platform? What are possible problems?   In my opinion, these cheap little sticks and tablets could be a wonderful platform for creating audio fx boxes, sound installations etc. They are so much more powerful than, e.g., the raspberry pi which is not much cheaper and has a much weaker cpu and ram.   I don't have much money but I would pay anyone who manages to get jack to run with an usb interface on a UG802 or similar computer. I'm sure there are others interested in this as well.   Looking forward to answers, Axel --- Alle Postfächer an einem Ort. Jetzt wechseln und E-Mail-Adresse mitnehmen!

I have started seeing crashes from the clients in the JackError() call. The stack trace shows that the thread executing (Which is handling the JackSocketChannel::Execute call) receives is being killed (sigcancel_handler is called) and since the thread is in CANCEL_ASYNCHRONOUS mode, it crashes since an unsafe function is called (vnsprintf). The client I am using is actually unaware of using Jack at all, it is using the alsa jack plugin, and it opens/closes the alsa devices many times during its lifetime. Now, I have a few doubts: - Why are threads created with cancellation type PTHREAD_CANCEL_ASYNCHRONOUS? Is this because the realtime threads need this or is there some other reason? - Would it be possible to mark the threads used by the JackMessageBuffer and JackSocketClientChannel as PTHREAD_CANCEL_DELAYED instead? - Why is fThread.Kill() used in JackSocketClientChannel::Stop instead of fThread.Stop()?
