[Jack-Devel] Cannot combine audio devices with more than 64 channels

by Jörg Müller

I need to combine two HDSPe MADI FX cards to one virtual device. I have a working driver, which is alsa-compatible. I can select each single card in any alsa-compatible application and all channels work flawless. For combining the MADI FX cards to one virtual device, I created an .asoundrc with 194 inputs for each card. When I start that virtual device via jackd -R -d alsa -C madifx_record_all -P madifx_playback_all I get this error: > creating alsa driver ... > madifx_playback_all|madifx_record_all|1024|2|48000|0|0|nomon|swmeter|-|32bit > jackd: pcm_multi.c:1060: snd_pcm_multi_open: Assertion `!slave_map[sidxs[i]][schannels[i]]' failed. However, it works when I reduce the amount from 194 to 64 channels per card. I tried to use 128 channels per card, but that fails the same way. See my alsa-info attached, which also includes the .asoundrc content. I also found this, which might be related: https://ccrma.stanford.edu/mirrors/lalists/lad/2005/06/0202.html To me, this looks like a bug. What do you think?

[Jack-Devel] OS X Binaries

by g4-lisz＠tonarchiv.ch

Hey guys! Sorry, this is probably the wrong place to ask this, but I could not find any contact e-mail address on the Jackaudio website: Where can I download the latest binaries for OS X? The links on the download page are not working, i.e. the files have been removed. Cheers, Till

[Jack-Devel] Jack 2 download for Windows not available

by Pablo Emilio Andrade Velasco

Hello! I am a fan of Jack and would like to install it in my Windows computer for routing audio from Serato DJ to a compressor vst and back again to Serato. However, the download for installing Jack 2 on Windows is not available on the download page. File not found Sorry, that file doesn’t live here anymore. It might have been moved or made private. This message is displayed from dropbox. Is there any chance I could have access to the download any other way? Thanks a bunch! Pablo Andrade

[Jack-Devel] Windows executables are missing from jackaudio.org?

by Juliana Cherston

Hello, I am trying to port a project from Mac to Windows, but when I try to download the executables from jackaudio.org I am given a 'file not found' error from Dropbox. Is there any place that the 32 bit .exe. file is still accessible, and is it possible for it to live in a more stable place for future users? Thanks! Juliana

[Jack-Devel] Jack 2 binaries download links (dropbox) no longer valid.

by Peter Ginneberge

I just was told that the Jack 2 download links listed on the website no longer work. http://jackaudio.org/downloads/ I believe this has something to do with DropBox having changed a thing or two recently. regards, Peter

[Jack-Devel] jack_get_client_pid inconsistent api?

by yarl

Hello, I am writing a program that needs jack_get_client_pid (I don't want to use dbus). I first tried to link with libjack, but that function is "not implemented on library side". So, after interpreting some mails in this list I tried linking with libjackserver, which worked. Just to remind: int jack_get_client_pid (const char *name); I do not completely understood what is libjackserver compared to libjack but what I do is that libjackserver defines a larger API and I noticed differences in number/ownage of threads and initialisation of the server. The best way to keep a client's code clean and simple seems to be to link with libjack. If I understood well, libjackserver is supposed to define functions in 'jack/control.h'. What about jack_get_client_pid, then? jack_get_client_pid is declared in 'jack.h'. Moreover, it is declared in 'jack.h' for jack2 (line 225): https://github.com/jackaudio/jack2/blob/master/common/jack/jack.h but it is not in jack1's API: https://github.com/jackaudio/headers/blob/07f1ecf1ce119d861ec631cb4a6a81a1a… I thought about implementing that function in jack2 on library side. I guess that this function is similar to, for instance, jack_get_uuid_for_client_name, even if the process identifier is sort of outside jack. Anyway, jack_get_client_pid seems a bit inconsistent with the rest of the API. Why is it not declared (and renamed): int jack_client_get_pid(jack_client_t* client, const char* name); ? Moreover, declared like that, the implementation on library side is straightforward (because we have 'client'). But it's too late for the API to change. I actually implemented jack_client_get_pid (thus augmenting the API) and can request for a 'to review with care' pull if you are interested. bye
