Hey,
I was wondering, seeing as the latest distributed compiled package (on http://jackaudio.org/downloads/) for osx is version 0.90, and it is stated as beeing for Snow Leopard ; was wondering if i should try to compile it myself from the 1.9.10 tarball (or even the git repos ?) ; because i'm not very knowledgeable in coding so i'm afraid i have no idea how to compile it. Opening the xcode project in the git repo, then trying to compile it ; leads very fast to a critical " 'aften/aften.h' file not found" error ; and i don't see a "aften" file in the distribution.
In short, i do'nt know how stable is the 1.9.10 or Github version, but i'm not sure it is very wise either to use the maybe outdated 0.9 ? but for now, i don't know how i could do else...
Thanks in advance,
Victor

You are looking for jack-devel@. CCed now.
And the answer is no, JACK does not control application level volume, it
just forwards and merges audio streams.
If you want volume control, use a mixer (maybe one of not too many
jack-based mixers), so you can adjust each jack client's volume in one
place.

Hi jack list !
I try to get transport sync via netjack2 for a live music, light and
video show, and :
With the "net" driver, i don't find any option for turn on the transport
sync, so the slave start with "Transport sync : no"
With the "netadapter" internal , the connection seem good, with
"Transport sync : yes" but I got lot of errors on the slave. The log is
here : http://www.phuck.ovh/wargreen/pub/logs/netjack_netadapter_1.log
How to get the transport sync woking ?
Thanks a lot,
Wargreen
Hello,
I've been playing around with Jack/Netjack and the Opus codec in order to
setup a "low latency" WiFi audio stream at home.
After compiling Opus with custom modes and Jack2 with Opus support (both
from the master branches of the respective repositories), I was able to run
the Master-Slave setup:
Master.
jackd -R -d alsa -d hw:1 -D=false -r44100 -S -n16
jack_load netmanager
Slave:
jackd -R -d net -C0 -P2 -o0 -i0 -O320 -M1200 -l5
+ jack_connect to route the net input on the master to the speakers
But as I was getting quite frequent audio deterioration, with the master
showing messages like these:
Packet(s) missing from... -1 1
Wrong packet type : a
JackEngine::XRun: client = SLAVE_HOSTNAME was not finished, state = Running
JackEngine::XRun: client netmanager finished after current callback
JackAudioDriver::ProcessGraphAsyncMaster: Process error
Wrong packet type : a
Packet(s) missing from... -1 1
JackAudioDriver::ProcessGraphAsyncMaster: Process error
JackEngine::XRun: client = SLAVE_HOSTNAME was not finished, state =
Triggered
I've thought that maybe I should just try increasing the network latency
argument on the slave, as, for my use case, I'm happy with latency < 200
ms.
By using something like -l30 (the maximum I'm allowed to set) on the slave
I was able to greatly diminish the Process errors (I still get the same
lots of wrong packet type and packet missing messages though) but it didn't
fix the audio artifacts. Actually sometimes this change makes the playback
even worse with ms pauses every second.
So I would like to know if there is any other way to relax the low latency
requirement in order to improve playback reliability. Or is there some kind
of incompatibility in the configuration I'm passing to both endpoints that
is causing these problems?
Thanks!
André.
Dear Leonardo,
Thank you for your reply. I've considered Jacktrip before, but is not an
option because it doesn't run on Windows (and I have one Windows laptop at
home). I didn't know nj-bridge at all. Where can I find more information
about it?
Thanks.
André.

Hi,
using jack 0.124.1 I happened to do this:
const char *connect_to="";
err=jack_connect(client,connect_to,myport);
and expected jack_connect to return an error. To my surprise it
succeeded and connected "system:capture_1" to myport.
Is this "normal" and/or documented?
AFAICT, the technical reason is
jack_port_shared_t::alias2="\0" (resp. alias1)
and jack_get_port_by_name() returns the first such one...
Tobias
workaround is something like (in transport.c)
+int proc(jack_nframes_t frames, void* arg) { return 0; }
int main(int argc, char *argv[])
{
+ jack_set_process_callback(client, proc, NULL); /* for jack1 */
