Friends
I am using jack-scope -n 2 and I can see the plots are a different colour, if I squint. But there is not much in it, and nothing to indicate which plot is which colour...
I can see no way, in the man page, of making the data more distinct.
Is there a way of influencing the choice of colours and the size of the pixels, and adding some sort of legend?

Hi,
I just tried to get TetraProc (https://kokkinizita.linuxaudio.org/linuxaudio/tetra-pict.html) to run on an up-to-date
Arch Linux system (pipewire w/ pw-jack).
There doesn't seem to be a package neither in the official repos nor in AUR, so I went on to compile it.
I compiled and installed the dependencies as stated in the README, then compiled TetraProc.
I didn't encounter any errors during compilation, but when I start tetraproc I can only see the window flash
up briefly, then it disappears. There's no error on the console, or anywhere, so I'm not really sure where
to start ...
Does anyone have a hint?
Best,
Niklas
Hi list,
upon starting up the paulstretch software again after not having used it
for a long time, I experience reproducible segfaults when loading a .wav
file and trying to start playback. A gdb backtrace does not report much
except the following:
[...]
Thread 2 "paulstretch" received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7ffff6ccc6c0 (LWP 1670151)]
0x000000003f800000 in ?? ()

#2 0x00007ffff75d2235 in _Unwind_Resume () from /lib/x86_64-linux-gnu/libgcc_s.so.1
[...]
This is with either jack or alsa. Can anyone reproduce this? I am on
Debian stable with the paulstretch 2.2-2-4.1 package, which sadly seems
no longer available to (re)install.
This webpage for paulstretch's sources
https://hypermammut.sourceforge.net/paulstretch/
seems down as well.
Trying to recompile from some sources that I have lying around since years
in a folder called "paulstretch_cpp-master" using the supplied script
compile_linux_fftw.sh I get this compiler error:
[...]
XMLwrapper.cpp:32:26: error: invalid use of incomplete type ‘mxml_node_t’ {aka ‘struct _mxml_node_s’}
32 | const char *name=node->value.element.name;
[...]
What is the best location to get the last version of this great software
either as source or binary (package)?
Thanks!
Peter
I've been having problems with connections between jack clients dropping
out.
I would like to have a program that monitors the state of connections.
I've worked out how to locate the end client ports, but I don't want to
have
poll the connections at frequent intervals. Is there any way I can get a
callback when either of the clients drops out?
I suppose I could set up links between by monitor and the two client ports
and activate those connections, but that seems like overkill. Is there
an easier way.
I'm actually using pipewire-jack but don't know enough about pipewire to
do it
directly.

The function jack_set_graph_order_callback does this. The callback is
called whenever the graph of connections is changed. Then you can use
other jack functions to find out if your client has dropped out. I
don't know if writing a c program is an option for you, but there are
probably higher-level languages that have support for jack.

(Sorry if someone else has already replied this solution (I'm
subscribing to the mailing list in digest mode), but I could not find
any web archive of the linux audio mailing list working! Is there any
left?)
Hi,
I've just bought an ESI-Audio Gigaport-Ex to provide 8 output channels.
When I connect up to my Laptop which is running Debain 12 with Pipewire,
it appears on qpwgraph, but only shows two channels (Front-L + Front-R).
How can I persuade it to show all 8?
Thanks,
Bill

Hi,
I am undertaking a new recording project of my spoken voice. I am
sorting through the many plugin options. I am writing to solicit signal
chain recommendations, please
I am happy with jackd and qtractor. Here are the plugins I have running
on my computer.
-DAW PLUGINS-
autotalent
calf-plugins
ir.lv2
jamin
lsp-plugins
pulseaudio-equalizer
pulseeffects
rev-plugins
swh-lv2
zita-at
zita-rev1
Please be so kind as to share your recommended signal chain for this
project.
Kindest Regards,
Stephen
Hi list,
excuse this question as being partially off-topic, as not sound is
involved, but since some time (possibly since the last big Debian
upgrade), mpv complains about the video backend only being available as
"software renderer" and not being able to use "vo=gpu".
I run this on a Lenovo X230 with an Intel card and the i915 kernel
driver. I have learned that for older intel hardware (than my card?)
users are recommended to use xserver-xorg-video-modesetting X11 driver
instead of the the xserver-xorg-video-intel one. And indeed, I can
switch back and forth between these two by (not) forcing the latter in
Xorg.conf as
Driver "intel"
With the modesetting driver, mpv plays flawlessly using the vo=gpu
output but Gem on PureData as well as glxgears stutter every few
seconds. Having researched the web further, I found discussions about
different performances of the two drivers.
However, I would simply like to have mpv play nicely with the intel
driver. Here is its output, that I can#t really make sense of despite
having searched the web for a long time. Perhaps anyone on this list is
able to help me further?
Thanks a lot! Peter

[vo/vdpau] VDPAU is most likely emulated via VA-API.
[vo/vdpau] This is inefficient. Use --vo=gpu instead.
[vo/vdpau] Warning: this compatibility VO is low quality and may have issues with OSD, scaling, screenshots and more.
[vo/vdpau] vo=gpu is the preferred choice in any case and includes VDPAU support via hwdec=vdpau or vdpau-copy.
