Hi there, I run openSUSE Tumbleweed and Leap 15.2 (beta) on different machines. I just did a fresh install of both on two different laptops, with the Mate environment. On the Leap system with slightly older package versions I can use Pavucontrol to switch between HSP/HFP and A2DP profiles on both of my bluetooth headsets, and they work on HSP/HFP for both input and output. However, on the newer Tumbleweed system I can switch the profile to HSP/HFP in Pavucontrol but it doesn't work, Audacity just freezes and VLC/Firefox playback freezes until I switch it back to A2DP. Which is obviously preferable for listening, but the problem is I need to record some low quality audio via HSP/HFP.
So I'm wondering which package version is making the difference. The two systems are configured almost identically. I tried the Leap kernel (5.3.18) on the Tumbleweed system, but it made no difference. Here are a few key package differences, please let me know if you think of anything else:
Tumbleweed:
bluez 5.54
kernel-firmware-bluetooth 20200519
libbluetooth3 5.54
libgnome-bluetooth13 3.34.1
pulseaudio 13.0
alsa 1.2.3
alsa-firmware 1.2.1
Leap 15.2:
bluez 5.48
kernel-firmware-bluetooth (package doesn't exist)
libbluetooth3 5.48
libgnome-bluetooth13 3.34.0
pulseaudio 13.0
alsa 1.1.5
alsa-firmware 1.0.29
I also tested Ubuntu 20.04, but it was the total opposite. Both of my bluetooth devices only connected via HSP/HFP, and the only way I could switch to A2DP was manually via `bluetoothctl`. I believe Ubuntu 20.04 has kernel 5.4, not sure about the rest of the stack.
Hi
I've done a new simulation, this time a HighGainAmplifier.
This one didn't try to cover any existing gear, but was stacked together
by from what I've learned over the last years about tube amp simulation.
This one is completely generated by dkbuilder in plain faust source code.
I've put the faust code into the repository for completeness.
The complete plugin is published under the BSD0 license.
Here you could get it:
https://github.com/brummer10/FatFrog.lv2
And because the Frog needs food, here is the perfect match Overdrive
pedal to feed the Frog so that he'll rattle the walls like hell.
The LittleFly.
https://github.com/brummer10/LittleFly.lv2
As well published under the BSD0 license, as well with included faust
source code.

MCPDISP is a utility to add a display on to a Mackie Control based
control surface that does not have it's own display such as the bcf2000.
This is important if banking is being used (the project has more than 8
tracks) and also provides things like timecode or bar/beat readouts.
At present this is a jackd only utility though it should be possible to
bridge to ALSA using a2jmidid. Perhaps a later version will move to ALSA
MIDI instead.
The latest version can be found at:
https://github.com/ovenwerks/mcpdisp/releases/tag/0.1.1
The main update here is the addition of a build system (meson) rather
than hoping a makefile will just work. Licenced as GPL-2+.
These things should help with packaging.

Hello all,
A new release of zita-jacktools is available at
<http://kokkinizita.linuxaudio.org/linuxaudio/downloads>.
>From the README:
Changes since the first release:
* General code cleanup.
* Python docstrings for all classes.
* New class: JackLR4filt
* 4th order Linkwitz-Riley or Butterworth filters,
with delay and gain.
* Typical use is crossover filters, also useful
for some measurements.
* Bugfixes:
* JackAmbrot: fixed a nasty bug which produced incorrect
rotation matrices. This also affected JackAmbbin.
* Some small changes:
* JackSignal: 'nskip' and 'nloop' are now supported for
both set_input_data() and set_output_data(), and must
be keyword arguments.
* JackGainctl: the 'rate' parameter is no longer supported.
See the class docs for how exactly gain changes are done.
* Some new examples, among them a PyQt5 application using JackMatrix.
Ciao,

Hello all,
Several users have reported instability problems (AKA 'crashes')
with Aeolus 0.9.7 and 0.9.8.
This should be fixed in version 0.9.9, as usual available on
<http://kokkinizita.linuxaudio.org/linuxaudio/downloads>
Ciao,

Hello,
are there some more examples how to use jacktools?
I'm mostly interested ind JackPlayer and JackGainctl.
thank you in advance,
all the best,

Anyone here using or had experience with XanMod kernels? -
https://xanmod.org/
I'm currently using Debian Buster with recent Liquorix which works quite
well but am now dipping my feet into keyboard-playing waters and wonder
if it's worth trying.
It does show some advantages in a recent Phoronix test compared to
Liquorix -

Hello everyone,
I'm trying to install and use zita-jacktools, but unfortunately I don't
get it to work.
https://media.ccc.de/v/lac2018-46-jacktools_realtime_audio_processors_as_py…
I managed to compile it and install it.
According to
http://linux-audio.4202.n7.nabble.com/zita-jacktools-available-now-td106280…,
I needed also to compile zita-convolver 4.0.0 first, which I did, and
which also went well.
I've done the following:
1. download and unpack:
- zita-audiotools
- zita-jacktools
- zita-jclient
- zita-convolver 4.0
2. make and install zita-jclient and zita-convolver:
- go to source, them make, then sudo make install
3. install zita-audiotools and zita-jacktools:
- go to folder, then python3 setup.py build
- then install with sudo python3 setup.py install
Now I can import jacktools in Python without errors. But if I try to use
it OR to run an example file (e.g. tobspect.py like in the ccc video), I
get the following error:
ImportError: libzita-jclient.so.0: cannot open shared object file: No
such file or directory
In the nabble thread, a user said that zita-jclient is installed to
/usr/local/lib64, but zita-jacktools only included /usr/lib as the
library path.
So I copied libzita-convolver and libzita-jclient from /usr/local/lib64
to /usr/lib, but I still get the same error message.
Does someone have any hint? I'm developing a open source Python
application, where I really need fast and rock solid interpolation for
the mixer faders, so I'd really love to use JackGainctl for this....
Here the full error message:
File "/media/sda7/Programming/Python/jacktooltest/main.py", line 3, in
<module>
   from jacktools import jackkmeter
 File
"/usr/local/lib/python3.6/dist-packages/jacktools/jackkmeter.py", line

   from jacktools.jackclient import JackClient

21, in <module>
   from jacktools import jackclient_ext
ImportError: libzita-jclient.so.0: cannot open shared object file: No
such file or directory
Thank you for any help!
All the best,
Vince
