I thought I would post this since there was a big conversation here a while
back about AES67 and the slow death of AVB due to lack of support.
Well I was talking with a guy from Meyer Sound who told me that AVB has been
resurrected from the dead. Apparently Cisco and other large network hardware
vendors were willing to back it as long as it was made more generic to
accommodate industrial uses that are also time-sensitive.
So apparently it has been re-branded as “Time-Sensitive Networking” and has a
lot more momentum behind it.

So make of it what you will. :) I just found it to be interesting.

Hi all,
This is a call-for-testing of my new ALSA driver for Digidesign 002/003
family. If you have these devices, would you please test the driver with
your devices and report your experience about it.
Especially, I want you to test MIDI port for machine control, because
developers have no 'console' models, just tested with 'rack' models.
When installing and testing, please follow this instructions:
https://github.com/takaswie/snd-firewire-improve
Patchset was already posted to alsa-devel and confirmed to
playback/capture PCM samples/MIDI messages by ALSA applications.
[alsa-devel] [RFC v2][PATCH 00/11] digi00x: new driver for Digidesign
002/003 family
http://mailman.alsa-project.org/pipermail/alsa-devel/2015-March/089708.html
Several issues are still remained:
* The port for MIDI machine control message is not tested yet, because
002/003 console model are required.
* When allocates 2 or more channel numbers for the device, after 15 to
20 seconds from playbacking, any PCM samples causes noisy sound. Then,
all of LED on the front panel light. The streaming still continues
correctly.
* The actual effects of external clock source is not clear. When set
the clock source is somewhat external, even if stopping the clock
source, the device continues to sound PCM samples against my expectation.
* The meaning of asynchronous messages is unknown. This patchset adds a
functionality to receive it in userspace. You can test it with updated
libhinawa sample script.
https://github.com/takaswie/libhinawa
In my plan, this patchset will proposed for Linux 4.2. But these issues
need to be clear till the merge-window.

Version 2.6 of the Vamp plugin SDK is now available.
http://www.vamp-plugins.org/
Vamp is a plugin API for audio analysis and feature extraction plugins
written in C or C++. Its SDK features an easy-to-use set of C++ classes
for plugin and host developers, a reference host implementation, example
plugins, and documentation. It is supported across Linux, OS/X, and
Windows.
A documentation guide to writing plugins using the Vamp SDK can be found
at http://www.vamp-plugins.org/guide.pdf.
Version 2.6 is a bugfix and minor enhancement release. For more details,
see the changelog at
http://code.soundsoftware.ac.uk/projects/vamp-plugin-sdk/repository/entry/C…

Hello Reuben,
I have been talking to a Intel guy at the last AES convention and he told
me they are supporting AVB (maybe he's reading this list as well). Another
strong signal regarding AVB not dead. We were specifically talking about
audio networking and multimedia.

Hi All,
As root, starting JACK1 0.124.1 on an almost totally vanilla
3.19.2-1-ARCH kernel fails. Output of kernel with JACK1 issue is
pasted below[1]. The same system works fine with the 3.18.9-rt5-1-rt
kernel.
Running "groups" tells me there is no group other than "root", so JACK
seems to misinterpret that there is an audio group on the "broken"
kernel.
Any suggestions as to what's going on? Thanks, -Harry
PS: I'm aware of the reasons to not run JACK as the root user or login
as root for daily use.
[1] Output while running "broken" kernel:
[root@audio ~]# jackd -ddummy

JACK is running in realtime mode, but you are not allowed to use

Your system has an audio group, but you are not a member of it.
Please add yourself to the audio group by executing (as root):
usermod -a -G audio (null)
After applying these changes, please re-login in order for them to take effect.
You don't appear to have a sane system configuration. It is very likely that you
encounter xruns. Please apply all the above mentioned changes and
start jack again!
Greetings,
The error and repair attached below come from my attempts to build
gmidimonitor on Fedora 19. As you can see, gcc is not what's required to
complete the build, but waf's cprogram calls gcc, not g++. Alas, I can't
find much information about the cprogram directive, and I'm always out
of my depths when C++ is involved.
Before anyone decides it's an "old code" issue, be advised that I have
to perform the same operation on the latest git pulls of xjadeo.
I'd like to know if there's a global solution, or at least a
compile-time export I can use to resolve the problem.
Fedora 19 x86_64, GCC 4.8.3
TIA!
Best,
dp
