Ravenna AES Daemon / Any experiences with squeezelite

[s25a]

HI all,

I have found this on Github: https://github.com/bondagit/aes67-linux-daemon
I really like the idea with the virtual Soundcard that can publish Audio Data to a AES67 device.

I installed the packages and the driver - everything worked .

Here step-by-Step:

1) Step Build and Install

sudo git clone https://github.com/bondagit/aes67-linux-daemon.git
sudo ./ubuntu-packages.sh
sudo ./build.sh

2) AES67 daemon basic setup
https://github.com/bondagit/aes67-li...d#daemon_setup

open the daemon configuration file daemon.conf

set network interface name to your Ethernet card: "interface_name": "eth0"
set default sample rate to 48Khz: "sample_rate": 48000
set TIC frame size @1FS (samples) to 48 samples: "tic_frame_size_at_1fs": 48

Then load the driver

sudo insmod 3rdparty/ravenna-alsa-lkm/driver/MergingRavennaALSA.ko

And start the daemon

aes67-daemon -c daemon.conf

Then do some configs in the web interface and DANTE-Controller:

open the Daemon WebUI http://[address:8080] and do the following:

go to Config tab and verify that the sample rate is set to 48KHz and the TIC frame size @1FS is set to 48 samples
go to Sources tab and add a new Source using the plus button
set Codec to L24
set Max samples per packet to 48 samples
press the Submit button

Now you can play a Test File or do a speaker test

a@audioserver:~$ aplay -D hw:RAVENNA -r 48000 -c 2 -f S24_3LE test48.wav
Wiedergabe: WAVE 'test48.wav' : Signed 24 bit Little Endian in 3bytes, Rate: 48000 Hz, stereo

sudo speaker-test -D hw:RAVENNA -r 48000 -c 2 -t sine

That works :-)

However I have an issue to get it to work with squeezelite:

I start squeezelite with the necessary parameter:

a@audioserver:~/programs$ sudo ./squeezelite -W -n AES -a ::24: -R -u vME:::28 -r 48000-48000 -d all=debug -o hw:CARD=RAVENNA

But no AUdio :-( and a error in my DSP reporting: "Compromised - Packet Missing"

Any help is appreciated.

Did you have any success working through the issues with this. ?

I integrated picoreplayer & Ropiee into my Dante setup using the Audinate USB dongles but would love to try a purely software solution.

There is a new Ravenna Alsa LKM driver for Linux.
https://bitbucket.org/MergingTechnol...km/src/master/

The previous Butler was detected correctly by LMS/Squeezelite but no playback available with the Merging NADAC.
That doesn't mean that other player as the Anubis or Hapi may work.
