Make a soundcard input available in an AES67 network

aes67-sender's Issues

No callback with JACK api

Hi,

I'm having some trouble with aes67-sender and JACK. When using ALSA everything seems to be working ok, but with JACK i get no audio callback in the code. I've inserted a log row in audio callback and there is nothing coming in. There is sound in jack 'cables', I've attached a VU meter using Carla and it seems fine. See log:

~/aes67-sender$ authbind --deep node aes67 -v -a jack -d 1 -c 2 -n "syshar"
Selected Jack as audio api
Selected 192.168.5.152 as network interface

Trying to sync to PTP master.

Any ideas?

Example how to combine PTP and AES67 stream

Hello

i installed the ptp4l package and started it:

sudo ptp4l -A -m -i eth0 -S -i lo

ptp4l[1247.384]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[1247.385]: port 2: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[1247.385]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[1254.157]: port 1: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES
ptp4l[1254.158]: selected local clock dca632.fffe.2481d2 as best master
ptp4l[1254.158]: port 1: assuming the grand master role
ptp4l[1254.556]: port 2: LISTENING to MASTER on ANNOUNCE_RECEIPT_TIMEOUT_EXPIRES
ptp4l[1254.557]: selected local clock dca632.fffe.2481d2 as best master
ptp4l[1254.557]: port 1: assuming the grand master role
ptp4l[1254.557]: port 2: assuming the grand master role

Then i launched the aes67 sender - i have a usb audio card connected

sudo node aes67 -v -d 2 -c 2 -n test --address 192.168.0.100

Trying to sync to PTP master.

Any suggestions or how to combine these 2 programs?

Error Could not sync to PTP master. Aborting.

I have PTP installed and bound to the eth0.

Why am I still getting this error ?

Run aes67-sender without PTP Master

It is currently not possible to run aes67-sender without PTP master. RFC7273 allows to implement a ts-refclk:ptp=traceable which could be implemented to use aes67-sender without a PTP master.

Compatibility with virtual sound cards or is it a PTP issue?

Hi!

I tried using this sender with VB-AUDIO virtual audio interface, and I get crackling and buffering issues in AES67 receiver. I haven't yet tried to eliminate this problem by trying a hardware sound interface.

Interesting thing is that when on verbose, there are PTP related messages flowing. Are these normal?

Not showing up in Dante controller

I was able to get this running on OSX. I have a dante primary and it seems to be able to see the AES67 stream (it's a dante DSP) but I'd prefer to configure the receive/transmit via dante controller and aes-sender is not showing up there under transmit. Any ideas?
