No sound with Hasseb Audio over Ethernet Pro

[olm52]

I have bought Hasseb Audio over Ethernet Pro for testing AES67/RAVENNA:
https://www.hasseb.fi/shop2/index.php?route=product/product&product_id=65

I have configured AES67 and Hasseb device as explained here.
However no sound at all.

Maybe I am missing something. I have connected the device with Ethernet cable (input) and cable to the optical Toslink port (output to DAC)

I see that /proc/asound/RAVENNA is receiving audio signal.
The command used is the one recommended here:
speaker-test -D plughw:RAVENNA -r 48000 -c 2 -t sine
I note that the output is declaring 16 bit but the Hasseb supports only 24 bit

Moreover I see some strange errors in dmesg. For example:
[ 1344.346165] mr_alsa_audio_pcm_prepare for playback stream [ 1344.346168] Leaving mr_alsa_audio_pcm_prepare.. [ 1344.346191] entering mr_alsa_audio_pcm_hw_free (substream name=subdevice #0 #0) ...

I have just tried and it works for me.
On the daemon side select TIC frame size @1fs (samples) to 48 - 1ms

[olm52]

Yes I have already set this, but no sound.

[bondagit]

hmm strange, everything seems ok.
regarding:

speaker-test -D plughw:RAVENNA -r 48000 -c 2 -t sine
I note that the output is declaring 16 bit but the Hasseb supports only 24 bit

This is no problem as encoding conversion is done by the RAVENNA driver.

Anyway I have tried to send a 24 bit / 48 kHz with the same result:

That avail:0 is not right I think...

[bondagit]

No, this is correct. You can try to sniff the session with Wireshark or use another device.

I have tested the original RAVENNA daemon and it was working fine.
Adapting the SDP file for the input stream to the one used by RAVENNA now I can use the AES67 daemon.

Original SDP file:

the only problem is that stopping play there is a repeated sound of the last note for a few seconds

[bondagit]

Hey thanks for finding this. Could you identify what exactly in the SDP file is causing the issue ?

the only problem is that stopping play there is a repeated sound of the last note for a few seconds

Yes, I also have this on the Hasseb device I have here but the problem is not related to the daemon.

[olm52]

I will investigate. Tomorrow I will go on holiday for a week. I will re-testing at the end of July.

I have also an archlinux package already made that I could upload to AUR.

Another problem is that play stops after few minutes.
In dmesg I have
PTP Master announce timeout, resetting

systemd service is giving this:
session_manager:: failed to retrieve PTP clock info

[bondagit]

PTP Master announce timeout, resetting

Ok, this is an easy fix in case: I have recently modified the driver to reset the PTP slave state in case we don't receive any new announcement from the master in 5 secs, see code at ravenna-alsa-lkm/driver/PTP.c:1093.
Commit:
bondagit/ravenna-alsa-lkm@cdd64d2

[olm52]

I have just tested with last ravenna driver and last daemon. The version is r346.767d38d
I checked in the source code that the above commit is present.

After around 8 min. sound stops and in dmesg:
PTP Master announce timeout, resetting ...

[bondagit]

can you change the announcement interval of your PTP master clock ?
It looks like after a certain period your master clock stops sending announcements.
