Cross referenced on an issue of the lib audify. your lib dosent work wirh ARM on an Raspberry pi. Can you specyfie it in your readme that its x64? Because node runs on ARM so it would be assumed that you would support arm aswell but thats not the case so a specification would be lovely. almoghamdani/audify#9

Add support for Ravenna streams with up to 64 Channels of audio. Audio backend should support that anyways.

Could you please help me?
I'm on ubuntu 20.04
Many thanks

Some streams don't play any audio. I've added a stream from the following SDP. This particular stream works fine as a source in this tool: aes67-linux-daemon. I'm not sure what else I can tell you for troubleshooting, is there a log file? There is no indication of any error within the app. As soon as I click Listen the machine begins receiving RTP packets but I don't hear anything. Other sources of a similar format (L24/48000/8) work fine. Here's a Wireshark screenshot showing the packets being received. One unusual feature of this particular stream is that the source device sends multiple streams, each on a different UDP port, all using the same multicast destination address. Is that a problem here?

Redundant streams are not recognized correctly, as there are two mediatype definitions in the SDP. A SDP for a redundant stream might be similar to the following (adopted from [1]):

v=0
o=- 1311738121 1311738121 IN IP4 192.168.1.1
s=Stage left I/O
t=0 0
m=audio 5004 RTP/AVP 96
c=IN IP4 239.0.1.1/32
i=Channels 1-8
a=rtpmap:96 L24/48000/8
a=recvonly
a=ptime:0.125
a=ts-refclk:ptp=IEEE1588-2008:39-A7-94-FF-FE-07-CB-D0:0
a=mediaclk:direct=963214424
m=audio 5004 RTP/AVP 96
c=IN IP4 239.0.2.1/32
i=Channels 1-8
a=rtpmap:96 L24/48000/8
a=recvonly
a=ptime:0.125
a=ts-refclk:ptp=IEEE1588-2008:39-A7-94-FF-FE-07-CB-D0:0
a=mediaclk:direct=963214424

Implementing stream redundancy correctly is quite a big task and would need a lot of testing. As a workaround I will ignore the second mediatype definition to support redundant streams.

Hi Philipp,
Do you plan to integrate visualization in monitor app?

Hello,
If I paste a SDP in with 2022-7 redundant streams, the application says its invalid.
