Channel List Not Displaying All Channels

[muzicman82]

Hi, I have a Yamaha Rio3224-D2 and when I list channels, the list stops at RX channel 16 and there are 24. As a result, I can't issue commands to the channels that netaudio doesn't see.

Suggestions?

OK, yeah I definitely haven't tested with that device. I'm going to guess it uses a Audinate Dante Brooklyn II. I have a Shure AD4D, which also uses one. I mention this because it's the only device where I had weird reported channel counts that I had to find workarounds for to get the actual count. What kind of settings do you have on the device (specifically, the sample rate)? But anyway, without packet captures of the device responding to commands to list the channels/subscriptions, I'm not going to know what's going on with it enough to fix it.

Hey! I can get you whatever packet captures you need. I posted on the Gearspace thread about my latest progress. I'm very interested in how you got the long commands out of Dante Controller reduced by several bytes.

It does use a Brooklyn II.

Maybe I could come up with a workaround. The channel request command is split up into pages, but you could go out of bounds with the page index on requests until it errors. I'm checking for device reported channel counts and sample rate to calculate how many pages there should be and only doing that. In my case, the device reports more channels than it actually has.

[muzicman82]

Interesting. What should I capture for you that might help? I may be able to get your AnyDesk acess to the system if you want to mess with it directly.

I responded on gearspace. All I would need would be the responses to these two:

Channel count query: 27ff000aad5d10000000
Get receiver info: 27ff0010732a20100000000100010000

That receiver info command has an argument which determines the page being requested. My get_rx_channels function has this loop:

for page in range(0, max(int(self.device.rx_count / 16), 1)):

Max per page in the response is always 16 channels. So if it's not trying to get the second page, then the channel count query is responding with something weird. Would be helpful to know the sample rate you're using, as it affects channel count and I haven't tested that much with anything other than 48K.

I've got access to Brooklyn 2 and 3 modules (and Ultimo/ultimox & DEP) ... One of the BKII modules has 64 channels. 😁 I should be able to test multiple samples rates as well.

I've not tried using this project before, so I'll need to get up to speed on how to use it.

[chris-ritsen]

The only real way I'm going to support every device with this project is to add some optional debug logging that gets reported somewhere I can see. Haven't even thought about how that's going to happen. There's no way I could ever personally test all of these expensive devices.

My theory with this is that it's custom firmware thing as:
i.e. Rio3224 have differing Ins vs Outs, the Brooklyn 2 comes in 8 16 32 and 64 flavours.
Rio3224 32tx 24rx
Rio1608 16tx 8rx
Ri8 8tx
Ro8 8rx
Samples: 44.1kHz, 48kHz, 88.2kHz, 96kHz
Bit Depth: 24bit or 32bit (32bit gets converted to 24bit internally)

There may be something else weird as on Rio3224 the last out/rx 8 channels are 4x AES/EBU which might be labelled differently, I used to own one, I can't remember.

Yamaha must be using a 32ch but modifying the receive side of the device to a non-standard number.
Most devices have a symmetric in and out count. i.e. Sound Consoles or DVS, the stage boxes are more likely to have differing I/O values.

I have access to AVIO units, ULXD4D, WING64 and X-Dante card and FBT Infinito Dante, if you would like me to perform any testing.
