Hi,

EDIT: not seen previous open issue related to it: #9

netaudio device list
gives me error on Windows 11:
site-packages\netaudio\console\application.py", line 1, in <module> from signal import signal, SIGPIPE, SIG_DFL ImportError: cannot import name 'SIGPIPE' from 'signal' (C:\Program Files\Python312\Lib\signal.py). Did you mean: 'SIGFPE'?

Seen there: https://stackoverflow.com/questions/58718659/cannot-import-name-sigpipe-from-signal-in-windows-10

Replacing this solved in https://github.com/chris-ritsen/network-audio-controller/blob/master/netaudio/console/application.py the problem for me:

try:
    from signal import signal, SIGPIPE, SIG_DFL
    signal(SIGPIPE, SIG_DFL)
except ImportError:  # If SIGPIPE is not available (win32),
    pass             # we don't have to do anything to ignore it.

But don't know if it's the best solution.

Attempting to add a subscription by channel number does not work (results in RuntimeError: coroutine raised StopIteration).

I think this is because it's attempting to match channel.number (which is an int) against self.option('rx-channel-number') (which is a str). I added a line of debugging to commands/subscription/_add.py as follows:

# ...
elif self.option("rx-channel-number"):

            for ch in rx_device.rx_channels.values():
                print('Considering', ch.number, type(ch.number), type(self.option('rx-channel-number')), ch.number == self.option('rx-channel-number'))
# ...

resulting in:

$ netaudio subscription add --tx-device-name StreamPC --tx-channel-name Right --rx-device-name VisualsPC --rx-channel-number 1
Considering 1 <class 'int'> <class 'str'> False
Considering 2 <class 'int'> <class 'str'> False
Considering 3 <class 'int'> <class 'str'> False
Considering 4 <class 'int'> <class 'str'> False
Considering 5 <class 'int'> <class 'str'> False
Considering 6 <class 'int'> <class 'str'> False
Considering 7 <class 'int'> <class 'str'> False
Considering 8 <class 'int'> <class 'str'> False
Considering 9 <class 'int'> <class 'str'> False
Considering 10 <class 'int'> <class 'str'> False
Considering 11 <class 'int'> <class 'str'> False
Considering 12 <class 'int'> <class 'str'> False
Considering 13 <class 'int'> <class 'str'> False
Considering 14 <class 'int'> <class 'str'> False
Considering 15 <class 'int'> <class 'str'> False
Considering 16 <class 'int'> <class 'str'> False

In case it makes a difference, this is on both Python 3.8 and 3.9, using v0.0.10 of netaudio.

DanteDevice.add_subscription passes tx_channel.name to its command_add_subscription method. Dante naming weirdness means that channel "names" are always '01', '02' etc.

This works, and audio is routed appropriately, but it confuses Dante Controller into not knowing where that subscription is coming from: it gives green checkmarks against the tx device, but doesn't know which column to put them in.

By way of example: here ATEM-Input is subscribed to channels 1 and 2 from SQ6-Broadcast. The subscriptions were made with netaudio.

These channels have friendly names of Broadcast L and Broadcast R respectively. You can see that Dante Controller thinks the subscriptions are actually to channels called 01 and 02 - which, surprisingly, works and audio gets passed appropriately.

Should add_subscription be using these friendly names if present? (Come to think of it, should these friendly names be used in place of names everywhere they're used?)

I propose to add a section with related projects in README.md.

I'm developing an open source reverse-engineered unofficial Dante implementation - Inferno. Currently it emulates Dante receiver and can be used for recording audio.

The earliest public attempt of reverse engineering Dante is wycliffe. I haven't tried running it, but looks like it implements requesting subscriptions from Dante devices. It probably won't be visible in Dante Controller.

dante-aes67-relay.js - this small Node.js program relays a Dante multicast stream to AES67

I couldn't find any other open source projects related to Dante, but many Dante devices are AES67-compatible, so this list of AES67 audio resources could be linked to as well.
