I've used your demo to test bass, but whenever I try to add my stream something weirds happens and I get error (not the only type, I also get "Left channel deserializing error")

I've changed the following in the AudioManager.swift

            var channel = HSTREAM()
            channel = BASS_StreamCreateURL("https://stream10.xdevel.com/audio12s976748-1798/stream/icecast.audio", 0, 0, nil, nil);
            /*
            // Create a sample stream from our MP3 song file:
            stream = BASS_StreamCreateFile( BOOL32(truncating: false),  // mem: false = stream the file from a filename
                                            filePath,                   // file:
                                            0,                          // offset:
                                            0,                          // length: 0 = use all data up to end of file
                                            0)                          // flags:
             */
            BASS_ChannelPlay(channel, -1) // starts the output

Another problem is that this is the only stream that's giving trouble, why is this problem happening?

EDIT: forgot to mention that the stream correctly starts, but fails after a while

First of all, thanks Keith for this demo app and the clear instructions.

I've followed them to install Bass in my own project.

I just have two questions:

1. I want to be able to use Bass to play to whatever audio device is selected in my app by a user from a menu.
2. Can you explain how I can create a queue of urls for playback?

For the first question, it appears that Bass doesn't identify Audio devices in the same way as MacOS. For example the built in speakers have an AudioDeviceID on my Mac Air of 64. Let's imagine for a moment this is not the default audio device. So I replace -1 in the Bass init with 64 (Converting first to the expected Int32). Nothing plays, so this obviously not how Bass recognises the device when it is not the default.

There is a BASS_GetInfos function; but I can't figure out how to call it form Swift. If I could get an array of devices as recognised by Bass, I could check the correspondence with the AudioDeviceID I want to use from MacOS.

For the second question I'm sure this must be possible. I'm just wondering if you know if anything is already built into Bass to facilitate this?

Thanks in advance for any advice you can give.
