Music Player Rework (1 Viewer)

@hwahrmann

1) I have pinpointed the code which is causing trouble with Rockstar

BassAudioEngine.Initialize() calling Bass.BASS_Init(0, 48000, 0, IntPtr.Zero, Guid.Empty)
BassAudioEngine.InitBass() calling Bass.BASS_Init(0, 48000, 0, IntPtr.Zero, Guid.Empty

If either of these lines are executed, Rockstar is only able to play one song until MP is restarted. I'm not sure why this is but it would be nice to get this properly fixed.

EDIT: More progress

After first playback starts, Bass.BASS_GetDevice() returns "1" which is correct device and everything works fine. But when playback is stopped, GetDevice returns "0" which is the "no sound device" initialized by above and the second playback won't work.

Then, if I use Bass.BASS_SetDevice(1) before playback, everything works fine. The problem with this is that this is an ugly hack and I don't actually know which device should be used (which device is actually the initialized one).

I'm not sure why switch to "0 no sound device" is done and where. Also I'm not sure why this no sound device should be initialized at all in MediaPortal?

2) Current BassAudioEngine code has few glitches
- Bug: if (Config.SoundDevice == "Default Sound Device") should be "Default DirectSound Device" at least in my system
- BassRegistration.BassRegistration.Register(); is called twice
- _initialized = true; is called twice (not sure if this is a bug)

I need the "No Sound" Device, because ASIO and WASAPI have their own init.
In RockStar you use the DirectSound Device. So if you have selected BASS Player and set the sounddevice in MP Config, then InitBass should select the right device.

Are you doing something in addition to what is shown ion your Stop Method? e.g. Freeing BASS?
Device Number #1 is always the default sound device set in the mixer

On my fork yes and on master it should too with the patch posted in this thread, but better to create mantis + own branch

In case you hadn't all noticed, @hwahrmann has linked a new build from the first post.

Please get this tested, particularly checking if any bugs you found are fixed. The sooner all confirmed bugs are fixed, the sooner we can get this merged to master, and when we do that, we will be 75% of the way to 1.4.0 (subject to testing)! MediaPortal 1.4.0 will not take as long as 1.3.0 did, and there will be some nice improvements in there!

The new version is working fine with 96KHz/24bit and the little stutters are finally gone. It works very stable untill now. I keep on watching.
Great job - Thank you!
