@Helios61
Thanx for the logs. Good testing! Scrolling further down in your first log would have told me MP does play it correctly

I think the problem is PureAudio not handling the 5.0 channellayout properly. It tries to initialize the WASAPI device to 5 channels which is probably not supported. Instead it should map to a 5.1 configuration.

Hopefully i can find some time coming weekend to fix it!

• Added WASAPI support.

Fine, a step forward

In a first test on my desktop (not htpc) WASAPI Exclusive is working, but not in Event mod (only Push). Of course this is normally working with my sound device. Maybe a problem with BASSWASAPIFormat?

Must do a deeper look...

About the source code:
- The current Post/PreBuild - scripts doesn't work for me, because I have spaces in my paths. You have to quote these.
- "High-End Music Player Plugin" is a good description. Should also be set in xmp2. And the current plugin requires MediaPortal 1.6.0, and not 1.2.0.

Just look at my diff to get an idea.

Update:
On my HTPC with a different sound device event mode is also not working.

@Wiedmann
Thanx for your input. Even though you seem to be the only one with spaces in your development paths , i can agree with your proposed changes, and will include them in the next release. May just remove the 1.2.0 dependency from the xmp2 though, doesn't seem functional.

Have you verified the wasapi event mode of your audiodevices actually do work with other software like foobar? Not all devices support it...

@Helios61

Could you test this for me? Should play 5.0 flacs correctly.

Been playing around with event mode...
On my onboard realtek device the combi exclusive/event doesn't work either. Shared/event does.
On my esi maya44 both combi's work.
Either the realtek doesn't support exclusive/event or there's a bug in the BASS lib. Not much i can do about it right now.

Hi @Symphy !

Thanks for your efforts, but unfortunately with the new version playback of this file doesn't start. Logs are attached.

Best regards,
Helios

@Helios61
Thanx for the test. Did you run that test with event mode enabled or disabled? Could you send that file to me?

@Symphy
Please check PMin 5 Minutes! Event mode is enabled!

Ok, for me that's: "%VisualStudioDir%\Projects\MediaPortal\pureaudio-mediaportal-plugin"
with "%VisualStudioDir%": "%USERPROFILE%\Documents\Visual Studio 2010"
(and "%USERPROFILE%" is also having a space)

With foobar it's working.

This code is also working:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Un4seen.Bass;
using Un4seen.BassWasapi;
using Un4seen.Bass.AddOn.Mix;

namespace BassTest
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                BassWasapiHandler _wasapi;

                Bass.BASS_Init(-1, 44100, BASSInit.BASS_DEVICE_DEFAULT, IntPtr.Zero);

                int stream = Bass.BASS_StreamCreateFile("test.mp3", 0, 0, BASSFlag.BASS_STREAM_DECODE | BASSFlag.BASS_SAMPLE_FLOAT);

                _wasapi = new BassWasapiHandler(Bass.BASS_GetDevice() - 1, true, true, 44100, 2, 0f, 0f);
                _wasapi.AddOutputSource(stream, BASSFlag.BASS_STREAM_DECODE | BASSFlag.BASS_SAMPLE_FLOAT);
                _wasapi.Init();
                _wasapi.Start();

                Console.WriteLine("Press any key to exit");
                Console.ReadKey(false);
            }
            catch (Exception)
            {
                Console.WriteLine(Bass.BASS_ErrorGetCode());
            }
        }
    }
}

Hi @Wiedmann ,

What version of bass.net exactly are you using? The constructor overloads in 2.4.10.0 (which comes with MP) do not match the documentation that comes with 2.4.10.3. See intellisense.

When using your code with 2.4.10.0, it doesn't use event mode as far as i can see. The following code will enable event mode:

_wasapi = new BassWasapiHandler(Bass.BASS_GetDevice() - 1, true, true, true, 44100, 2, 0f, 0f);

Apart from that, your errorhandling won't work.
Only the BassWasapiHandler constructor throws exceptions, which disappear into nowhere in your catch.
For all other methods and bass functions you need to look at the boolean return value and check BASS_ErrorGetCode when false.

bass.net is giving me these 3 constructor overloads:

public BassWasapiHandler(int device, bool exclusive, int freq, int chans, float buffer, float period);
public BassWasapiHandler(int device, bool exclusive, bool sessionVol, int freq, int chans, float buffer, float period);
public BassWasapiHandler(int device, bool exclusive, bool sessionVol, bool eventSystem, int freq, int chans, float buffer, float period);
