I m using the same example code on my app

This is a bug on the audio lib? or my app?
i have put a lot of try and catch on this app, i dont put only on this code

    If FirstTime Then
        streamer.Initialize("streamer", mSampleRate, mMono, mBitRate, streamer.VOLUME_MUSIC)
        buffers.Initialize
        timer1.Initialize("timer1", 1000)
        mps.Initialize2("mps")
    End If

The error can is on this code.
how can i fix this error, and this is from lib or my app?

The app with this error its this

thx again.

Based on the error the parameters you are passing are not supported. What are the values of these variables?

You can catch this error and initialize the object again with 11025 instead of 22050.

oK Thx erel i will do it.

 

[sorex]

I had these errors aswell depending on which device it was running. 8KHz seemed to work on all of them so enter 8000 is you still have problems.

 

[Douglas Farias]

The reports continue i dont understand why
here whate i made to try fix

    If FirstTime Then
       
        Try
        streamer.Initialize("streamer", mSampleRate, mMono, mBitRate, streamer.VOLUME_MUSIC)
        Catch
        streamer.Initialize("streamer", 11025, mMono, mBitRate, streamer.VOLUME_MUSIC)   
        Log("Erro Stream 11025")
        End Try
       
       
        buffers.Initialize
        timer1.Initialize("timer1", 1000)
        mps.Initialize2("mps")
       
       
       
    End If

This means that the device doesn't support the parameters provided.
