Symbol.Audio Namespace

Hi Experts,

I’m developing an application using PPT8800, CE.NET 4.1 and Visual Basic.NET to be used as an access control device for scanning barcodes on tickets.  I would like to emit beeps from the devices speaker after the barcode has been looked up in a back office system.  If access is to be allowed, then sound a short higher pitched beep, if access is to be denied sound a longer lower pitched beep.  I’m using the PlayAudio method to make the speaker on the device make the sounds.  This partially works the beep does sound, but I’m not able to alter the duration and frequency of the beep as the PlayAudio method suggests I should.  

Do you have any suggestions on how to solve this problem?

Thanking you in advance,

peraps you can make 2 Midi's or wav's and play a different one for the Status of the transaction.

I was already playing out the \windows\default.wav and \windows\exclam.wav as a work around.  I'm still puzzled as to why the method isn't working as suggested in the Symbol Mobility Developer Kit.

Wave file cannot be changed the frequency and duration. For BEEP only, you should use the notify class rather than audio class in symbol library. In there, a function let use configure the beep sound frequency and duration.
