Hi all, I'm compiling the pjproject to windows mobile. After severals problems with sound device (latency and a inconstant clock rate) I have had problem with speaker and earpiece. I don't know how to use the earpiece instead of the speaker. I tried to follow the: 1)http://blogs.msdn.com/medmedia/archive/2007/01/16/the-wavedev2-forcespeaker-api.aspx 2)http://www.teksoftco.com/articles/article%20006/speakerphone.htm Does anyone know how to resolve this problem? Best regards, Popov
