Hi, I have installed linphone-1.0.1 on Bulverde PXA270 board alongwith libosip2-2.2.0 and speex-1.1.8.There are no problems cross-compiling the application but when I run the application linphonec(console version) and try talking with linphonec on a normal linux machine (with alsa-drivers) the audio quality is very poor.Ringing on both sides goes well but while talking I get cutted and heavy voice along with some delay.I do not have alsa-drivers installed on the board but have them on the linux machine. Is this the real problem of not having alsa-drivers on the board? or something else is creating the problem? How can I install alsa-drivers on the board? Is it really needed? Can anyone throw any light on this? Regards, Ojas
