Re: [Linphone-developers] Audio distortion when using ARM device Bug i think

[menno]

There are some problems with the hardware i think. I use a simple 48Khz
soundcard. (The period size 256 is not supported by your hardware.).

Can i resolve this problem? Because i get distortion in oneway audio (only
mic to other device, not from other device to headphone).

This is the linphone short debug log:
ortp-message-synchronizing timestamp, diff=480
ortp-message-alsa_open_r: opening default:0 at 8000Hz, bits=16, stereo=0
ortp-warning-alsa_set_params: The period size 256 is not supported by your
hardware.
 ==> Using 170 instead.
ortp-warning-alsa_set_params: periodsize:256 Using 170
