Sound problems on HTC pocket PCs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

If it really was about sound device (burstiness/unstability),
increasing audio device latency may solve the problem, e.g: add the
following lines into your config_site.h:
#define PJMEDIA_SND_DEFAULT_REC_LATENCY  140 or higher
#define PJMEDIA_SND_DEFAULT_PLAY_LATENCY 140 or higher
(you could also setting it runtime-ly via pjsua_media_config).

Regards,
nanang
