 Note that too many console logging messages will also disrupt the audio.

+ - '''Application crashes''' or '''device reboots''' when a call started (or accessing sound device) on S60 3rd ed FP1 devices. This symptom may be related to [http://wiki.forum.nokia.com/index.php/KIS000796_-_Frame_length_variation_for_G.711_encoder G.711 frame size variation issue] while our APS implementation is currently hardcoded to use 20ms G.711 frame size. We are working on this (enable auto-detection of G.711 frame size), meanwhile the temporary solution would be:
+   1. change audio frame time from 20ms to 10ms, i.e: {{{med_cfg.audio_frame_ptime = 10;}}}
+   1. in the {{{CPjAudioEngine::RecCb()}}} & {{{CPjAudioEngine::PlayCb()}}} of ''symbian_sound_aps.cpp'', change samples buffer size and its operations from 160 to 80.
+
+ - There is '''no audio''', but there seems to be no audio error/problem shown in the log/console. We encounter this when the version of {{{APSServer2.sisx}}} installed on the device is different to the version of APS SDK used for building the application.
+
+ - There is audio, but somehow it '''sounds unclear''' or there is '''breaking/random noise'''. It may be related to the first issue above, application with 10ms G.711 frame size is running on device with 20ms G.711 frame size.
