Thank you Greg It happens with AAC and mp3, I have played AMR files and they are played fine, But when I add the log dlls (log.dll and logobservefile.dll) in order to have a debug, they play slower and not continously. I will look to the code you mentioned. Best Regards Edgar

See if the audio device every runs out of data. Put print statements in CheckToPlayMoreAudio and see how often it is getting called. Does this happen with all content or just AAC? Check the output of GetCurrentAudioTime as well. --greg. > > > > -----Original Message----- > From: Greg Wright [mailto:[EMAIL PROTECTED] > Sent: Wednesday, September 14, 2005 12:52 PM > To: Edgar Luevano > Cc: audio-dev > Subject: Re: [Audio-dev] aac on emulator > > > Edgar Luevano wrote: > >>Thank you Greg. >>The file hxaudev.cpp and hxaudev.h seems that are not used >>for the build I'm doing (symbian 80 emulator), > > > Ah yes, we implement the audio stuff in symbian without inheriateing > from hxaudev.cpp. Try changing audsymbian.h: > > > #define MINIMUM_AUDIO_PUSHDOWN 1000 > //#define ENFORCE_MINIMUM_PUSHDOWN > > Just uncomment the ENFORCE_MINIMUM_PUSHDOWN and see if that helps.
