Thanks for your response Rajesh, I have added the changes on your patch on my local copy, and I got an improvement in playing the clip, instead of starting to play not smooth after 2 seconds, it plays fine for 31 seconds, and then starts to play slower, and it stops at 39 secs. This is again only with one file (AAC 44Khz).

Hi Edgar, We have noticed a behavior in 6630 which was not occuring in earlier devices. The behaviour is that the Samples Played Count from Devsound resets after pause And Play. Pause need not be User initiated pause, even re-bufferring issues a pause to audio session. So handling has been put in place to handle samples played count reset . On helix we have seen this behavoiur for 6630 and on symbian 9.0 devices. I have submitted a CR already on symbian Audio changes. One of the change on it is to handle this case when HELIX_CONFIG_SYMBIAN_PLATFORM_SECURITY is enabled. And your second problem of audio not being smooth could be because of incorrect samples played timing calculation. Change for this is also part of the CR that I sent on Friday. CR: Symbian Audio Sessionchanges (audio-dev & porting-symbian mailing list) Regards, Rajesh. >-----Original Message----- >From: ext Edgar Luevano [mailto:[EMAIL PROTECTED] >Sent: Wednesday, September 28, 2005 1:19 PM >To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; Rathinasamy Rajesh >(Nokia-TP-MSW/Dallas) >Cc: audio-dev >Subject: error in AAC file related to hardware? > >I sent some email before about a bug when playing a specific >3gp file with AAC audio, (with other AAC files it just plays >fine is only a file that has a problem when playing) I'm >runnign Heix in a 6680 phone. > >, I found that a special flag is set in audio_session-mmf.cpp >when the device is a 6630. > >I set this flag and test again, and after this change helix >does not stop playback.
