Thank you Greg. The file hxaudev.cpp and hxaudev.h seems that are not used for the build I'm doing (symbian 80 emulator),
The sources that are compiled when I make a (make clean, make copy) in audio/device are : audsymbian.cpp, audio_svr.cpp, audio_svr_cntxt.cpp, audio_session-mmf.cpp and fakeaudiodevice.cpp so probably i need to make the change in fakedevice?

This code here: #ifdef HELIX_CONFIG_MIN_PCM_PUSHDOWN_BYTES #define MINIMUM_AUDIO_PUSHDOWN 100 #else #define MINIMUM_AUDIO_PUSHDOWN 1000 #endif instead of 100, make it 1000 lets say. If that fixes it, then you can try to make it smaller if you want. --greg. > Thank you. > Edgar > > > > -----Original Message----- > From: Greg Wright [mailto:[EMAIL PROTECTED] > Sent: Tuesday, September 13, 2005 12:39 PM > To: Edgar Luevano > Cc: audio-dev > Subject: Re: [Audio-dev] aac on emulator > > > Edgar Luevano wrote: > >>Dear all, >>I have found that aac files played on the symbian device sounds like >>buzzing. >>But when I play the same file in the device, it sounds fine. > > > You mean emulator? > > >>Do you know why this happen?
