DMAI 1.16 + DM6446 + STEREO AUDIO

S.C
Intellectual 410 points

I try to use DMAI 1.16 on DM6446. I have this audio application,

*****************************************************

sAttrs = Sound_Attrs_MONO_DEFAULT;

hSound = Sound_create(&sAttrs);

Sound_read(hSound, hAudioInBuf);

Sound_write(hSound, hAudioInBuf);

*****************************************************

Then I can hear the sound OK (not good quality, MONO...), but if I change the sAttrs = Sound_Attrs_STEREO_DEFAULT, I would have no sound or very sharp noise only.

All the demos in the dvsdk for dm6446 show MONO only, what about STEREO? I just want the PCM mode, not any compression.

The dmai codes show that the driver will do 2 channels, but will do StereoToMono and MonoToStereo if hSound->channel is 1.

Any ideas? Pardon me if it has been discussed before. Thanks!
