Dears,

Sorry to bother again.

I used the audio graph processing method to play the mic-in and add effect to the sound to the speaker.

When I use the AUGraph_1 : RIO_input->Converter->
AUiPodE->RIO_output, it works fine and I can hear the sound play back.

But when I use the AUGraph_2 : RIO_input->Converter->

AUReverb2->RIO_output, try to add some reverb, the thing goes wrong,and no sound at all.

here is the log printed by using CAShow:

AUGraph_1>>>

node 1: 'auou' 'rioc' 'appl', instance 0x816f920 O I

node 2: 'aufc' 'conv' 'appl', instance 0x81713e0 O I

node 3: 'aufx' 'ipeq' 'appl', instance 0x8171740 O I

Connections:

node 1 bus 1 => node 2 bus 0 [ 2 ch, 0 Hz, 'lpcm' (0x0000000C) 16-bit little-endian signed integer]

node 2 bus 0 => node 3 bus 0 [ 2 ch, 44100 Hz, 'lpcm' (0x00000C2C) 8.24-bit little-endian signed integer, deinterleaved]

node 3 bus 0 => node 1 bus 0 [ 2 ch, 44100 Hz, 'lpcm' (0x00000C2C) 8.24-bit little-endian signed integer, deinterleaved]

AUGraph_2>>>>

node 1: 'auou' 'rioc' 'appl', instance 0x8151420 O

node 2: 'aufc' 'conv' 'appl', instance 0x7539df0 O

node 3: 'aufx' 'rvb2' 'appl', instance 0x7539210 O

Connections:

node 1 bus 1 => node 2 bus 0 [ 2 ch, 0 Hz, 'lpcm' (0x0000000C) 16-bit little-endian signed integer]

node 2 bus 0 => node 3 bus 0 [ 2 ch, 44100 Hz, 'lpcm' (0x00000029) 32-bit little-endian float, deinterleaved]

node 3 bus 0 => node 1 bus 0 [ 2 ch, 0 Hz, 'lpcm' (0x0000000C) 16-bit little-endian signed integer]

Is there something wrong?

Please help me with this, any clue will be great appreciated.

Best

Vincent
