[alsa-devel] Indirect Callback with ack is called with no data

I am facing this issue with flash.

With aplay and paplay, the audio drivers are working perfectly ok.

With flash player, the audio stops after sometime. The reason is that flash player is not sending data. All the data sent from Flash has been played out and reported accurately as well in _pointer function.

Can anyone help with any clues of flash player working with ALSA? 

This would really help.

Subject: [alsa-devel] Indirect Callback with ack is called with no data


I am using indirect callback mechanism inside ack. I see that ack does not call my indirect callback pointer. Going through the code, I suspect that the appl_ptr is not being incremented and there is no data for the indirect callback to be called. 


After few acks, I get the indirect callback called. 


With aplay, I am able to play the wav file. But with flash, there is not data being sent to the driver.


Please help me with any clues.


Thanks in advance.
