problem with generic hardware

Hello All,
i already posted about this problem using the "Generic Hardware", i apoligize since i should prepare more accurate data to analize, but i couldn't since i was redirected to other tasks. Actually, i am again back on it. I am streaming PCM 8Khz 16 bit data through the network, from a little embedded device to the OpenAL PC application. Packets contains 512 bytes each (256 samples). So every packet is sent every 32 msec, as 32 msecs of sound. The receiving code is mainly taken from the playstream sample and it's working well with the "Generic Software" configuration. I am queuing 4 packets as preload before playing. Switching to Generic Hardware, holes in the audio come immediately audible. So i collected some ticks timestamps, as you could see, at the pc side, using "Generic Software", every packet is played at an average of about 32msec (i have a Sleep(20) in the loop to release some cpu), as expected. In "Generic Hardware", there are delays >= 100msecs between every packet. I have also installed today the last runtimes library through your new installer, unfortunately, without any change. buffer processed 1: 0 is the first buffer played after the 4 buffers preload (": 0" mean 0 buffers processed). buffer processed 2: is the buffer played in the loop (": 1" mean 1 buffers processed only).

The borad is a "Realtek High Definition Audio". Any help is really appreciated.

Hi Angelo, If your application is working well via the "GH" device on other soundcards, then I would guess that the Realtek drivers are the problem. Do you have the latest drivers installed?
