Sam, I had the same problem a while ago. Try using the following capture pin descriptor: // Audio Capture Pin: AUDIO_PIN_CAPTURE // { &AudioCapturePinDispatch, NULL, { NULL, 0, NULL, 0, SIZEOF_ARRAY( AudioCapturePinDataRanges ), AudioCapturePinDataRanges, KSPIN_DATAFLOW_OUT, KSPIN_COMMUNICATION_BOTH, &PINNAME_CAPTURE, &PINNAME_CAPTURE, 0 }, KSPIN_FLAG_PROCESS_IN_RUN_STATE_ONLY | KSPIN_FLAG_FIXED_FORMAT, 1, 0, &AudioDefaultAllocatorFraming, reinterpret_cast <PFNKSINTERSECTHANDLEREX> (CAudioPin::IntersectHandler) }, -----Original Message----- From: Sam Tertzakian [mailto:sam@xxxxxxxxxxx] Sent: Monday, October 03, 2005 4:04 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: AVStream and Wave Devices Hi, Thank you for your offer...Let me first try the checked build of Sysaudio and see what that tells me. I should have tried that before. If I cannot get it work, then I will decide which version of the inf to send you. -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Matt Gonzalez Sent: Monday, October 03, 2005 1:46 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: AVStream and Wave Devices Hi Sam- I see that you've posted your pin descriptors; why don't you go ahead and post the rest of your filter descriptor along with your INF file. I'll take a look.
