Hi Matthew, Thank you very much. Your solution gave me big help. The loopback
capture works well to capture HDMI audio output data. I play a song and ran
slience.exe as your suggesion but there was still
AUDCLNT_BUFFERFLAGS_DATA_DISCONTINUITY happened sometimes just like following
cases in your blog: >loopback-capture
Press Enter to quit...
IAudioCaptureClient::GetBuffer set flags to 0x00000001 on pass 5381 after
1088829 frames
Thread HRESULT is 0x8000ffff Could you please show me some suggstion on it?
I have another question: How much delay will be added for loopback capture?
Thanks in advance.
Many thanks,
Audleyswood

The designed solution to get audio that is playing is to use WASAPI loopback
capture.

Hi Experts,
My question: How to capture HDMI audio output data? Whether is sAPO a choice
for it?
I need the speaker data to do AEC.
In my Windows 7 x64 PC, the audio output data was sent to HDMI speaker. The
HDMI audio driver is Intel Display Audio driver.
Whether is sAPO a choice to capture HDMI audio data? Here, I can not change
anying about HDMI audio driver because it is Intel driver not ours.
I am newie on sAPO. Could somebody show me suggestions?
If sAPO is not good choice to capture HDMI audio data, How can I do? Is there
anohter way to do it?
Thanks in advance.
Many thanks,
Audleyswood
