Hi Jerzy,
Have you checked with a more recent Desktop Video driver? The most recent release is 10.9.7.
Can you try and monitor the audio frame count using the IDeckLinkOutput::GetBufferedAudioSampleFrameCount method[1]. Can you check that the audio frame count is remaining at a reasonable level and that it does not grow over time (ie new samples are written faster than they are output). As a rule of thumb, you should keep the buffered audio sample frame count to less than 1 second.
For the HDMI issue - which pixel format are you targeting for output?
Kind Regards
Cameron
