The UAC audio "Bi Bi Bi...." is due to the sampling rate.
The sample rate of audio from the HDMI machine are 44.1khz / 48khz.
The audio sample rate in the PC ( windows / MAC ) must equal the audio sample rate of HDMI
For eample:
if audio sample rate of hdmi is 44.1Khz and UAC audio 44.1Khz in the PC, the audio will be normal
if audio sample rate of hdmi is 48Khz and UAC audio 48Khz in the PC, the audio will be normal
If audio sample rate of hdmi is 44.1Khz and UAC audio 48Khz in the PC, the audio will happen "Bi Bi" noise.
If audio sample rate of hdmi is 48Khz and UAC audio 44.1Khz in the PC, the audio will happen "Bi Bi" noise.
