The Audio of the HDMI port generate high pitch sound..
you can hear it when TAPE LOADS, or though disk driver SIO sound or when steaming video through SIDE2 CART.
This pitch noise is not heard on the speakers connected to Audio out port

The HDMI audio has some issues, I have another bug to find this.
Did it on core 7 btw? If so I guess its aliasing from the adc noise? I need a low pass filter on input to the HDMI component I think.
So you are saying it happens with v7? OK that rules out the adc then.
HDMI audio to me seems very broken... Even just the 'bubbling' boot sound comes out wrong in my opinion.
HDMI audio is sounding better now in general (signed/unsigned). This high pitched noise is still heard in some cases though, so it needs further investigation.
Added a low pass filter and this is gone, to be released in v23.
