Audio ADC uses a dedicated clock – the issue is that HDMI uses a single TMDS clock which is derived from video clock, and audio is synced to that. In case of SNES that clock ends up being jittery as SNES doesn’t provide a periodic hsync, so it can cause all kinds of audio/video stability issues on receivers. You might want to keep an eye on the de-jitter mod which is currently in testing.
