Decouple ARC and SAD
Couple ARC and SAD causes several issues.
1. Initiating ARC can lead to an extended delay in reporting the "ARC initiated" status, potentially causing failures in HDMI 1.4 certification testing. The specification mandates a response time between 200ms and 1s, but the process of binding with the SAD can exceed this limit.
2. Certain ARC devices might interpret the lack of a timely "ARC initiated" report as an error and consequently produce no audio output.
3. Repeatedly initiating ARC can trigger multiple "request SAD action" commands. This can result in duplicate SAD reports, potentially leading to some SADs being missed or ignored by the receiving device.
4. Devices like the Onkyo TX-NR696, which respond with a "feature abort" message before eventually sending the actual supported SAD, can create a situation where the TV fails to receive the subsequent, correct SAD information.
