Significantly optimized the sound latency performance

Significantly optimized the sound latency performance, essentially refining the ring buffer algorithm to the extreme, ensuring good performance even on older devices (such as the A9X processor). For newer devices, turning off and then turning the sound back on once may achieve even lower latency.

Thank for your contribution! I'll look into this later. By the way, have you find out why bit rate is super low when using the Parsec SDK? It seems that this issue can only be ameliorated by using an USB ethernet adapter.

I have not encountered this issue here; I chose the Parsec SDK. Tested within a local area network, at 4K resolution with H.265 encoding. The bitrate is perfectly normal, and the clarity and smoothness are both excellent (the device is an iPhone 12 Pro Max). In contrast, another SDK is very laggy and unusable.

Hi, since you haven't enabled issue in your repo, I just ask here. Were you able to render with Metal? It seems that there's a bug with Parsec SDK that it will pass nil to setRenderPipelineState that will cause Set Render Pipeline State Validation renderPipelineState must not be nil. error and crash the app. Did you find a solution?
