Audio crackling problem with ParaLLEl-RDP #972

Closed lucasmr closed 2 years ago

lucasmr commented 2 years ago

RetroArch 1.10.3 (Linux) GPU Intel(R) HD Graphics 620 (KBL GT2) Core Mupen64Plus-Next (2.4-Vulkan c10546e), with the options:

Drivers GPU: vulkan Audio Driver: pulseaudio

Core Options RDP Plugin: ParaLLEl-RDP CPU Core: Dynarec RSP Plugin: ParaLLEl

The CPU and GPU usage are never going above 70% according to intel-gpu-top and htop, using the performance governor and maximum gpu frequency. However, there's constant audio crackling and skipping. Changing the audio latency to 512ms doesn't fix the issue. Tested under X and KMS with the same results.

Maybe it's a sync issue? Using GLideN64 as the RDP Plugin immediately fixes the problem, even with 1ms audio latency. Game tested was "Quake II (USA)" with the expansion pak enabled.
