AGL All Member Meeting Europe 2018

The current AGL audio solution currently relies on the default ALSA loopback card, which lacks per-stream security contexts, dynamically configurable PCMs, and places an upper bounds on the number of audio streams allowed. Mark and Karl present a solution - a secure “virtual” dynamic sound card, that would not only solve the aforementioned issues, but would also provide a unifying, standardized kernel-space audio integration pathway for existing low-level sound drivers. Mark and Karl will discuss the overall system design of the virtual sound card, outline the key challenges and benefits associated with it’s architecture, and provide some insight into its intended usage.
