[ale] Is Sound in Linux Single-Threaded?

[Jim Kinney]

Depends on software. ESD (and now pulseaudio) support multiple simultaneous
inputs to a single output. So I can play 2 sound tracks at once (cool! Pink
Floyd and Bach at the same time). The frontend tool, ESD or pulse, combine
the data to make a single output stream.

On the output side, the process is single threaded. It would be very
difficult to share the hardware device with multiple threads.
