The Buffer Descriptor List has many entries, is it played serially?

Yes, it's the values that are sent to the audio DAC. It's typically an array of left and right channel data in PCM format.
If you have several sources/audio streams, you must use a mixer, or create your own mixer in software.

In other words, the left and right channel data in a stream appear alternately, so the audio can be played with a single stream, right?
