What kind of audio does the null sink accept?
By default the null sink accepts only PCM audio. Provides a playback sink for devices supported by the Advanced Linux Sound Architecture (ALSA). The sink name defaults to alsa_output. You should (almost) never need to load this module manually.
When to use device ID in sink and source names?
The “device_id” argument is used by default as a part of the card name (if “card_name” is not given), and also in the card’s sink and source names. If you’re not happy with that for some reason, this argument can be given to be a substitute for “device_id” in the card, sink and source names.
