This functionality reflects the approach often employed in Qualcomm audio cards, providing enhanced flexibility in DAI naming conventions for improved system integration and userspace experience. It allows userspace program to easy determine PCM stream purpose, e.g.: ~ # cat /proc/asound/pcm 00-00: speaker (*) : : playback 1 00-01: mics (*) : : capture 1 00-02: loopback (*) : : capture 1 The previous naming approach using auto-generated fe or be strings continues to be utilized as a fallback.
