The call of function updates the status of runtime with the latest position of audio data transmission, checks overrun and underrun over buffer, awaken user processes from waiting for available audio data frames, sampling audio timestamp, and performs stop or drain the PCM substream according to configured threshold.

Developer should pay enough attention that some callbacks in :c:type:`snd_pcm_ops` are done by the call of function: - .pointer - to retrieve current position of audio data transmission by frame count or XRUN state. - .trigger - with SNDRV_PCM_TRIGGER_STOP at XRUN or DRAINING state. - .get_time_info - to retrieve audio time stamp if needed.

This will help the user space to load the device-specific Use Case Manager (UCM) configurations for the card.h]hX`An Intel machine driver may be used by many different devices but are difficult for userspace to differentiate, since machine drivers usually use their own name as the card short name and leave the card long name blank. To differentiate such devices and fix bugs due to lack of device-specific configurations, this function allows DMI info to be used as the sound card long name, in the format of “vendor-product-version-board” (Character ‘-’ is used to separate different DMI fields here). This will help the user space to load the device-specific Use Case Manager (UCM) configurations for the card.}(hjM~hhhNhNubah}(h]h
