Problems as below : 1) SNDRV_PCM_TRIGGER_STOP in snd_usb_substream_capture_trigger() is not getting called. 2) We have tried calling snd_pcm_drain(), snd_pcm_drop() and snd_pcm_close() from application, which should STOP the PCM device as from API description. But still SNDRV_PCM_TRIGGER_STOP is not getting called. Please can you suggest the possibilities of SNDRV_PCM_TRIGGER_STOP not called in usb alsa capture driver. Also please suggest how to achieve the above ? Thanks in advance !! Response wil be appreciated !!! Best Regards,
