[alsa-devel] SNDRV_PCM_TRIGGER_STOP not called

Hello All,

We are facing issue when forceful disconnection of isochronous USB ALSA device (IPOD).

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,
