Subject: SNDRV_PCM_TRIGGER_STOP not called
Date: Fri, 23 Nov 2012 17:14:50 +0530	[thread overview]
Message-ID: <50AF61B2.5@sasken.com> (raw)

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,
