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,

And why is that a problem?
