Re: question about sampling rate

Hi Clemens,
 
I am not yet handling the fractional part of frame size, would it be cause of the distorted sound? I was expecting to hear music with some noise though, but nothing good is coming this time.
 
The endpoint says, adaptive synchrnonization, but no address is defined in the syncaddress field of the endpoint descriptor.
 
Do i have to consider the synchronization before I could  hear some music in my streamed data?
Thanks for all the help.
 
regards,
 
grace

yes you're right.

How did you set the sample format?  Are there endpoint-specific
controls?
 
no endpoint specific control is set. sample format is based on the max sampling frequency from the format descriptor.

How do you handle the fractional part of the frame size?

Is this an adaptive endpoint, or what synchronization type does it have?
