Hi Daniel and Gordon, 

Sorry for posting on such an old thread. I have recently started using the 
PlayStation Eye for audio processing and I have run into the same issue of 
ALSA only allowing the device to capture at 16khz sampling rate when it 
should be capable of 48khz. Your last post indicates that even with a 
patch, the device only sampled at 16khz and just played the samples faster. 
I am just wondering if either of you came up with a solution to this 
problem? Was it ever possible to record at a 48khz?

Any help or information would be greatly appreciated. 

Thanks,

Jacobson.
