Hello,

I'm working with a playstation eye and I'm attempting to grab the raw audio in order to perform some processing using it's 4 channel microphone array.

It's listed by the vendor as being a 48khz device. Using Audacity on OSX I can record 4 channels at 44,100hz.

However, under linux (raspberry pi running debian) I can only record in 16khz using ALSA.

arecord -vv /dev/null -r 16000 -f S16_LE -c 4 -D iec958:CARD=CameraB409241,DEV=0 /dev/null < /dev/null

Any higher rate won't be accepted. I tried this using the ALSA C API and also under the PortAudio API. Both without luck.

Any ideas on how to patch the driver in order to allow for 44100hz recording? The device is clearly capable of it.

Regards,

Benjamin
