I'd like to report a working device:

 Name: Prolink PixelView PlayTV
 Kernel: 2.6.23
 ID: 0x878-0x00:0x00
 Digital Rate: 128000 (I think)

I can record mono fine with arecord:

 % arecord -D hw:2,1 -f S16_LE -t wav test.wav
 Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono
 Warning: rate is not accurate (requested = 8000Hz, got = 119466Hz)
        please, try the plug plugin
 Aborted by signal Interrupt...

When I try to load the module with another sample rate (sudo modprobe
snd- bt87x load_all=1 digital_rate=44100) it still reports "...using
default rate 32000".

Also, I cannot record via the OSS-Layer: zapping hangs when I select
the /dev/dsp device, and
 streamer -C /dev/dsp2 -p 4 -t 0:03 -r 24 -q -o test.avi -j 90 -f
mjpeg -F mono16
only gives an error, but no sound:
 oss: read: Input/output error

Can you give me some hints on how to record video+audio and
determining the correct sample rate?

As I am not subscribed to alsa-devel, I would appreciate a CC of any answers.

Thanks in advance
