WinTV HVR-900 (usb 2040:6500) (model 65008) / no audio but clicking noise

Hi!

Since I really need analog TV support, I would like to bring this up again... :-)

Now i hacked the em28xx module,
so that it would try to get the audio data via the em28xx_alsa module...

But that fails in the usb_submit_urb() call in the em28xx_init_audio_isoc() function, because:
wMaxPacketSize of endpoint 0x83 is 0...

Does someone still know how em28xx_alsa was to be used properly? Is there some specialist, that could help me?
Markus R. doesnt like to do open src things anymore, or did I misunderstand that?

Btw: I have an em2882/em2883 chip, which needs to be handled by the em28xx_alsa module according to this page:
http://www.linuxtv.org/wiki/index.php/Em28xx_devices#em2880.2F2881.2F2883

Here is the em28xx related syslog from my box:
