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

[AW]

Hi!

Now I bought a Hauppauge WinTV HVR-900 (USB, DVB-T/analog Hybrid).

video is ok...
But: Audio sounds almost as bad as before (with that Pinnacle stick):
http://www.wgboome.de./hvr900.wav

I used this mplayer command:
mplayer -tv 
driver=v4l2:input=0:width=768:height=576:device=/dev/video2:alsa=1:forceaudio=1:adevice=hw.1:audiorate=48000:immediatemode=0:amode=0:norm=pal:chanlist=europe-west:freq=280
 tv://

The difference to the Pinnacle thingy is:
The correct audio isnt even in the background...
I hear just that clicking noise...

What did I do wrong?

PS: With my PCI PVR-250 i have no problem...

Thx.

Bye
Arne

today i found that i have quite good DVB-T connectivity...
but sometimes there r too many errors...

so i m still interested in analog tv...

after some rebooting and
after i dropped a lot of firmware files from 
http://konstantin.filtschew.de/v4l-firmware/firmware_v3.tgz into /lib/firmware 
(in addition to xc3028-v27.fw)
i can hear the analog audio,
but from time to time there is still this strong clicking noise...
example: http://www.wgboome.de./20110226,hvr.mpg (i blurred the picture due to 
copyright considerations...)...

could it be that i use the wrong amux?
i found that theory here (but i dont know if i can just change the kernel 
module):

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:

hi!

i was able to find an antenna position/orientation that allows good quality for 
7 stations with SNR above 0x78... *wag tail*
up to 4 stations with just one stick at the same time... *w00t*

so it is not as urgent as before that the analog audio part works...

thx...
