Thanks! This is a great notice. After the alsa problems ("kernel: saa7133[0] 
dsp access error") I've searched one card with this external connection!

Ok, I can return the card --one important detail when Linux users buy 
hardware: «I can return it when "doesn't works in Linux" is the reason?» :)

There my ALSA installation:

------------------
$ dpkg -l "*alsa*" | grep ^i
ii  alsa-base             1.0.11-2       ALSA driver configuration files
ii  alsa-firmware-loaders 1.0.11-1       ALSA software loaders for specific 
hardware
ii  alsa-tools            1.0.11-1       Console based ALSA utilities for 
specific ha
ii  alsa-tools-gui        1.0.11-1       GUI based ALSA utilities for specific 
hardwa
ii  alsa-utils            1.0.11-4       ALSA utilities
ii  alsamixergui          0.9.0rc2-1-9   graphical soundcard mixer for ALSA 
soundcard
ii  libsdl1.2debian-alsa  1.2.10-3       Simple DirectMedia Layer (with X11 
and ALSA
------------------

Now I use one custom kernel (vanilla, from kernel.org) 

------------------
$ uname -r
2.6.16.18-smp-bitassa
------------------

I was compiled this vanilla kernel --with no results-- just for the ALSA 
problem with the Debian kernel (2.6.16-12 smp).  Maybe is one ALSA problem?  
You've seen some workaround about this?

Good notice :)

Is sufficient. I only would create Ogg Vorbis files at high compression 
because are voice only --my weekly collaboration (one free software and 
Internet advocacy space in http://www.cadenaser.com > Mallorca Island station 
without Internet streaming)

I use the KRadio scheduling and Ogg Vorbis save functions.

Thanks for the review, Hermann!

(I've sent this message to video4linux-list too, I apologize because seems 
that have people in the two lists.  I'm new to this area, what is the 
appropriate list to ask, speak and contribute experiences about those cards?)

Cheers,
