[linux-dvb] no audio?

[Arpi <arpi@thot.banki.hu>]

Hi,

I've just got a "Galaxis" card, layout is the same as Siemens DVB-Sat.
Tried drivers:
  siemens_dvb-0.9-20010822.tar.gz  from linuxtv.org
  siemens_dvb-0.9-20010817.tgz  from VDR site
both stuff works, but i got no audio at all.
I think it's driver problem, because
- double-checked audio cables, etc. all is ok.
- got a captured (wiht VDR) file from friend and it has no audio here,
  but same file played with same progrem works for him

i've kernel version 2.4.3, with kernel's i2c-core compiled in.
(maybe a kernel upgrade helps? which version?)

dmesg output now, after running 'make insmod' and play this file:

i2c-core.o: driver VES1893 DVB demodulator registered.

dvb: 1 dvb(s) found!
dvb: playback 480x576 fr=3

i've programming (even driver programming) skills, but i know nothing
about these chips, so i'm stuck :(
If you give me some start point where and how to debug things, and which
files contain audio control. (for example, tell me, where is audio handled,
and how is it connected to system? i2c or via other chip, maybe it's
built-in to something other)

i've found 2 interesting stuff relating to audio:
msp3400.c has lots of audio code, but it isn't compiled
  (and it doesn't compiles, but i loaded msp3400.o from kernel but not works)
dvb.c has the 'adac' parameter. i tried both adac=0 and adac=1, nothing.

oh. and i've read somewhere in sources/readmes, that some timing problems
still exists. i've realtive fast machine (cel2@1066MHz), maybe it is the prob?

thanks for help,
