Hope anybody have a good ide.

I've installed the mythtv rpms and the mysql rpms. Initiatet the
database but have no sound when watching tv in mythtv. The picture is
OK. The TVcard is connected to the soundcard with a cabel.

The sound is working all other places including "TVtime Television

My system is Mandriva 2007.0

MythTv is version 0.20.20060828-3 and installed with RPMs from Mandriva:
[root at localhost ape]# rpm -qa | grep mythtv

Nothing is bloking the sound device: 
#fuser /dev/dsp nothing comes up

Form the log file:

[ape at localhost mythtv]$ tail -f mythbackend.log

2007-01-08 21:20:44.831 Please go into the TV Settings, Recording
Profiles and
2007-01-08 21:20:44.832 setup the four 'Software Encoders' profiles.
2007-01-08 21:20:44.856 Assuming RTjpeg for now.
2007-01-08 21:20:44.857 NVR: Error, unknown audio codec
2007-01-08 21:23:36.917 TVRec(1): Changing from WatchingLiveTV to None
2007-01-08 21:23:37.415 Finished recording Ukendt: channel 2061

Without any luck, I've traid to change the encoders profile from RTjpeg
to MPEG-4.
I've traid to change the softwafe encoders (v41 based) codec from from
MP3 to uncompressed.

When I look at the Mandriva hardware configuration I see:
Driver Module: ‎snd-emu10k1

When I look at the Gnome Audio Configuration sound capture I see: 

Audio confererencing sound playback is: ALSA - Advanced Linus Sound
Audio confererencing sound capture is: ALSA - Advanced Linus Sound

The Audio Output device in mythtv is ALSA:ice958:{ AES0 0x02 }.

I've used google, only to be more confused. Where should I look to
getting one step futher ?
(Please don't arsk my to install the myth source and compile/link :-) )

Is there any test I can do ? 

Here are some information:
[ape at localhost ~]$ more /home/ape/.mythtv/mysql.txt

# Set the following if you want to use something other than the
# machine's real hostname for identifying settings in the database.
# This is useful if your hostname changes often, as otherwise
# you'll need to reconfigure mythtv (or futz with the DB) every time.

# If you want your frontend to be able to wake your MySQL server
# using WakeOnLan, have a look at the following settings:
# Set the time the frontend waits (in seconds) between reconnect tries.
# This should be the rough time your MySQL server needs for startup
# This is the amount of retries to wake the MySQL server until the
# gives up
# This is the command executed to wake your MySQL server.
#WOLsqlCommand=echo 'WOLsqlServerCommand not set'

[ape at localhost ~]$ more /etc/modules 
# /etc/modules: kernel modules to load at boot time.
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line.  Comments begin with
