hi

The sound works fine in audacious, amarok etc... but not in tv
capturing applications.
I have a leadtek tv2000 expert tv card. The sound is connected to the
cd input on the motherboard.
The sound card is Realtek ALC888.

tvtime says:
mixer: Can't open device /dev/mixer, mixer volume and mute
unavailable.
sound device is set to /dev/mixer:cd

and xawtv:
open(/dev/dsp): No such file or directory

ls /dev/snd/
controlC0 hwC0D0 pcmC0D0c pcmC0D0p pcmC0D1p pcmC0D2c timer

lsmod | grep snd
snd_hda_intel 289052 2
snd_pcm 72068 1 snd_hda_intel
snd_timer 22532 1 snd_pcm
snd_page_alloc 11528 2 snd_hda_intel,snd_pcm
snd_hwdep 10756 1 snd_hda_intel

/dev/dsp and /dev/mixer are the old OSS interfaces.

/dev/snd is the new ALSA interfaces.

It seems as if you are missing the oss compability modules. I have no
experience from Slackware 12.1, but in Slackware 12.0 those modules are
loaded by default from /etc/rc.d/rc.alsa with the following lines:

echo "Loading OSS compatibility modules for ALSA."
modprobe snd-pcm-oss
modprobe snd-mixer-oss
modprobe snd-seq-oss

You may need to login as root once in order for the system to be able
to create the /dev/dsp etc.
