Sarge and bttv-alsa-artsd problem

I just installed debian sarge. My system has onboard via8233 sound card
and one pci tv card (Pixelview Playtv). With the default kernel 2.4.27
(i386,686,k7 versions) everything works fine and i have sound
everywhere. With apt-get install, i installed alsa-base and kernel
2.6.8-k7

When i boot with kernel 2.6.8 and kde starts this message appears

Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (No such device)
The sound server will continue, using the null output device.

Playing a little with xmms, i forced it to use the hw(1,0) card so i can
hear sound in xmms, but no sound at all at kde.

If i write alsamixer -c 0 comes the mixewr for the bttv card, and if i
write alsamixer -c 1 the mixer for the via 8233.

Here is my lsmod

If i write artsd

ALSA lib pcm_hw.c:1155

snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed:
No such device
Error while initializing the sound driver:
device: default can't be opened for playback (No such device)

If i remove the tv card from the pc, amd boot without it then sound
returns and kde starts without problem.

It is probably confilct with tv card and sound card with default sound,
but i can't figure it out. Any ideas?

Hello,
That is simply caused by the fact that the driver for the sound-device
on the TV-card is loaded first, but you can tell alsa to make the TV
card the secondary device.

echo 'options snd-bt87x index=1' > /etc/modprobe.d/tvis2ndary
update-modules

Right.

This is becoming a FAQ. We will add this information to the ALSA
documentation somewhere.

> update-modules

Note that update-modules is not necessary with 2.6 kernels.

I will give it a shot, but i am pretty sure that i don't have anywhere
the snd-bt87x option.

What does /proc/asound/cards say? Did you reload the modules in question after
adding the above option? The complete set of steps is:

echo 'options snd-bt87x index=1' > /etc/modprobe.d/tvis2ndary
(Stop all programs with a sound-related /dev file open.)
rmmod snd_via82xx snd_bt87x
modprobe snd_bt87x
modprobe snd_via82xx

Regards,

Stephen

Thanks. That workded. Basically i mistyped the snd-bt87x with snd-bt878x, so that's why it didn't workded.

Thanks a lot Stephen
