Hi,
I have a PC running Mandrake 10.0 Community with kernel 2.6.3-4mdk, with a TV/FM card e SB Live 5.1. Everything is running perfect, for apps like xine and xmms, but there no sound for TV and radio apps (xawtv e gnomeradio). I tried almost everything, like changing modules.conf and switching off ALSA drivers, but nothing results. Now I using EMU10K1 driver but still having the same problem.
For a good soul how wants to help me there is my system info:

I cut the dmesg info. Its huge, but I think the most relevant (for this problem) is here. If you want to help me, please be gentle, I never compiled a kernel
Thanks

is `line` unmuted in alsamixer?

Hi,
Im not using alsa drivers.
But using aumix or ermixer line is 50% unmute.

so do you actually have the line-in cable connected? there's really ntohign else involved. you can mess with the btaudio module for recieving the sound digitally, but it's much easier just to plug the cable in, which bypasses all mention of drivers and sound servers...

I have a cable connecting de tv card out and the SB line-in.
How can configure the module.conf, modprobe.conf and modprobe.preload ......
Here my conf.:

modprobe.conf
alias eth0 8139too
alias sound-slot-0 emu10k1
options bttv radio=1 card=24 tuner=23 gbuffers=4
install scsi_hostadapter /sbin/modprobe imm; /sbin/modprobe ppa; /bin/true
install snd-emu10k1 /sbin/modprobe --first-time --ignore-install snd-emu10k1 && { /sbin/modprobe snd-pcm-oss; /bin/true; }
install usb-interface /sbin/modprobe usb-uhci; /sbin/modprobe ehci-hcd; /bin/true
remove snd-emu10k1 { /sbin/modprobe -r snd-pcm-oss; } ; /sbin/modprobe -r --first-time --ignore-remove snd-emu10k1

modules.conf
probeall scsi_hostadapter imm ppa
probeall usb-interface usb-uhci ehci-hcd
above snd-emu10k1 snd-pcm-oss
alias eth0 8139too
alias sound-slot-0 emu10k1
options bttv radio=1 card=24 tuner=23 gbuffers=4

modprobe.preload
....
scsi_hostadapter
bttv
intel-agp

I think the problem is in this files. But ??

Thanks again

I don't know the answer to your problem, but here's some suggestions.

1. Try to check that sound card line-in is working using a different sound source, so you can isolate the problem to the sound system or the tv card.

2. Check the sound FAQ in the BTTV driver source code (should be in the Documentation dir of the kernel source, or get the package from http://bytesex.org).

3. Maybe turn off that on-board AC97 sound chip in the BIOS? It seems possible it could be getting confused with the SB Live.

4. Check the bttv options in use are correct for your card.
