im responing to:

"If you have an unknown card, please mail the ID and board name to <alsa-devel[AT]alsa-project[DOT]org>, regardless of whether audio capture works or not, so that future versions of this driver know about your card."

i have an ATI TV WONDER VE (PCI) card.
im using slackware 12.1 with default kernel "root at cpu99:~# uname -a
Linux cpu99 #2 SMP Wed Apr 30 13:41:38 CDT 2008 i686 AMD Athlon(tm) XP 2600+ AuthenticAMD GNU/Linux"

im following this project here: http://www.domenech.org/bt878a-adc/alsa-e.htm
if you wouldnt mind telling me which version of alsa and with what config settings to get that to work i would much appreciate it.

"dmesg | grep alsa" reports the following

root at cpu99:~# dmesg | grep alsa
ALSA /root/building_area/ALSA/alsa-driver-1.0.16/alsa-driver-1.0.16/pci/bt87x.c:876: unknown card 0x878-0x1002:0x03
ALSA /root/building_area/ALSA/alsa-driver-1.0.16/alsa-driver-1.0.16/pci/bt87x.c:879: please mail id, board name, and, if it works, the correct digital_rate option to <alsa-devel at alsa-project.org>

here is my /etc/modprobe.d/sound contents:

alias snd-card-0 snd-intel8x0
alias sound-slot-0 snd-intel8x0
alias snd-card-1 snd-bt87x
alias sound-slot-1 snd-bt87x
options snd-bt87x index=1 load_all=1

when i built the driver i used:

"./configure --with-cards=intel8x0,bt87x" as per the project guide

i updated these  alsa alsa-driver-1.0.16, alsa-lib-1.0.16, alsa-utils-1.0.16 and alsa-oss-1.0.15

here is some more info

basically i just want the oscilloscope project to work.
I followed the oscilloscope project guide pretty good. http://www.domenech.org/bt878a-adc/alsa-e.htm

patched "aplay.c"
configured the "alsa-driver" like it said.

alsamixer -c1, alsaconf, kmix, audacity and baudline dont pick up the "FM", "CAPTURE", "MIC" and "CAPTURE BOOST" i think.

anyhow i apprecaite your work and if you could help me on this i would apprecaite it.
