Snd-bt87x

Note: The correct title of this article is snd-bt87x. It appears incorrectly here due to technical restrictions.

What Is It?

snd-bt87x is a Linux kernel driver for the Advanced Linux Sound Architecture (ALSA). It allows you to capture digitized sound directly from a bttv capture card, without hooking it to your sound card.

For a more generic overview of TV audio-over-PCI, including other (non-bttv) analog cards, see PCI TV audio.

Installing the Module

To use the snd-bt87x driver, the driver module needs to be installed. To see if your Linux distribution has already installed it, try

# find /lib/modules/`uname -r` -name 'snd[-_]bt87x*'

If it returns a filename, the module is installed. If it doesn't, you will have to get it installed. To do that, you will probably have to do one of the following:

• install it from a package included with your Linux distribution
• build it from the kernel source code included with your Linux distribution
• build it from the ALSA source code (available at http://www.alsa-project.org)

Loading the Module

Once the module is installed, it needs to be loaded. To see if your Linux distribution has already loaded it, try

<code># lsmod | grep 'snd[-_]bt87x'

If it returns one or more lines, the module is already loaded. If not, you will need to load it yourself. To do that, try

<code># modprobe snd-bt87x

If it doesn't give you any errors, use the lsmod command above to see if it's loaded.
