- ibl - Capture IBL size. (default = 0, minimum size)
-
- Module supports up to 8 cards. The module is compiled only when
- PCMCIA is supported on kernel.
-
- To activate the driver via the card manager, you'll need to set
- up /etc/pcmcia/vxp440.conf. See the sound/pcmcia/vx/vxp440.c.
-
- When the driver is compiled as a module and the hotplug firmware
- is supported, the firmware data is loaded via hotplug automatically.
- Install the necessary firmware files in alsa-firmware package.
- When no hotplug fw loader is available, you need to load the
- firmware via vxloader utility in alsa-tools package.
-
- About capture IBL, see the description of snd-vx222 module.
