Sound driver for the National Semiconductor Geode family of chips
|
You must be root to start this driver.
|
Direct invocation (also causes a new io-audio process to start):
io-audio -d geode [pci=xx] &
Mounting (requires that io-audio is already running):
mount -Tio-audio [-opci=xx] /lib/dll/deva-ctrl-geode.so &
Neutrino
x86
- pci xx
- The PCI index of the card you want to attach to. If this option is not
specified, the driver will attempt to find the first unused card in the system.
The deva-ctrl-geode.so shared object is a device driver
DLL used by the
io-audio manager.
It uses the API described in the
Audio Developer's Guide.
While deva-ctrl-geode.so is running, you can use applications with
sound, and those that control
the sound-system (e.g. mixer).
Invoke deva-ctrl-geode.so directly from io-audio:
io-audio -d geode &
Mount deva-ctrl-geode.so (io-audio must be running):
mount -Tio-audio /lib/dll/deva-ctrl-geode.so &
- deva-mixer-ac97.so
- Supports the mixer.
When an error occurs, deva-ctrl-geode.so sends a
description of the error to the system logger
(see slogger).
You need a current BIOS to run deva-ctrl-geode.so. The BIOS
VSA (Virtual System Architecture) technology must be sufficiently up-to-date
to enable the native audio programming techniques used by this driver. If the BIOS
is too old, deva-ctrl-geode.so will exit and
slogger
will contain the exit message.
