deva-ctrl-intel_hda.so

Sound driver for the Intel High Definition Audio controllers

Note: You must be root to start this driver.

Syntax:

Direct invocation (also causes a new io-audio process to start):

io-audio -d intel_hda [opt[,opt...]] &

Mounting (requires that io-audio already be running):

mount -Tio-audio [-oopt[,opt...]] /lib/dll/deva-ctrl-intel_hda.so &

Runs on:

QNX Neutrino

Targets:

x86

Options:

pci xx
The PCI index of the card you want to attach to. If you don't specify this option, the driver attempts to find the first unused card in the system.

For card options that apply to all sound drivers, see the entry for io-audio.

Description:

The deva-ctrl-intel_hda.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-intel_hda.so is running, you can use applications with sound, and those that control the sound system.

Note: Graphics drivers run at a higher priority than applications, but they shouldn't run at a higher priority than the audio, or else breaks in the audio occur. You can use the on command to adjust the priorities of the audio and graphics drivers.

Examples:

Invoke deva-ctrl-intel_hda.so directly from io-audio:

io-audio -d intel_hda &

Mount deva-ctrl-intel_hda.so (io-audio must be running):

mount -Tio-audio /lib/dll/deva-ctrl-intel_hda.so &

Files:

deva-mixer-hda.so
Supports the mixer.

Errors:

When an error occurs, deva-ctrl-intel_hda.so sends a description of the error to the system logger (see slogger2).
