The Audio codec encodes and decodes audio.

Contents

Hardware

The audio codec is a low-power 4 channel codec From TI.

Software

User

The audio codec is driven by pulseaudio, through ALSA. The ALSA interface is usually not exposed in maemo 5 - adding:

pcm.real {
	type hw
	card 0
}

ctl.real {
	type hw           
	card 0
}

to /etc/asound.conf enables a hardware device. Stopping pulseaudio may be required to use this.


Kernel

The codec is driven by a driver built into the kernel.
