The Audio codec encodes and decodes audio.
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.
