The Advanced Linux Sound Architecture (ALSA) - library
6a617cc719
Tested with the Wolfson WM8524 DAC on a i.MX6UL board and the following
ALSA configuration file using the pcm test utility from alsa-lib:
"""
$ cat /etc/asound.conf
pcm.!default {
type plug
slave.pcm "softvol"
}
pcm.softvol {
type softvol
slave {
pcm "hw:0"
}
control {
name "Master"
card 0
}
}
ctl.!default {
type hw
card 0
}
ctl.softvol {
type hw
card 0
}
$ pcm -D softvol -o S24_LE -c 2 -r 48000
"""
The data in the Synchronous Audio Interface (SAI) of the i.MX6UL is
aligned the following way:
"""
31 30 29 28 | 27 26 25 24 | 23 22 21 20 | .. | 3 2 1 0
## ## ## ## ## ## ## ## [ DATA[23:0] ]
"""
