I'm trying to configure alsalib to make format conversion
the asound.conf is:
pcm.uda1345ts {
type hw
card 0
device 0
}
pcm_slave.sl1 {
pcm "hw:0,0"
format S16_BE
rate 48000
channels 2
}
pcm.mono_dup {
type route
slave {
pcm "hw:0,0"
channels 2
}
ttable.0.0 16
ttable.0.1 16
}
pcm.dualmono {
type plug
slave "sl1"
ttable.0.0 16
ttable.0.1 16
}
pcm.recmono {
type plug
slave "sl1"
ttable.0.0 16
ttable.1.0 16
}
pcm.recmono2in1 {
type plug
slave "sl1"
ttable.0.0 16
ttable.0.1 16
ttable.1.0 16
ttable.1.1 16
}
pcm.recmono1in1 {
type plug
slave "sl1"
ttable.0.1 16
ttable.1.1 16
}
pcm.swap {
type plug
slave "sl1"
ttable.1.0 1
ttable.0.1 1
}
pcm.normal {
type plug
slave "sl1"
}
pcm.!default {
type plug
slave "sl1"
}
ctl.!default {
type hw
card 0
}
the library version is 1.0.14a cross-compiled for avr32 with buildroot.
(Alsa utils 1.0.14)
a try to play a wav file with:
aplay -D normal fileaudio/wav/ilSegnaleDiTest.wav
and I get:
