Hi There,
We have imx283 processor based system with Linux-2.6.35.3 ported. And have an requirement to play media file in the 4.3 inch lcd panel connected to the system.
The system has two sound cards; card 0 – snd-dummy and card 1 – USB audio(default).When a media file is played, card 0(snd-dummy) is used for playing audio. But the requirement is to use card0 (snd-dummy) for playing audio only if USB speaker is NOT plugged in. so as to achieve that we tried to make snd-dummy as default by changing /root/.asoundrc file. Still we couldn’t make snd-dummy (card 0) as default. System used snd-dummy for playing the audio(no audio at speaker).
Please share us some suggestion to make snd-dummy as default.
root@freescale /root$ cat /root/.asoundrc
pcm.default {
type hw
card 0
}
ctl.default {
type hw
card 0
}
root@freescale /root$ aplay -l
