Hi all,<br>I hope someone can help me out with this, I've built a rootfs for a cirrus EP93xx. It uses i2s audio.<br><br>I've selected from make menuconfig<br>audi video libs....<br>|______> alsa<br> |__> directory with ALSA /dev/snd<br>
build PCMplugins ALL<br> build control plugins ALL<br> aload<br> mixer<br> pcm<br> rawmidi<br> etc<br>
<br>basically all the ALSA options<br><br>I've went to test my sound by searching /dev for devices sound etc. They don't exist?<br>I've tried to look in /proc for asound directory, it doesn't exist either<br>
However libasound.so.2.0.0 does exist in usr/lib ?<br>Although there is no aplay there is a file playsound_sample in /usr/bin I try to run and get numerous errors<br><br>/usr/bin #
/usr/bin # ./playsound_simple
<br>ALSA lib confmisc.c:768:(parse_card) cannot find card '0'

<br>/usr/bin # <br><br><br><br><br><br>I know my board kernel has sound as the provided rootfs will play it using aplay or my ALSA code, but very poorly it locks up the board when playing and I can find no way round it, that's the main reason I need a new rootfs, to try to get sound working to a normal level, there's no dmix set up either.<br>
<br>Can anyone advise how I can get sound, I'm not sure why it's not in /dev or /proc/asound? Thanks in advance<br clear="all"><br>-- <br>Regards Tony<br>
