[alsa-devel] Unable to play aplay

[vasudha rao]

Hi Anuj,

Nodes were not there before..I created now..

Now when I did $aplay -l ,
I got,

 **** List of PLAYBACK Hardware Devices ***
*ALSA lib control.c:739:(snd_ctl_open_noupdate) Invalid CTL hw:0
aplay: device_list:208: control open (0): No such file or directory
aplay: conf.c:3083: snd_config_update_free: Assertion `update->count > 0 &&
update->finfo' failed.Aborted

Where I am doing wrong..??













Thank you..
