[Alsa-user] (snd_ctl_open_noupdate) Invalid CTL hw:0

Hi, Alsa n00b here starting to bring up alsa on an embedded platform: openWRT for the Broadcom mips processor used in wireless routers, I have a Netgear WGT634U. http://www.openwrt.org 2.6.17 kernel, alsa-lib-1.0.13, alsa-utils-1.0.13, CMedia USB sound dongle. My error is: [EMAIL PROTECTED]:~#
