There is assertion when specify iface=PCM or iface=PCM,name='' when using amixer -c0 cget

according to the synthax

[[iface=<iface>,][name='name',][index=<index>,][device=<device>,][subdevice=<subdevice>]]|[numid=<numid>]

amixer -c0 cget iface=PCM amixer: control.c:258: snd_ctl_elem_info: Assertion `ctl && info && (info->id.name[0] || info->id.numid)' failed. Aborted

amixer -c0 cget iface=PCM,name='' amixer: control.c:258: snd_ctl_elem_info: Assertion `ctl && info && (info->id.name[0] || info->id.numid)' failed. Aborted

So, the empty string isn't checked before assert(). It's bad. It must be easy to fix. Care to create and send a patch?

thanks,
