Re: [alsa-devel] What is wrong in this code.

The code works just as expected when using the: snd_ctl_elem_id_set_name(id, "PCM Playback Volume"); But when I use the snd_ctl_elem_id_set_numid(id, numid); (with numid=23) it fails. ... snd_ctl_elem_id_set_interface(id, SND_CTL_ELEM_IFACE_MIXER);

//snd_ctl_elem_id_set_numid(id, numid); snd_ctl_elem_id_set_name(id, "PCM Playback Volume");

When using the numid to access elements, it must be the only field that is set in the elem id.
