it seem there is a bug in snd-aloop
those IFACE_PCM "PCM Slave Channels" controls return 48000
static int loopback_channels_get(struct snd_kcontrol *kcontrol,
struct snd_ctl_elem_value *ucontrol)
{
struct loopback *loopback = snd_kcontrol_chip(kcontrol);
- ucontrol->value.integer.value[0]
=loopback->setup[kcontrol->id.subdevice][kcontrol->id.device].rate;
+ ucontrol->value.integer.value[0]
=loopback->setup[kcontrol->id.subdevice][kcontrol->id.device].channels;
return 0;
}
BTW , AFAIK dmix/dsnoop only work with subdevice 0 and there are 8
subdevices by default
How can the application access Loopback.pcm.default ?
