Beside volume control, Is it feasible to bind other controls (e.g.
Interaural Time Difference, Interaural Level Difference and SAMPLE RATE 
CONVERTOR - Doppler Effect ) to the substream ?


How can the alsa application access those controls
(SNDRV_CTL_ELEM_IFACE_PCM) using the handle return by snd_pcm_open() ?
