In the "simplified diagram," TI shows a single AVDD/DVDD/HP_VDD supply: http://www.ti.com/lit/ds/symlink/tas5717.pdf#2 Page 20 also suggests the use of a single 3.3V supply for AVDD/DVDD/HP_VDD. But this combines a number of separate pins. On 5711 we have dedicated pins for: PVDD_A PVDD_B PVDD_C PVDD_D AVDD DVDD On 5717 we have dedicated pins for: PVDD_AB PVDD_CD AVDD DVDD HPVDD I didn't see anything in the datasheet suggesting it is OK to have different voltages or power states on the various supply pins (other than the special voltage on PVDD). I can add as many regulator entries as appropriate.
