 Brian,

Probably the USBAudio driver is getting confused because of this:

FTDscr:
  db FTDscrEnd-FTDscr  ;; Descriptor length
  db CS_INTERFACE ;; Descriptor type
  db FEATURE_UNIT ;; Descriptor sub-type
  db 2  ;; Identificador del Feature Unit
  db 1  ;; ID de la Fuente de se=F1al
  db 1  ;; Control Size
  db 03H  ;; Controles Master ch: Mute y Volumen
  db 00H  ;; Controles ch 1: Ninguno
  db 0  ;; Nombre de la Feature
FTDscrEnd:

Where you have placed the volume control on the Master channel and not on
ch.1.

Thanks.
Devendra.
