The controls do work though, and they are being created - the code
fragment is below (with lots of printks for debugging)

static int __devinit add_aicamixer_controls()
{
	int err;
	err = snd_ctl_add
	     (dreamcastcard->card,
	      snd_ctl_new1(&snd_aica_pcmvolume_control,
			   dreamcastcard));
	     if (err < 0){
		snd_printk("pcmvolume failed\n");
		return err;
	     }
	    
	    err= snd_ctl_add
	     (dreamcastcard->card,
	      snd_ctl_new1(&snd_aica_pcmswitch_control,
			   dreamcastcard));
	     if (err < 0){
		snd_printk("pcmswitch failed\n");
		return err;
	     }

	    
	    err = snd_ctl_add
	     (dreamcastcard->card,
	      snd_ctl_new1(&snd_aica_mastervolume_control,
			   dreamcastcard));
	     if (err < 0){
		snd_printk("mastervolume failed\n");
		return err;
	     }

	    
	    err = snd_ctl_add
	     (dreamcastcard->card,
	      snd_ctl_new1(&snd_aica_masterswitch_control,
			   dreamcastcard));
	     if (err < 0){
		snd_printk("masterswitch failed\n");
		return err;
	     }

	    
	  
	/* succeeded */
	return 0;
}
