>Description:
      i've got a card detected as:

pcm0: <Creative EMU10K1> port 0xd800-0xd81f irq 9 at device 9.0 on pci0
pcm0: <SigmaTel STAC9708/11 AC97 Codec>

sound output works, but mixer does not - i can query values with mixer(8) and set them as i like, but it does not actually change anything - volume is the same it was before.  'cat /dev/sndstat'
gives:

FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Creative EMU10K1> at io 0xd800 irq 9 kld snd_emu10k1 (4p/2r/4v channels duplex default)

'pciconf -vl' describes the card as:

pcm0 at pci0:9:0:  class=0x040100 card=0x80651102 chip=0x00021102 rev=0x0a hdr=0x00
    vendor   = 'Creative Labs'
    device   = 'EMU10000 Sound Blaster Live! (Also Live! 5.1) - OEM from DELL - CT4780'
    class    = multimedia
    subclass = audio
emujoy0 at pci0:9:1:       class=0x098000 card=0x00201102 chip=0x70021102 rev=0x0a hdr=0x00
    vendor   = 'Creative Labs'
    device   = 'EMU10000 Game Port'
    class    = input device

there are no errors nor warnings in the dmesg.
