[Audio] PCM PLayback volume mancante

[stevr1it]

nel far partire con wine winmx mi è saltato fuori questo errore:
root@stevr1it-desktop:~# wine c:\\Programmi\\winmx4linux\\fake_windows\\ProgramFiles\\WinMX\\WinMX.exe
err:alsa:ALSA_CheckSetVolume Could not find 'PCM Playback Volume' element

fixme:shdocvw:OleInPlaceObject_InPlaceDeactivate (0x155e18)
fixme:shdocvw:OleObject_Close (0x155e18)->(1)

come lo risolvo?
ho ubuntu 7.04 e la scheda audio 24 bit creative
