About a year ago I posted my original request here for any suggestions=20 in getting a set of USB speakers from Altec Lansing, model# FX5051,=20 working with ALSA. They're a set of 5.1 speakers with a built in USB=20 sound card. Sound does appear to work, but the mixer is locked at 100%.=20 There is no analog manual mixer, and the digital control dial exhibits=20 the same problem as alsamixer, so I have to find a way to adjust the usb=20 device's mixer volume in order to make the speakers usable. The speakers work fine in Windows XP, without installing any drivers, so=20 it would seem that this device is operating based on some standard. In windows, adjusting the mixer via the digital control dial, or via the=20 windows mixer control both result in the LED display moving in sync to=20 indicate the new volume setting. In alsa, adjusting the digital control dial doesn't appear to have any=20 effect, other then waking the LED display from its low-light mode.=20 Attempting to adjust volume from alsamixer likewise wakes the display=20 =66rom low-light mode, but also fails to significantly change the mixer=20 setting. When I say significantly, I mean that the mixer flips between=20 about 98% and 100%, when using the Up/Down keys (or PgUp or PgDown). End=20 appears to drop the volume to 0%, but Home doesn't restore it. Pressing the device's 'Power' button also behaves strangely. I can turn=20 the device off, but it is turned back on shortly afterward. No usb=20 connect/disconnect events appear here, instead, the power button seems=20 to function more like a mute. amixer -c 2 contents yields: atrus@kedri:~$ amixer -c 2 contents numid=3D3,iface=3DMIXER,name=3D'Tone Control - Bass' ; type=3DINTEGER,access=3Drw------,values=3D1,min=3D0,max=3D10,step=3D0 : values=3D1 numid=3D4,iface=3DMIXER,name=3D'Tone Control - Treble' ; type=3DINTEGER,access=3Drw------,values=3D1,min=3D0,max=3D10,step=3D0 : values=3D3 numid=3D1,iface=3DMIXER,name=3D'PCM Playback Switch' ; type=3DBOOLEAN,access=3Drw------,values=3D1 : values=3Don numid=3D2,iface=3DMIXER,name=3D'PCM Playback Volume' ; type=3DINTEGER,access=3Drw---R--,values=3D2,min=3D0,max=3D49,step=3D0 : values=3D48,48 | dBscale-min=3D-49.00dB,step=3D1.00dB,mute=3D0 I'm attaching the contents of 'lsusb -v'.
