Audio usb ALSA error: No suitable mixer element found

Question

Hello everybody.
I've installed arch last week. I've some problem with my usb audio. The audio usb device works but i can't use a mixer, so audio control is everytime set on max.
I can't use my normal intel audio 'cause is broken. This is my aplay -l output:
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC268 Analog [ALC268 Analog]

Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: AUDIO [USB AUDIO], device 0: USB Audio [USB Audio]
Subdevices: 0/1
Subdevice #0: subdevice #0
When i try to play audio files on audacious, arch give me following error: Audio usb ALSA error: No suitable mixer element found.
I've set the audio usb device as default with asoundconf. If i try to use hd intel audio, the mixer works good, but when i get back to usb audio, mixer is absent. There is a way to set a mixer for the usb audio device?

As for the usb sound card I would try setting those parameters:
autoclock=0/1
ignore_ctl_error=0/1

Probably related to module options.
If you simply want to control the volume it would be easy to implement a softvol plugin. But this headset should have a volume control. What is the output of:
