USB Headset not working with alsa

I have a razer megalodon usb headset which works fine in ubuntu and windows but for the life of me I cannot get it to work in arch.

[exec@turbine ~]$ uname -a
Linux turbine 2.6.34-ARCH #1 SMP PREEMPT Mon Jul 5 22:12:11 CEST 2010 x86_64 Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux

1532:000e is the megalodon headset

Here's a relevant part of dmesg:

cannot find the slot for index 0 (range 0-1), error: -16

# /etc/modprobe.d/sound.conf 
#
#usb headset
alias snd-card-0 snd-usb-audio
alias sound-slot-0 snd-usb-audio

Alsamixer does not show my megalodon usually but I have seen it under device list a couple of times but I have been unable to get it to play sound.

Any help fixing sound would be appreciated greatly.

Try running alsaconf, seems to help some people with a similar issue. http://www.nvnews.net/vbulletin/showthread.php?t=75433

Check alsamixer to make sure that the particular output is not muted.

Re: USB Headset not working with alsa

I finally got it to work with the simplest solution of disabling the onboard audio using my bios.
