HS70 PRO headset is connected to PC using USB transmitter. I am able to pair headset with transmitter (LED on transmitter lights up) and I've also tested headset in windows, thus I'm sure headset and transmitter are fine. My kernel is compiled with CONFIG_SND_USB_AUDIO.
As far as I can see Linux detects transmitter. New sound card appears in alsamixer named "CORSAIR HS70 Pro Wireless Gamin" however in playback section there's only PCM field without volume and in capture section there's single field named Headset. I couldn't find any errors in logs.[/url]

UPDATE:
I've booted up Ubuntu Live and headset is working fine. Same picture in alsamixer though, thus I assume it's either normal behavior or it is just due Ubuntu using pulseaudio. I hope it is former and I just lack some key component, because in case of my Gentoo I would really (really) like to avoid pulseaudio if it is possible.

I found the problem - I forgot to switch to new sound card (the "Gamin" one). In my case it was card 2.
Code:
user@localhost ~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA ATI HDMI], device 3: Generic Digital [Generic Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Generic [HD-Audio Generic], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: Gamin [CORSAIR HS70 Pro Wireless Gamin], device 0: USB Audio [USB Audio]
  Subdevices: 0/1
  Subdevice #0: subdevice #0


Crude way to force usage of other card is adding
Code:
pcm.!default {
    type hw
    card 2
}

ctl.!default {
    type hw           
    card 2
}

to /etc/asound.conf for global configuration or to ~/.asoundrc for single user configuration.
