Im trying to get my Logitec USB headset working. I have all the correct stuff in my kernel, along with in my /etc/modules.d/alsa config file... ill post them here, and you can let me know whats wrong with it. The weird thing is that before i had tried to use my headset, i used my speakers. Now, with even this current setup, sound still comes out of my speakers! I have no idea.

Here is my /etc/modules.d/alsa:

According to this post, a Logitech USB headset worked in Knoppix... Maybe one could get the ALSA configuraration information from Knoppix?

The German forum posting:
At this forum post the user reports success.

As well the next appears to be promising here.

I'm walking through this setup issue with a friend of mine that recently installed gentoo with not much success (with alsa and the device functionality. gentoo is working well) so far. This would be good to get worked into alsa docs most likely ... I'm seeing alot of cries in the wind regarding it.

Make sure you DON'T have 'USB Audio support' selected under 'USB Support' in your kernel config,

otherwise this driver will grab the device before ALSA can!

You DO need 'USB Audio support' selected under 'Sound/ALSA'!!!

I have been struggling with this for a week.

What I discovered today was that, with the headset plugged in, I was able to hear different levels of background noise on the headset as I used the volume slider in the USB mixer (alsamixer -c1 on my machine). I think the problem here may just be that the system is set up so that no /dev/* works. You can set 'options snd-pcm-oss dsp_map=1' or any number that works. Or - maybe - just change "alias /dev/dsp snd-pcm-oss" to /dev/dsp1.

Also, since the sound card number changes depending on whether the headset is plugged in or not on boot, you can also set - options index=0 or snd_index=0 for the first card and index=1 or snd_index=1 in for the second card in /etc/modules.d/alsa at the appropriate place (e.g. alias -snd-card0 snd-ice1712
options snd-ice1712 snd_index=0.
This fixes the sound card number to 0 or 1. I believe you have to put this option in for both cards.
I am not quite clear on the syntax for this option (index? or snd_index?), so if you have an idea please respond.

At any rate, my head set is live and responds to the volume setting in the mixer.

Is this any help? If I find the definitive answer I will respond.

Hi,

Yes that latest suggestion seemed to work for me.

I was trying to get a USB headset working with Skype. My /etc/modules.d/alsa file was almost identical to the one shown. I found that adding the line "options snd-usb-audio index=0" got it working reliably for two different machines.

I also had some lines for my onboard soundcard in /etc/modules.d/alsa. This was set as snd-card-1. it seems that Skype (and, apparently, Audacity) just grabs the first soundcard it sees, so the USB one must be set to snd-card-0.

A problem I did have though is that the keyboard would lock up whenever the headset was unplugged. There is another thread discussing this problem (lookup "Unplugging USB Headset breaks keyboard"), but essentially, it happens with both USB and PS2 keyboards. In my case I solved it by not plugging the headset in until after the machine had booted up. It seems that, provided the machine doesn't see the headset during the boot process (presumably through coldplug), then you can plug and unplug it as often as you like. Looks like a bug in coldplug.

The /etc/modules.d/alsa I ended up with was as follows:

Re: Options snd-usb-audio index=0.
I have two sound drivers - the ice1712 for my M-Audio Audiophile 2496, and usb-audio for the logitec headset.
I have the M-Audio set as index=0 and the Logitec as index=1.
The only thing I use the headset for is skype, and to do that I simply set skype to use /dev/dsp1.
