I don't know what kind of gadget you have, but the basic problem is that the microphone shows up as a separate sound device. So what you'll have to do is to configure a virtual sound device whose capture channel is taken from the USB mic and playback is your normal sound card. Furthermore, since Skype can't use alsa directly, you'll have to use some kind of a wrapper.

Here's some instructions. Skype will work with the aoss wrapper mentioned on the page. http://alsa.opensrc.org/asym

this probably can be done with the skype_dsp_hijacker script (I use the script myself to get rid of the "skype locks sound device" issue).

I can't record any sound through any microphone! I tried microphone through the soundcard jack - didn't work. Tried Logitech quickcam webcam (USB mike) - didn't work either. I tried both the steps mentioned in the two posts above - none of them worked either!

I got thsi :

./skype_dsp_hijacker --mic2nd
ERROR: ld.so: object '/usr/local/lib/libskype_dsp_hijacker.so' from LD_PRELOAD cannot be preloaded: ignored.

How to make it...?

Thank you !

I'm using a Logitech USB headset with Skype wich worked out of the box on Breezy. When I connect the headset a window pops up that new hardware is found and leading directly to system->preferences->audio where I select the Logitech USB headset as the new default device. In Skype i have selected /dev/dsp1. That's it. In Hoary it should be not as easy because you could not select the default audio device afterwards AFAIK.

Friedrich Are u using gnome or kde for this ? Do you see ur logitech headset in the alsamixer ? Is it present the /dev/dsp1 in audacity ? I just tried to plug / un plug with my breezy and it's not saying anythg... I am stuck with that since 1-2 months now ...

Thank you

I'm using Ubuntu with Gnome. I can see the headset as "Logitech USB Headset" when I call the alsamixer with

alsamixer -c 1

otherwise I get the built in Intel sound chip of my Acer Travelmate. I do not use audacity but I can record sound using sweep which is a similar program for Gnome users.

alsamixer -c 1 gives : no mixer elems found ;.....

Thank you VERY much !!!

I first copied: > pcm.!default { type plug slave.pcm "combined" }

pcm.combined { type asym playback.pcm "playback" capture.pcm "hw:1,0" }

pcm.playback { type dmix ipc_key 1024 slave { pcm "hw:0,0" period_time 0 period_size 1024 buffer_size 4096 rate 44100 } bindings { 0 0 1 1 } }

ctl.dmixer { type hw card 0 } into ~/.asoundrc,

then :

sudo rm /dev/dsp;ln -s /dev/dsp0 /dev/dsp #also try /dev/dsp1,2,etc.

sudo chmod 666 /dev/dsp0 sudo chmod 666 /dev/dsp

I am working on it or trying: I got such error msg for audacity after the ./configure --with-portaudio=v19 --without-portmixer

It was old post.

Is it for skype purposes ? Did you try the last skype 1.3 beta ? http://share.skype.com/sites/de/2006/06/linux_beta_13_mit_alsaunterstu.html it supports the ALSA. alsa gives much better results.

For me, it's fully working with skpye my usb microphones (VOip and an usb one too):KS

Just set up skype to use the USB soundcard:

Sound Devices:

Sound in: EasyCall Speakerphone HW Sound out: EasyCall Speakerphone HW

works like a charm under Gutsy
