Installing USB Microphone on FC6

Lee Duke · 12-13-2006, 09:28 PM

I've just installed FC6 and I'm trying to get my Logitec USB Microphone to work with the system. My Creative Labs (Audigy) sound card works fine with my speakers, but I didn't want to use the cheesy microphone that came with that. I know the Logitec microphone is good because it works fine on my Window$ machine.

Any help?

I'm trying to capture and process sound in real-time. I'm not currently trying to record.

Thanks.

My first suggestion would be to check the version of alsa (cat /proc/asound/version) you have. If it's older than 1.0.14rc1, get the new one here. There has been a lot of usb audio support added in the last couple of months.

I tried ALSA 1.0.14. Everything went well:
./configure
make
make install (as root)

Now, nothing works! Before (with 1.0.12) I could at least use my speakers through my sound card.

The entire sound system is floating face down in some stagnant pool. You got any other good ideas?

If I can't get the microphone to work, I'd be happy to just get back to having my speakers work.

Check your mixer settings. Also, check to see if the new sound drivers are loaded (lsmod | fgrep snd). Check dmesg to see if there is any error messages.

I have the same version running here on my Audigy, and it works well. Full surround sound.

This is what /sbin/lsmod | fgrep snd gets---

I don't know what any of it means.

Here's the part of dmesg that seems relevant:

usbcore: registered new driver snd-usb-audio

I hope that gives you some clue so I can fix this.
