USB microphone not found

[hendry]

On my X220 Archlinux, my GoMIC USB microphone works just fine. But I can't seemingly get it working on my rpi. What am I missing?

Built in sound capability on the Pi is just output, not input. Like the error message says, you need a sound card, one that will enable to Pi to take sound input.

It works under 2014-01-07-wheezy-raspbian.img. Just need to diff the modules somehow. At first glances the loaded audio modules look the same ...

Try adding a line to your modules.alias file with the appropriate Manufacturer and Product ID.

Or is it already listed there? It is not on mine, but I have not updated recently. I think your file location will be something like the following, but with a different kernel number.

/usr/lib/modules/3.6.11-18-ARCH+/modules.alias

[hendry]

AFAICT there is no kernel module loaded in Raspbian that isn't loaded by my ArchlinuxArm.

$this->bbcode_second_pass_code('', '
[hendry@alarmpi ~]$ arecord -l
arecord: device_list:268: no soundcards found...
')

I'm very confused. What am I missing?

[sdjf]

The fact that a module is listed in lsmod does not mean that it will necessarily recognize any particular device. If you have logs enabled, it will show if the device is attached to or recognized by a driver or module. That file is what tells the kernel what drivers are appropriate for what devices. If a device is not in there, either specifically or covered by wild cards, then it will not be associated with the module, at least that is my understanding from my experience with devices that were not attached to drivers until their correct IDs got added to that file.

I would check your logs in Raspbian to see which driver the microphone is attached to. I don't know if there is a simple command that will do that, see what devices are associated with which drivers.

[moonman]

Check "usb-devices" it lists the driver there. Though it may not be the full list.

[sdjf]

ah, usb-devices is a command, thanks moonman, I was looking for a file and googling did not turn up anything obvious.

And the Archlinux Arm which isn't working:

It's loading the same kernel drivers AFAICT, so I really don't understand why I get `arecord: device_list:268: no soundcards found...`
