[solved replaced] USB microphone

[stealth]

I have a new (as in just bought today) Logitech USB microphone the actual information identified for the device is:
Asahi Kasei Microsystems Co., Ltd AK5370 I/F A/D Converter
According to lsusb

I found through Google the Audacity wiki had instructions but I was not able to find the last thing it said to find.

http://wiki.audacityteam.org/index.php?title=USB_mic_on_Linux

lsmod | grep snd
and look for the modules usbcore, snd_usb_audio, snd_usb_lib. If they are loaded, the USB sound should work

nothing USB showed up in my output

Does any one have experience getting one of these USB microphones to work?

I know my microphone plugin on the sound part of my mother board works because I have an old microphone pluged in there, it works but the sound quality is awful. I need a newer microphone that will produce good quality sound for recording tutorials using RecordMyDesktop. If I can't get it to work i will just find a new microphone that plugs in where the old is so I can record.

[scoundrel]

have you checked for it in Kmix and picked it as the mic to use ?

[stealth]

sorry, yes that was the very first thing I did and that lead me to the search and steps I did share. There appears to be nothing available via usb and no way to access the usb mic in kmix. I probably have to install a library but I don't know enough about doing what I am trying to do. I chose to stay away from all of this sound stuff until now. doing searches in synaptic doesn't reveal anything (probably because my search words are no good). Doing searches with Goggle doesn't turn anything up initially until I start finding small chunks that give me a little education. Then I can do better searches and sometimes find answers. This is not one of those times yet.

From a root terminal;

In Skype, that's the sound device I choose for the microphone. You should also see it in your Kmix settings.

[root@fatman ~]# lsmod |grep usb

If you don't see something like above, try;

[root@fatman ~]# modprobe snd_usb_audio

Then again try;

[root@fatman ~]# lsmod |grep usb

Also see if there's anything in /etc/modprobe.conf about the usb sound, with this;

[root@fatman ~]# cat /etc/modprobe.conf |grep snd
#blacklist snd-usb-audio    <-- I had to comment out this line
remove snd_hda_intel /sbin/modprobe --first-time -r --ignore-remove snd_hda_intel
install snd_hda_intel /sbin/modprobe --first-time --ignore-install snd_hda_intel
options snd_hda_intel model=6stack-dig
alias snd-0 snd-hda-intel

[root@fatman ~]# cat /etc/modprobe.conf |grep usb
install usb-interface /sbin/modprobe ohci_hcd; /sbin/modprobe ehci_hcd; /bin/true
#blacklist snd-usb-audio
install scsi_hostadapter /sbin/modprobe pata_atiixp; /sbin/modprobe ahci; /sbin/modprobe ata_piix; /sbin/modprobe usb_storage; /bin/true

I have the same mic. This is the command I use when I do screencasts:


Code: [Select]

recordmydesktop -windowid $(xwininfo |grep "Window id:"|sed -e "s/xwininfo\:\ Window id:\ // ;s/\ .*//") -fps 15 -device hw:1,0
-device hw:1,0

is for the mic.

[root@fatman ~]# cat /etc/modprobe.conf |grep usb

yours show blacklist commented out

cat /etc/modprobe.conf |grep usb
install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe uhci_hcd; /bin/true
blacklist snd-usb-audio

I changed modprobe.conf so that blacklist was commented out and I am going to reboot to see what happens.

The mic is showing up in kmix now, but still not working. In kmix capture mic is checked. Commenting and un-commenting the blacklist snd-usb-audio had the same results.

Did you modprobe snd_usb_audio to load the module?

[stealth]

I did if it gets done during a reboot.

[Old-Polack]

I did if it gets done during a reboot.

It's a command you enter, as root, in a terminal. To have it done at boot, add snd_usb_audio on it's own line in /etc/modprobe.preload.

[stealth]

Did this modprobe snd_usb_audio no joy and then added the snd_usb_audio line to /etc/modprobe.preload and then rebooted

Still nothing.

How about the rest of the modules I showed in the other reply? Are they currently loaded? At least the ones that pertain to the usb sound? The items in the right column show the other modules that are interacting with the ones listed in the left column. All the ones that interact need to be present at the same time.

yes here is the out put of:
$ lsmod |grep usb
snd_usb_audio          82816  1
snd_usb_lib            19328  1 snd_usb_audio
snd_rawmidi            23072  1 snd_usb_lib
snd_hwdep              10756  2 snd_usb_audio,snd_hda_intel
snd_pcm                71428  3 snd_usb_audio,snd_hda_intel,snd_pcm_oss
snd                    51620  19 snd_usb_audio,snd_rawmidi,snd_hda_intel,snd_hwdep,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_pcm,snd_timer,snd_mixer_oss
usbhid                 48448  0
usbcore               135152  7 snd_usb_audio,snd_usb_lib,uhci_hcd,ohci_hcd,ehci_hcd,usbhid
ff_memless              8840  1 usbhid

All of the ones on the left are in /etc/modprobe.preload a reboot results in still no mic working.

What does the blacklist mean in /etc/modprobe.conf:
blacklist audio
blacklist snd-usb-audio

[stealth]

$ cat /etc/modprobe.conf |grep snd
blacklist snd-usb-audio
alias sound-slot-1 snd_hda_intel
options snd-ac97-codec power_save=1
alias sound-slot-0 snd_hda_intel

$ cat /etc/modprobe.conf |grep usb
install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe uhci_hcd; /bin/true
blacklist snd-usb-audio
