amixer: Mixer load hw:0 error: Invalid argument -> Codec: Realtek ALC887 - card 0: SB [HDA ATI SB], device 0: ALC887 Analog [ALC887 Analog] - Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) 1002:4383 (rev 40) - microphone not working in Ubuntu 10.04.4 LTS

Asked by kent

Hello!

my mic is not working in 10.4. I have verified the mic works on another PC.

I have reviewed several previous posts on this matter -

1) here is the url for my system config:
 http://www.alsa-project.org/db/?f=b26279d15f2e217d27e9622d8d487489cc0f927f

2) i've installed the latest updates and rebooted based on another post:
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo add-apt-repository ppa:team-iquik/alsa; sudo apt-get update; sudo apt-get dist-upgrade; killall pulseaudio; rm -r ~/.pulse*

3) i've played around with the sound preferences to no avail. it does find an input and output device on the hardware tab...Ithey are assiged to "digital stereo(IEC958) output + analog stero input".

4) i've install ALSA mixer - but it won't boot up.

any suggestions? I really need to get skype working.

This is a known issue with the ALC887 sound codec.

See the following bugreport for details:

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/669092

Please run the following command in a Terminal:

gksudo gedit /etc/modprobe.d/alsa-base.conf

ADD the following single line using the gedit editor:

options snd-hda-intel model=generic

SAVE the change to /etc/modprobe.d/alsa-base.conf

Then REBOOT and retest sound using headphones and speakers and microphone.

After rebooting, make sure all channels are UNMUTED and volume set to 100% in alsamixer.
