starling (star1) microphone problem

[tlroche]

summary: A star1 running maverick/10.10 has 2 users, both admin. The built-in mic only works for one user. How to fix?

details:

I'm trying to setup Skype for multiple users on a star1. I login as me and do

me@it ~ $ arecord -f cd /tmp/junk.wav
Recording WAVE '/tmp/junk.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
# speak in the direction of the mic
^CAborted by signal Interrupt...
me@it ~ $ totem /tmp/junk.wav &

and I get playback of what I spoke. I then restart and login as another user, but

gf@it ~ $ arecord -f cd /tmp/junk.wav
Recording WAVE '/tmp/junk.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
# speak in the direction of the mic
^CAborted by signal Interrupt...
gf@it ~ $ totem /tmp/junk.wav &

produces no sound. When logged in as the other user,

1. I can play sounds, so I believe this is not an output problem.
2. In Preferences>Sound>Hardware, profile="Analog Stereo Duplex".
3. In Preferences>Sound>Input, there is only one device="Internal Audio Analog Stereo", and it is selected.
4. In Administration>Users and Groups, both users have Account type=Administrator.

How can I ensure all users can use the microphone (e.g., for skype) or debug the problem further?

Any ideas?

Can you check the individual permissions each user has? You can do this from System > Administration > Users and Groups, then click on each user and click on the User Privileges tab.

The same: for both users, everything is selected. (Note that this appears to be the meaning of "Account type=Administrator": if you uncheck any item, "Account type" changes to "Custom".)

From the user with working sound go to System > Sound from the launcher, then open the Hardware and Input tabs. Make note of how everything is configured. Then, from the user without working sound, go to System > Sound and make sure the settings are identical.
