Subject: [gentoo-user] Mic works, but doesn't work...
Date: Sat, 21 Apr 2012 18:17:16
1 Hi,
2 Ah, for a peaceful Saturday, but I guess not this one... I'm just
3 starting to investigate this but maybe someone's worked on this sort
4 of thing recently?
6 The bottom line is that my mic for conferencing is working, in the
7 sense that with headphones on I can raise the either the 'Front Mic'
8 or 'Front Mic Boost' sliders in the KDE mixer and I hear myself
9 speaking. However none of the applications I use the mic with - either
10 Skype or VirtualBox VMs - are receiving any audio. My main method of
11 testing the mic is the little app in Skype where you make a test call
12 and then it plays it back for you. I do love that sweet sounding
13 English girl who talks to me but I don't hear what I recorded.
15 I haven't used the mic in 2 weeks so I only know it was working 2
16 Saturday's ago. (We didn't have a conference call last Saturday
17 morning.) The kernel was updated from 3.2.1 to 3.2.12 on April 15th,
18 so that's changed since the mix worked. It seems that
19 /var/lib/alsa/asound.state changed as recently as yesterday. (April
20 20th)
22 The machine is Gentoo (mostly) stable, and has been since it was
23 built 2 years ago, and is updated nearly every day so anything that
24 changed in the last 2 weeks is a possible candidate for root cause.
26 All other aspect of Alsa are basically working. Everything can play
27 audio. KDE system sounds work. VMs can stream NetFlix, etc. The only
28 thing not working at the app level is the mic.
30 Any ideas where to look?
32 I've not rebooted yet on the off chance this is a one-off hardware
33 problem. I have restarted Alsa but it didn't fix anything. If the
34 reboot doesn't work I'll try dropping back to the previous kernel.
36 In the old days you would sometimes delete asound.state and let
37 Alsa recreate it when you had problems with a new version of Alsa.
38 Anyone know if that's still recommended?
40 Thanks in advance,
41 Mark
