 Posted: Sat Jul 18, 2009 7:32 pm Post subject: Microphone not working? |
 |
|
I'm trying to get Ekiga set up, but the microphone doesn't seem to be working.
When I type arecord into the terminal it outputs a string of 'x's. This is when the microphone is turned up so loud that I can hear it though the speakers. I get the impression that I should be able to do that.
If I load Ekiga, and running the configuration wizard, when I selected to test the sound it complained at me last time. Now it's not doing that. It is, however, meant to play my sounds back to be after a four second delay. It's not doing that either. This seems to be consistent with arecord's output.
My /etc/modprobe.d/alsa.conf contains
| Code: | # Alsa kernel modules' configuration file.
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
## OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##
# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
## OSS/Free portion - card #2
## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
# Set this to the correct number of cards.
options snd cards_limit=1
options snd-hda-intel model=6stack

The only change I've made is added the bottom line. This seems to be the closest (from /usr/src/linux/Documentation/sound/alsa/HD-Audio-Models.txt) to my system, which is actually an ALC888, but there are no options for ALC888s in that file.
Any idea as to why it's not working?

This might be obvious to anyone who can answer this problem, but I suppose I've just worked out how to use alsamixer (before I just tried as many combinations that looked reasonable as I could):
I've plugged my microphone into the rear mic socket, and set both input sources to 'mic' (rather than front mi, line or CD; this appears to make no difference though). I can only hear the mic through the speakers if mic boost is up all the way, and if playback for mic is not muted (now I know what I'm doing with these buttons (kind of) it's a bit obvious).
Wierdly, 'front' has to be turned up, to play anything (I'm not plugged into the front headphone socket though), and I also need PCM.
But arecord still doesn't do anything useful (or ekiga). Interestingly, the character that arecord outputs (repeatedly) varies dependant on the level of the 'digital' meter under 'capture' in alsamixer.
Anyone got any ideas? |
